Re: Air conditioning thoughts?

A/C works fine--I just hope the WK2 HVAC design has resolved the flippin' Blender Door problem...which cost me thousands of $$ to fix (twice) with my 2001 WK JGC.

Anyone know if the blender door design on the WK2 is improved over the WK? (I pray)

Re: Air conditioning thoughts?

Anyway someone could provide a A/C system schematic and details on the system for the 3.6L WK2?

With that we could tell if the system is designed on the smallish side or not and if the issues people are having are mostly control/software related.

Also, we could see if it would make sense to add a receiver (or larger receiver) to the system and possibly add more refrigerant and gain more subcooling before the expansion device. Also we could see about potentially changing to a different expansion valve (assuming the systems uses a valve and not just capillary tube).

Not very strong AC, but still much better than in mine former 2009 Laredo. With recirculating on it is fine but defenetly not superb.

Is "I could hang meat in the jeep when the temp is set to low" an actual temperature?

Re: Air conditioning thoughts?

My wife and I experienced weird AC issues this past 4th of july. We were making a 5 hour drive from DC to PA. Around the time when we hit the 3.5 hr mark, the AC started to die. I mean literally, fan speed lowered and got warm. You could hear the blower churning but no draft was coming out of the vents. This was on the manual setting at about 69-71 at full fan speed. Normally we wouldn't even need the fan on high at all. After shutting it off and running with the windows open we restarted the AC and it worked fine. This was on an 83* day. We then experienced the issue again and the jeep got terribly warm inside, we then used the Auto setting which we had not used before with the recirc option and it started to cool down. I took the jeep in today for a leaking gasket on the V6 engine and I forgot to mention it since it hadn't done it since. By the way the dealer decided that they would clean the engine up to check out the gasket in detail during the next service visit?? Not sure how this is going to prevent a catastrophic engine failure??

Any ideas on the AC?

Re: Air conditioning thoughts?

Sometimes it blows icy, sometime just cool. Seems to blow coldest under moderte acceleration or when cruising. Warmest at red lights. I would prefer icy all the time... It is a little disappointing.

I have manual controls and am referring to when they are on full power AC / recirculate

Also, a small GRIPE: Why do my aforementioned manual controls take like 6 seconds to engage once the car is started? Thats a hot 6 seconds I shouldnt have to wait! Most cars engage instantly.

I think what it does is it waits til it can blow cold air which is why sometimes it can take a couple seconds for the vents to come on.

Some have reported freezing up (ice collecting on the exchanger reducing air flow) and low refrigerant fill.

They cleaned the engine either to verify that the leak was fixed or to better determine which gasket is leaking, or if it was just a initial build thing.. A leaking oil gasket is not going to lead to catastrophic engine failure unless you are not checking oil level regularly and letting it all leak out or its such a bad leak large puddles form on the garage floor.

You would prefer blowing hot air instead? Most cars, except the very basic, will delay AC blower operation for a few seconds to allow the evaporator (heat exchanger) to cool before hitting it with hot air... new gas and compressor types. If you want cool air right away, remote start the vehicle 10-20 seconds before getting in. It will be blowing cold by the time you open the door.

Re: Air conditioning thoughts?

My GC LTD gets super cold. Have to point the vents away from me.
Make sure that all the vents are OPEN, as they can deceive. Love the Auto temp feature, a little disconcerting at first if not use to it, but now just set it for 72 and ignore the rest.

They didn't fix the leak, it was still leaking. The engine was spotless when I bought it. It would lead to engine failure if the oil leaked out during a long drive. My point is that my warranty covers gaskets, why didn't they replace the gasket which is obviously leaking. People always try to take the easy/cheaper way out.
