#490 of 511 2004 Grand cherokee air condition problems by sarnel

Last night the air conditioner on our Cherokee just stopped working. The air conditioner light does not come on when you push the button; there is no air blowing out, no air coming out when the heat is turned on either. The light does come on when you push the defrost button. Please help.

#492 of 511 Squealing Behind Dash by rhickmanjr

Aug 22, 2011 (10:43 am)

I have a '96 JGC. When i'm traveling over 65 mph and it is hot outside there is a squealing noise that occurs. It appears to be coming from behind the radio cluster..more on the passenger side. It occurs if the A/C is running or not. If I slow to under 65 mph the squealing stops. It does not occur when the temp. is under 90 degrees outside so I never hear it in the winter or early morning summer hours. It does not occur if I travel over 65 mph and is cool outside. My conclusion is that a combination of temperature and speed is triggering this to happen. Anybody ever hear of this problem??

#493 of 511 1996 jeep grand cherokee electrical trouble by jaedymack

Aug 25, 2011 (6:32 pm)

ok, I too am having the same crazy electrical troubles. I guess I still haven't seen what the cause is. My sunroof will come open on it's own, my a/c will now only blow on defrost only and will not change with the selector switch, my factory radio will not turn the volume up w/o spinning the knob several times, and my electric windows sometimes work and sometime dont, and my cruise now does not work. The light comes on but when I hit "set" I get nothing. Thanks for the help. Matt

Thanks for the info. Found a vacuum leak right by the firewall in the engine compartment. A little electrical tape around the hose solved the problem. I save a bundle, I guess.

#499 of 511 Low volume from climate system by jsonger

Apr 01, 2012 (6:55 am)

I have a '01 GC Limited with the auto climate control. Have replaced all actuators and still get low air flow volume. There is no cabin filter and no trouble codes from the system, just not a lot of air coming out no matter if defrost, heat, or vents. The fan seems to be running at all speeds and there is no blockage in the area around the fan's wheel. Could this be an issue with the fan control resistor block? I welcome any suggestions or similar experiences
