Cold AC From Drivers Vents, Warm From Passenger Vents

Hi guys,

My '05 3.7 JGC had a weird problem today. I drove with my wife to get some lunch and on the way, A/C was ice cold coming from all vents.

After stopping for lunch, we get back in the Jeep and only the driver's side front vents are blowing cold - the passenger vents are blowing warm.

The system is not a dual-control climate system, just the simple Laredo setup.

Any ideas are appreciated!

Re: Cold AC From Drivers Vents, Warm From Passenger Vents

This has been happening to my 05 3.7L Wk for 5-6 days now... I'm going to try and take a look at the air ports in the dash for any buildup of dust or anything else. If anyone could help solve this problem, Quarterwave and I would appreciate it thanks...

Blend doors are broken its an expensive repair, you have to remove dash.

Re: Cold AC From Drivers Vents, Warm From Passenger Vents

I was going to chime in saying that the vent that sucks in warm engine air is stuck or broke.. at least that seems the most logical cause.

The vent that controls that is the blend doors or recirc doors

Re: Cold AC From Drivers Vents, Warm From Passenger Vents

In canis' thread about warm air from passenger and rear and cold from driver, he said that the wk was simply low on refrigerant... Should I just go buy dome refrigerant, before I investigate the broken blend doors..?

Re: Cold AC From Drivers Vents, Warm From Passenger Vents

I added a can of refrigerant and still nothing...i called around to different dealerships and they said it would actually be cheaper to bring it in, then to just by a blend door from them and it be the wrong one... But now all of a sudden, the WK is blowing cold air all around... This WK just confuses and amazes me everyday...
