Fuse Help
 

My cigarette lighter, visor lights, (new visors) and storage bin lights all out. Can anyone tell me which fuse or fuses that is. And where is the fuse for hood lights so I can pull fuse.

Thanks guys

Re: Fuse Help
 

Thanks Paul but you are talking to a non-mechanic idiot. Lol. What is a hush panel and exactly where is it?

Thanks

Re: Fuse Help
 

Its the carpeted area between the passenger`s feet and the glove box.

Re: Fuse Help
 

What year car are you working on? You've several in your SIG!

If it's a '90 the "CTSY" fuse is NOT in the AUX panel under the hush panel. I believe it should be top left, first in the main fuse panel. I doubt that any year CTSY fuse would be in an AUX panel. That makes "no sense".

AUX panel has only CRANK-A/B, PWR DOOR, THEFT and FP2.

Hood lights are also on CTSY

I assume you know where the main fuse receptacle is but if not, open right door and it's on the exposed end of the instrument/dash panel.

Re: Fuse Help
 

Might wanna check your reference source, cuz I promise you on a '90 the fuse that powers the lighter, the map light on the mirror and the door locks IS on the aux box under the hush panel. Ask me how I know...;)

Re: Fuse Help
 

I don't find anything in the '90 FSM that contradicts what I mentioned. I'm not aware of any revisions so I'm left I guess with the ... "asking how you know"!

I noticed another post by the OP and I believe he may have issues with the "CRUISE" fuse but of course I don't "KNOW"! He mentions replacing some parts and I'm not really sure which. In this thread he mentioned wanting to disable the hood lamps so I believe the "CTSY" fuse should have been good so his problems mentioned in the other are likely NOT related to a fuse problem and he seems to confirm the fuse is good and actually I believe mentioned he "replaced".

Re: Fuse Help
 

Not sure we talking the same circuits here as Paul indicates the mirror lights, door locks and lighter in aux panel and what was mentioned in the post is the cigar lighter, visor lamps, under hood lights and glove box.The CTSY fuse powers some of those as WVZR1 indicates but not all and is in the main fuse panel. Maybe i'm not following this thread right.

Re: Fuse Help
 

Conflicting info - as to what circuits are distributed among the AUX block and the (CTSY) on the main block. I'll make a physical verification, soon as the rain stops and get back.

P.

Re: Fuse Help
 

If we're indeed speaking of a '90 fuse blocks and what's powered, 8A11-6 for the vanity and lighted rearview mirror (CRUISE FUSE), 8A11-3 for the cigar lighter, glove box, hood and misc. courtesy (CTSY FUSE) 8A11-12 for AUX BOX,

The complete courtesy and cigar lighter 8A114-0, 1, 2 & 3.

Re: Fuse Help
 

I didnt know there were lights for the storage bins.

Re: Fuse Help
 

It is a 90.

Re: Fuse Help
 

First thing I would do is check the cruise fuse and make sure that you understand the requirements that need to be met for the vanity, map lights etc to function under. I don't recall if some require "key on" or not. If you've a test light check each component for power at the device. If you want to check any fuses you do NOT need to remove them. All ATO fuses have 2 exposed ports on the plastic end that you can access with a test probe. It would be very unusual to have to remove a fuse to confirm continuity as was mentioned in your other post. Very unusual.

Here is an image of an ATO fuse that you can "zoom" to see the exposed ports that I mentioned. You can go down and around an entire fuse block and check in a matter of minutes. Just determine which should be powered "constant" and from "key on"!

Do you have a FSM? If yes see the pages in book 2 that I mentioned.

Re: Fuse Help
 

Initially depending on memory (first mistake) I did some testing/verifying to discover what is really what with regard to the 90, CTSY fuse (upper left corner of the main fuse panel), and the AUX FUSE BLOCK and was able to verified the following:

• The foot courtesy lights - come on when the door is unlocked with the key, but if the door is left open/adjar OR the ignition switch is turned to the ON position, they will go out.
• The MAP light on the rear view mirror will operate w/ or w/o the IGNITION (IGN) switch ON or OFF.
• The outside TEMPERATURE reading display will register with the switch ON. But, if the fuse is pulled/blown, the temp display back lighting will be present, but no digital temp display
• The speaker amplifiers AND the antenna will operate IF the radio itself is turned ON along with the IGN switch is either in the ON or the ACC position. (Note, however, the radio itself IS NOT powered by the CTSY FUSE, but rather a separate fuse. This is a little tricky, because the radio pre-sets display will indicate the radio is working, but there's no sound (and the antenna will not raise) which can perhaps lead one to conclude the radio is not working and lead them in that direction instead of the CTSY fuse.)
• The climate controls; A/C, heat, etc. will operate IF the IGN switch is ON
• The cigarette lighter IS ALWAYS HOT.

The AUX FUSE BLOCK: (apologies for the pic quality - the camera lacks a macro capability. I'll replace it when I get a chance.)

http://i185.photobucket.com/albums/x...psaa38e69e.jpg

The block is located under the passenger hush panel. The panel is held by two screws on the bottom edge, and one screw under the bottom right of the cover for the main fuse panel. (that panel cover is held by 3 screws). Find the AUX FUSE BLOCK located right of center of the hush panel, directly above where a passenger's right ankle might rest. The AUX BLOCK might be obscured by some wire harnesses that might have to be pushed aside to view/access the fuses thereon.

from the top:

• the primary fuel pump (FP2 - correction) is the 10A fuse (red) at the top
• the THEFT deterrent fuse, a 15A fuse (blue) is second from the top
• the power door lock is the third fuse fuse a 15A fuse (blue)
• the "CRNK A/B" fuse is a 10A (red) fuse (ref the FSM).

