Problem with A/C unit\HVAC: Intermittent no power
When I start the car the unit will not come on until about 30 seconds to a couple minutes later (no power\no display.) Then sometimes, when the unit is on and working, the until will just lose it’s power and shut off (no power\no display). I will check again, but I don’t have any codes… well none for HVAC anyway.
I contacted the guy on ebay that fixes these units for like $50 but he doesn’t think he can fix this problem. He says it sounds like a grounding\power issue. Which I agree. Unless you guys have another idea of what it can be.
Also, where is the grounding point for the A/C\HVAC unit?

Sorry I can't help with the problem but very interested to know what is causing this because I have had the same problem. It seems no one likes to respond to this kind of problem. I have seen similar questions before and they get no or little response. I have been learning to live with it so far.

A/C power intermitting
Please see Bill Curlee's post dates 7-21-05 concerning electrical gounding. I saw this tonight and it seem that this could be our problems. I noticed tonight that my back up lights are not working when the A/C has np power. Is you condition the same. The question is which ground is for the A/C blower controls? Hope this helps..

I haven't been able to take a look at it on my car yet. But if you have ever suffered from the wet passenger floor before, like I have, that might have corroded the ground connection a little.
I'm going to look at it as soon as the temp goes down a little here. I don't have a garage and hate working on the inside of the car in 100 degree weather.

Please see my response to "Code No Comm" or "A/C takes forever to come on" Seems we had the same issue. My repair was a new ignition switch. Part number 10308321 cost $75 and Labor $ 275. All problems fixed including many other codes including O2 sensor code triping the engine light and other comm issues.
