I've read the A/C thread but I need a little help.

A/C in rear is cold, not in the front.

Replaced the compressor, dryer, vaccumed out and replaced Freon. I'm not sure exactly where to go from here and it's hot in Florida right now!

The E-fan runs sometimes after I turn the truck off but not always.

On a side question:
I've got some weird quirks in my truck. Like the the wipers work when the key is out? What's up with that?

Thanks for any help.

 

trdavis....i think several issues

first what year (MY) ,engine etc?

i would start with fan running when eng off, do not want to get stuck W dead batt.
swap or replace fan relay.....easy cheap ....timer module maybe(MY?)

next what are the pressures. A/C high side and low side? 2 thoughts -blend doors, or metering


the wipers next what model yesr? timer module comes to mind BUT M.Y.


PS....unlikely you use FREON...MORE LIKELY surva R134a...**** I know but freon is expensive

 

Most likely a blend door issue.

 

I would think so as well, but i am no A/C man

 

Sorry I should have provided the year and etc. 200 Durango 5.2 V6 Magnum.

I replaced the relay since that was cheap and easy, but now the e-fan isn't working at all. Very strange!

i'm not sure what the pressures are. I had the freon replaced at the shop. I had the lines vaccumed and refilled. Although I do think he said the high side was reading lower than it should. Which is all null and void if the e-fan isn't working since I can't run the A/C now.

Would the timer module fix the e-fan and the wipers issue?

 

First of all the 5.2L is a V8.


Put the other relay back in and look at the blend door.