Sometimes when in the midst of troubleshooting problems consisting of several circuits which are further complicated by layers of switches and relays, and the occasional misprint in the manual, what controls what can get confused: - as apparently I became during my trek through these very circuits only a couple months ago. So, my apologies if I confused anyone earlier.:o:o:o

Re: Fuse Help
 

Almost correct Paul but the FP1 is in the primary fuse receptacle like all '90 C4's - bottom most right in the main. FP2 is in the AUX (only LT5)

Something that needs to be mentioned is that this is a '90 only configuration. In '91 I believe there are 2 AUX receptacles

Cliff - your images weren't there when I was doing mine. I went and confirmed in the FSM the FP1 placement. You can't read the lower row of fuses in your image any way so left to right: STOP/HAZ, WPR, ECM, FP1

Re: Fuse Help
 

The '91 with the addition of the additional accessory harness in the console the CIGAR was moved to the AUX 2 as well as the "keyed on" wire of the accessory harness.

Re: Fuse Help
 

Dayam, the AUX photo! Thanks, and I'll make the correction. However, there is another 10A FP fuse under the ECM...which I discovered too. Marc told me what it was, but I've not investigated it further - just re-attached it and moved on as part of the re-assembly process. Just why they scattered fuses all over the place is annoying, to say the least....:-x

Re: Fuses on a 90' and 91'
 

Your '90 has an incorrect "TAIL" fuse

Re: Fuse Help
 

10 AMP is radio, B CONV is cigar lighter and B+ for the accessory harness in console, I CONV is "switched" wire in console.

10 AMP top is L INST which does a multitude of LEFT functions, left door courtesy, LH window switch, Heater and AC control, DIC. Power mirror and radio control lamps. There's a R INST 10 AMP in the main block. It does get confusing on the '91.

The fuse value in the AUX 2 is deceiving, in your snapshot the value of the fuse is above the fuse and the function of the fuse is under the fuse. Next time you look the lower 10 AMP says RADIO below it. It took me a little to sort out your snapshot, it's dramatically different from the labeling of the AUX 1 where value and function are combined.

OP is likely ready to kick all our a$$es but I really believe he just needs to concentrate on the CRUISE fuse, the CTSY fuse and check each component separately if those fuses are good. I believe he should be good to go with no major issues! That's all I intended was to get the OP to concentrate on only those 2 fuses and circuits so that he could disregard the removal of the RH hush-panel etc.

Re: Fuse Help
 

After I looked at your snapshot I redid the response and ID'd both 10 AMP fuses because your snapshot looked to be a little short on the AUX 2. Yes CDM.

'90 cigar was covered yesterday - CTSY 15 AMP.

Re: Fuse Help
 

I'm so confused. LOL

Re: Fuse Help
 

Are you still asking the question:

What is I CONV PL and B CONV PL on 1991 Auxiliary Fuse Panel. And what is the Top 10 amp fuse on the 1991 Auxiliary Fuse Panel?

If yes I explained but will again. In '91 there was an accessory harness added to the console of the car for accessories. There are 3 wires B+ (12V), IGN (12V SWITCHED) and a ground. B-CONV PL is the fused B+ lead and the cigar lighter, I CONV PL is the IGN 12V switched lead. PL = PLUG I guess. In the console there will be an ORANGE (blunt cut) B+, a PINK/BLK (blunt cut) IGN switched plus a ground.

The top fuse is the L INST which I explained. In AUX 2 the AMP is above the fuse and it's function is below the fuse. I explained earlier what L INST controls but again it's the lamps in the mentioned switches and panels.

Do you use the accessory (blunt cut) harness (wires) in the console of your '91? Did you know it was even there? I thought I had seen you reference the wires/harness previously. Maybe NOT!

Re: Fuse Help
 

I'd just like to see the OP respond with a "FIXED" when he's completed his fix. The rest of this has been mostly uncalled for and it's become even more confusing as it carries on. I wouldn't mind if the entire thread went away as soon as the OP mentions "FIXED" in either of his threads.

Re: Fuse Help
 

Actually, I think there is good info in here and I learned a few things I didn't know but maybe time to put it to rest as WVZR1 says. While the brotherhood is providing valuable info, you definitely need a service manual with wiring section if you are going wire/fuse/component/values tracing etc. Good luck Mickey D.

Re: Fuse Help
 

Did not intend to make you mad, but as I had mentioned, I am not a mechanic, it is a 1990, and just thought it might be a fuse. I did not mean to put this thread in GP, so I also put in TP. I made a mistake, sorry! I will certainly tell everyone when it's fixed. I've had my mechanics (cranes not cars) check all fuses. I am taking it somewhere today. Sorry again to have bothered you.

Re: Fuse Help
 

You were no bother at all. I just wanted to get you directed to which fuses should control the components that you asked about and there should have been no reason to pull the hush panel. AGAIN - you were no bother. Once you mentioned '90 I thought the thread would stay focused on the '90 but then it got complicated with the addition of the '91.

Good luck with the fix and I'm amazed that it wasn't just a fuse issue but maybe it's actually just a bad component.

Did you get the under-hood light working with a bulb replacement? Now your issue should only be the cigar lighter and the glove box I believe.

Re: Fuse Help
 

Before you guys put this to rest........:p

For those with 1991 ZR-1s there is a difference between the 1990 and 1991 Primary and Auxiliary Fuse Panels.

1990 and 1991 Fuses
