Ok so, I have a 2001 Dodge Caravan SE. A/C does not blow cold, clutch works, pressure drops to about 75 psi then goes back up, fans do not come on except for High engine temp, when they do come on for High engine temp, NO COLD AIR. I have been trouble shooting this thing for weeks and am outta ideas. and its crazy hott here. HELP!!!!

 

bummer, so you're A/C certified and licensed right? If not, by law you can't be messing with it.

in this weeks of trouble shooting, what kind of scanner did you use? and you monitored both high and low pressure correct? you verified that expansion valve is working properly? what are the temps of the low and high pressure hoses? and we'll assume you verified that the blend air door is working properly in the heater box?

 

Welcome to DF
Keith what repairs have been made on the a/c system? It could be many thing as sapporo was saying,Bleed doors,rec door, condensor, or expansion valve.

 

LMAO dude he's looking for some help! I'm really sorry to flame (especially a senior member and I know from past experience you know your stuff as well as anyone) but if you're gonna feign trying to help by asking a shadetree wrench questions you know he can't answer, then why waste your time typing? It's like you just went out of your way to make a new member who's already frustrated feel welcome. Way to make a first impression!

And the cert and license must vary widely by state, here in TN I have no problem getting gas, etc at the store. If you do it for a living or for other people I'm sure it's different, but the nanny state hasn't gone far enough to tell you you can't turn a wrench on your own car. Not yet anyway.

OK done hating for the moment

Keith, the first thing I would do is try this:

I did something like this on mine and all of the sudden everything worked.

I might also start looking for a bad relay or whatever is causing your fans not to come on.

Let us know what happens.
