#343 of 372 '99 Grand Cherokee AC compressor clutch by sethybob Jul 01, 2009 (10:38 am)
The clutch is sticking and at times won't engage at times without a little tap on the front of the pulley. Any recommended cleaning procedures for the clutch? Replies to this message: sethybob (Aug 17, 2009 6:21 pm)
#344 of 372 2001 Jeep GC Limited AC only blowing hot air by danierob Jul 04, 2009 (12:38 am)
Hello, Here is my problem. I have a 2001 GC Limited V8. About a month ago when I hit the ac button it lights up but all I get out of all vents is hot air. It never cools down. I had the coolant checked, thinking that I needed to fill it and I was told that it was full. I remember hearing something click on when I pushed the ac button, maybe the compressor after reading some posts. I do not hear that noise anymore. Could this be a relay switch or fuse or am I in for some big bucks to get this fixed. Let me stress that I get no cold air but hot air blowing out of the all vents. Thank you for any advice/help.

#345 of 372 2001 JGC A/C problems by lugnut42 Jul 07, 2009 (8:43 am)
I have a 2001 JGC V-6 w/ dual controls and when you turn the a/c on you can feel cool air but it won't blow. You can feel cool at the defroster, the vents and at your feet all at the same time. Is this a blend door problem?
#346 of 372 2004 Jeep Grand Cherokee AC problems by bradc1 Jul 15, 2009 (4:03 pm)
Sorry if this question has already been asked. I just bought a 2004 Laredo with a 4.0L. Strange AC problem is happening. The AC LED intermittently goes out. If i press the rear defrost button twice, it comes back on! took it back to the dealer. They found a cracked vacuum hose, but the problem still remains. It doesnt do it all the time, but it always seems to comes back when i hit the rear defrost twice. when the light goes out, it blows warm air. It blows cold air normally when the AC light is on. Any ideas??

Replying to: skinsfan1 (May 19, 2009 3:23 pm) My wife has a 2003 grand cherokee laredo. The problems are the 3 control Knobs that control your air.$450. includes control knobs and to be on safe side the expansion valve. included recharging the system....... It took us 5 years to figure it out.....
#348 of 372 2003 Jeep problems by bradyr Jul 20, 2009 (7:35 am)
I have 2003 GC limited 4w quadratrac with a few problems and any help would be appreciated as the dealers I take it to care only about money and creating new problems for higher payments. I have had the vent problems and heating problems and replaced twiced in 2 years. Now the heat/ac and temp. settings work fine but I only get heat/ac from the defrost or floor vents. I was told I need a new control panel for 750. Dont remember code numbers but more or less the two motors werent working directing the air flow. Next, there is a constant clicking when the car is turned on coming from behind the driver side dash- dealer couldnt tell me what that was--kinda funny. Next- at low speeds when turning- there is a whinning from the engine- possible belt problem was my first thought--a second opinion would help and last- when on the freeways and hitting the sectional gaps in the freeways- I fell heavy vibrations through the floor- (like hitting a metal poll with another metal object- the vibrations that go through your arm and hand) possibly shocks or maybe stablizer bar if there is one. Any help regtarding these few problems would be greatly appreciated as I somewhat like to know whats going on with my car before I take it anywhere...thanks again and have a great day.   Bradyr
#349 of 372 Defrost Only by socaldon Jul 27, 2009 (9:06 am)
Hi Guys,   I saw this question earlier in the thread but could find no replies. I have a 1997 JGC 4x4 V8 and, whilst the air conditioning seems to work, the air will only blow onto the windscreen. It doesn't matter what the control is pointing at - it refuses to blow air out of the vents.   Any ideas? Thanks in advance.   Dave Burbank, CA - a little toasty round here so help would be appreciated! Replies to this message: jdeaton (Sep 06, 2009 12:14 pm) socaldon (Sep 06, 2009 6:40 pm)

1999 JLC no cold air coming out of the two vents on the righthand side of the vehicle. two leftside, and two center vents appear to be working ok. what do you believe is my problem, some one mention the vacuum hose on the rightside under the radiator filler bottle?
