My 2003 Grand Caravan Sport rear A/C issue
Hi all, i would like to post my first thread about my van. Great van, and it's been treating us here very well.
I do have a problem with the A/C though. I just got it repaired last year, and now the back A/C isn't blowing cold air!
I think there's a vacuum line off or just a loose wire somewhere, but not sure where to look first!
The front A/C is nice and cold by the way.Just wondering if anyone else has this problem, or knows of the solution for the home garage guy.

From: ft lauderdale, fl area
MOst likely the rear expansion valve located inside of the rear inside panel of the van. See attachment for explanation: http://www.youtube.com/watch?v=S8sYR...eature=related
I replaced the expansion valve. the part was 35 bucks. This is common weakness in these vans. rear valve goes out. then you need to refill system with 134a around 3 cans and first vacuum line, although mine wasn't because i didn't have the money to get it done, and soon as opening of the line of the rear expansion valve i plugged a/c line with a cork or run tape over it.
If you put a a/c compressor in when you had it repaired, then i wish you knew if it was flushed out because of metal pieces that maybe lodged within the a/c line in the rear stopping up the gas, liquid from going back to rear.
Somebody else please chime in and find away for this gentlemen to troubleshoot other then what i told him.

Hi all and thanks for the replies! Yes all the air was working both front and back when i got it repaired last year.
Now all i have is the front air, and it's working just fine.
The rear air did working once last week, but now it's just blowing out warm air.
I have tried both with the recirculating inside air on and off too.
Guess i may have to drop the panel form the inside roof of the van that also houses the DVD player and air controls, just to take a peak.
There are two ***** there, one to choose the intensity of airflow, and the other for warm or cold air!

Does Heat work for the rear? if it does, then the blend door should be fine. ur problem is probably the H-Block as posted.
