Re: ZR1 Detectives
Scammers wouldn't exist without gullible buyers on the other end. And like they always say, "if it sounds too good to be true..."
If you do contact the FBI, they would be interested in the domain...

Re: ZR1 Detectives
If you still have the copies of those ads or a record of the sites that listed that car, I would report it to the internet fraud division of the FBI and they will track that down real quick. I ran...

Re: A/C blower fan won?t turn off

Re: 1990 AC question
If the Freon level is that low that the compressor will not engage, you have to bypass or short the low pressure switch to turn on the compressor to get Freon into the system. You will not be able to...

Re: New engine whistle/whine
I remembered that after I made the post above and will do that later today when it warms up a little so I can go out. Could be that the squeal on start up is just related to the cold belt. I never...

Re: New engine whistle/whine
Can't hear anything with a stethoscope 'cause everything is rotating and you can't get on it to locate a noise.
I have now a 1/2" breaker bar that should fit the tensioner, I think I was using a...

Re: New engine whistle/whine
I'll have to make up a mechanic's stethoscope and try and track down the source of the whistle. It's very faint now only at idle and rapidly drops in pitch as it fades as I turn the engine off. Right...

Re: New engine whistle/whine
If it were a pulley or other bearing going bad then why would the whistle only occur at dead low idle and not increase in loudness or pitch with increase in engine rpm?

Re: New engine whistle/whine
This morning that whistle is only heard at dead slow idle, as soon as you rev up the engine even slightly it disappears. So I think it's related to the belt, maybe exacerbated because of the cooler...

New engine whistle/whine
I changed my oil/filter today and then ran the engine to circulate it around before checking the level again, and heard this high pitched whistle/whine when the hood was open. Don't really hear it...

Re: Stalling sometimes at stops?
Here's a totally different take on that problem. Mine did that twice one day a few years ago- stalled at a traffic light, was able to restart it immediately. Then about a mile down the road, stalled...

Re: 95 Slave Cylinder Replacement Cost
The slave cylinder itself, IIRC, is about $80 or more depending on where you buy it. And you also need to buy brake fluid. It's not particularly difficult to replace, I did mine, but you either need...

Re: '90 blower control module
Thanks for that. I found one for 20% the cost of those advertised for a C4, exact same part but there's no "Corvette Tax" on Jeep parts.
I know my module is bad because I tested it and there is a...

'90 blower control module
Today after a ride when I stopped and turned off the car ('90 ZR-1), the AC blower motor continued to run with no effect on it from the control buttons. The only way to turn it off is either to...

Re: A/C stopped working
The AC controller under the driver side dash has nothing to do with the compressor, it only controls the vacuum lines to the various doors in the duct system to direct the airflow.
Do you have any...

Re: Another poor airflow out the HVAC vents thread
The other thing about the foam is, I have no idea if that comes from the sealing of the various doors to direct the airflow, or if it comes from where the ducts join to one another, where, if that is...
