2 different A/C problems!

oo-gonzo · 06-18-2007, 04:39 PM

Hey Guy's, I have two different vehicles with a/c problems.Wondering if you guy's could help? 1st-2005 Dodge grand caravan rear air blows cold and strong, but front air doesn't blow at all. Every now and then at high RPM's you can feel a little cold air coming out of the front vents. No strang noises or any other problems are involved in this vehicle.
2nd- 1994 GT. turning on the a/c it blows nice and strong, but not cold. tried adding coolant, but gauge shows a high coolant level. I tried to squeeze some coolant in, but it will not take it. The clutch isn't turning nor does the fan come on when a/c is wide open. I'm thinking that the cycling switch may be bad, but don't know how to check it. What do you think! The stang is killing me. Black car w/ black leather, Dang it's hot!!!

Caravan is proablly going to be something in the fan blower control(poss. switch) but i belaive they are intergrated with the whole havc controler.

Mustang check all fuses and the a/c relay. If you take a paper clip and jump the low side switch it should kick the compresser on along with the fan.

This should help you figure out where/what you need to test on the Mustang.

Wow! That is nice man! I realy appriciate it! Got the caravan checked out today. It is a bad resistor for the front blower motor. Cost me 414.95 + tax at the dodge dealership. Easy plug up right behind the glove box. Very happy with that! I will give it a try on the stang, Thanks!

That's $14.95 on the resister! My bad, Type-o

I was gonna say resistor when i read the first post. but looks like i was to late, glad you got it fixed though.

on the stang jump that low pressure switch like mentioned. but sounds like a pressure switch or bad compressor. do you have gauges for A/C work? they will tell you alot.

oo-gonzo · 07-03-2007, 12:20 PM

No, I do not have any guages for A/C work. All fuses were checked and good. I haven't tried jumping it yet, I think I will let an experienced person do that. I'm so tired off melting in the car that I am going to put in the shop to get fixed, whatever the cost! It's redicuosly hot these day's!lol

Took it in to the shop today. Steve put all the instruments and gadgets to work on it. found out that it was just a bad wire. Ran a new wire and now have cold air. Yiiiiiiiiiipeee! No more sweaty leather seats! Man I forgot how nice it is to have A/C in the summer time! Oh, and it didn't cost a thing for the fix! Here's another YiiiiiiiiiiiiiPeeeeeee!
