#493 of 519 1996 jeep grand cherokee electrical trouble
Aug 25, 2011 (5:32 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 519 Low volume from climate system
Apr 01, 2012 (5:55 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

Did you ever get an answer to this problem? I've got the same issue with my 01 GC Limited. No one has offered any advise. The fan blows pulling 12.5v, no trouble codes, blend doors work, recir door functions. No significant air flow.

Hi, I got an answer and it is fixed. Seems the costly mechanics put the little piece in backwards (the blower control) and it was turning the wrong way. I researched the problem, called Network and told them, they told me I was female, blonde did not know what I was talking about so I took it to a friend who works on AC's and RV's and he looked at it and said "hey it is turning back wards", he changed the wires and the thing works just fine. We still have a blend door not functioning, but at least the blower is blowing at 100%.
#502 of 519 vacuum line and speedometer
Apr 11, 2012 (3:10 pm)
OK.....I've been reading all these posts on here, but I just can't find out where one certain vacuum line goes. It hooks into the 'main' line just above where the a/c hoses go through the firewall. But it is a short line (could have been broken off) and there are no other lines coming through the firewall at either hoses, a/c or the heater hoses. I've tried to post a picture, but I'm doing something wrong and it won't post. OH...and the selector switch for the heater/defrost IS stuck on defrost...and if that line goes through the firewall.....where does it end up at ?? OH and it is a 93 Jeep Cherokee Loredo.
Also, my speedometer hasn't worked in God knows how long, and I've replaced the VSS, and it still doesn't work. When the speedometer doesn't work, then neither does the odometer and the speed control. The tachometer works just fine, it's just the speedometer that don't work......any ideas ????? I need help....... Thank You
