HN Year All: Do you have to remove the radio trim panel (bezel) to access the hazard flasher on a '91? According to the service manual, only the right side lower trim panel has to be removed, but can't see how you can possibly access the hazard flasher (mounted on the radio receiver) by just removing the lower trim panel.
Thanks.

Removing the passenger side lower trim panel will provide access to 5 relays one of which is for the hazard. These are bunched in 3 plus 2. You have to reach in from under and pull towards the front. Make mental note of pin configuration as soon as you pull. This will make it easier to plug in the replacement. Refer to the manual to identify which one you need to remove.

Much appreciated, but according to the service manual, none of those five relays are for the hazard flasher; they are: RW defogger, horn, fuel pump 1, dome lamp and fog lamp. The four-way flasher is on the radio receiver according to the service manual, but I cannot see how you can get access to it by simply removing the lower trim panel as the manual indicates.

We need someone with 91 manual. Mine is a 94. There may be a couple more relays under the driver side. I removed and serviced a few radios on various years but never noticed hazard flasher relay behind the radio.

Why are we going after the hazard flasher? Just curious. I can't imagine it being that difficult. Pull the hush panel and with a light and a mirror you can put an eye on it. I've never gone after just the flasher in mine but I certainly can't imagine it being a major undertaking. HIZNHERZ just did a heater core in a '91, he may recall.

The hazard flasher replacement is required due to the conversion to LEDs; the signal lights work fine with the turn signal flasher replaced with an e-flasher, but the four-ways aren't working properly, so I'll have to do an e-flasher conversion for the emergency flashers. I am using section 8 of the '91 service manual, and it looks like simple access to the hazard flasher (mounted on the radio receiver) with just the lower trim panel removed, but hell if I can see it much less access it. Thanks gents!

I mentioned light and a mirror!

The flasher is right behind the CDM ...91 FSM 8C-28--31 shows the location.

I just did a heater core on my 90' and I recall the flasher being in a clip behind the CDM. I think I popped it out of the clip and popped it back in after re-installation of the CDM. I also think if you reach up behind the CDM you can just feel it and pop it out of the clip.
I recall the Flasher Clip is attached to the black plastic plate which is attached by the two 10 or 8mm nuts on each side of the CDM. I think also on the rear end of that plate near the flasher is the second fuse block with a second set of fuses. The Flasher is a typical cylinder maybe 1.5 inch diameter and maybe 1.5 inch long. I recall the electrical plug on the flasher has a pig tail.

Thanks guys. I'll keep this in mind when I get back at it tomorrow morning.

The image I posted is from a '91 FSM and it should be exactly like what you experienced in the '90. I was pretty confident it was "reachable" without releasing the CDM tray etc. but I can't go confirm it.
The mirror and light I would certainly think confirms it all. My image is from the 8A-201 section of the FSM>
