I have a similar problem and I suspect the ac relay. How do you get to it and what is the part number to replace. Where can I find a new A/C relay. I do not hear any clicking when I turn on the A/C. Fan works properly, blowing hot air, compressor not kicking in.

It cut off on my husband twice yesterday, once on the highway as he was trying to speed up and car was dead, another time as he was slowing down coming off the ramp. I have not noticed anything...

You really need to look for the coolant temperature sensor. It screws into the thermostat housing. www.fcpgroton.com has both on the same page so you can see a comparison.

Thanks. Is there a way to test that the one you have is bad ?

We just bought an 93 850 for my 16 year old son. Car drives well, idles nicely but it stalled on him once while slowing down for a red light. Another time it stalled at the mechanic when they just let the car idle after they replaced the radiator fluid. It was idling for quite along time, then they ...
