98 caravan ac problem please help
 I have a 98 caravan that the ac will not blow cold. Everything is working fine ,it blows cold air until the temperature gauge gets up to operating temp then it starts to blow hot.The climate control lights were flashing so i recalibrated it and after it was done the rear wiper button and and the intermitten rear wiper button lights are flashing some kind of code. The top will flash once then the middle will flash 3 times then the top will flash once then the middle 5, and then the top once and the middle 6 times .What does these lights flashing in code mean and what could be causing the ac to act the way it does?

Re: 98 caravan ac problem please help
Not a clue on your flashing code but if you attemp to do the calibration procedure with an inoperative a/c your lights will flash till the a/c is fixed. Have you put gauges on the system to check pressures? Most hot A/C problems are causes by low refrigerant.

The system is fully charged clutch engages lines get cold all doors seem to be functioning properly. I recalibrated it about 2 months ago and the ac started working fine until the battery went bad and now it doesnt work. Now even after i recalibrate it the air is still hot.

Re: 98 caravan ac problem please help
This talks about location and accessing it. Can't help much beyond that. There is probably a resistance check on the probe. Hopefully you'll see something obvious.
http://www.dodgetalk.com/forums/arch.../t-209828.html I also read this temp probe shuts off the A/C compressor if the evaporator temp gets too low. Funny how wiring diagrams don't show this little gem. By the way - Born and raised in Michigan City up on Lake Michigan.
