Hi, My grand Caravan's A/C is not working Charge is OK, Pressures are ok,low 30, high 250 and cycling but blowing warm air. Can any body tell me whats the problem.
Thanks a lot. Any help is highly appreciated.

 

Are you getting a trouble code?

 

not sure if you have rear ac or not but check to see if the rear blows cold and the front hot. most likely it is a mode actuator. have the vehical running and switch the hot cold **** from all the way cold to all the way hot and listen for a change in air movement noise.
(if your not sure what im talking about try it in a known good vehicle first). if your not then you have one of 3 problems, bad control head, bad actuator, or the door has spun past its stops.

 

Thanks for all the help A/C Working properly now.

 

libedavi,

we are having problems too. what did u do to check your and fix it? can u give me details as to how you got access to the system and what u saw?

Thanks,
Cory

 

Actually I just make sure that I've got the right charge. I think its 3+ lbs because I've got a rear A/C. It says on the hood anyway how much you can charge.
I removed everything evacuate it (Vacuum Pump) and charge with the right amount of 134A. There you go it runs well.

 

I am having the same problem. A/C Blows HOT air the compressor never cycles any suggestions? Wife is Hot so I am in Hot Water Help!
