Hello everyone!! Newbie here. I am sure you have had this question posed a million times, but I'm having difficulties finding info on my exact situation. Recently bought a 1989 Cherokee Laredo and as expected, it has a few issues here and there. The newest one that is blowing my mind is with the heat and a/c.
When I bought it, the heat and a/c worked but only through the defrost vent up top. I went searching for broken vacuum lines, but found nothing. Didn't sweat it, but now nothing is working at all. I turn on the heat or a/c and I get no air, no noise, no nothing. Completely dead! I did just change out the blower fuse and still nothing. Any advice???
Also there is 12.someodd number of volts going into the ignition and gauge in the back of the gauge cluster circuit board . So i have power and a sender signal to the gauge. As far as i know the ground is good. What do i look at next?

How do you know the sender works? I haven't been following this.
Yerp. thats about right jeep was 171 when i did the test
Interesting. I'd unplug the gauge cluster and check resistance on that wire's pin. If it's different, you have a short. If it matches, you probably have damaged circuitry on the gauge cluster

Just means a new gauge cluster if that's the case. They aren't too terribly hard to come by, and I could show you how to alter the mileage to match, purely for educational purposes
Hi Funkman1025- question, your Apr2010 posting of Jeep interior. What year and model/style is this? I have a 2001 Cherokee Sport and driving me crazy with electrical problems, want to purchase same Jeep I use to have and if I recall interior looked like this (only complete)
Good luck getting an answer four years later lol.
However this may help you: the "new" interior was installed in 1997-2001 model year XJs. Everything is the same. Some higher trim models have nice bits like wood grain and a couple color variations, but that's it.
For the most part 1984-1995 are the same. 1996 has some oddities but is largely similar to the early years.
Here goes- 2001 Sport- several questions.
1. power windows- when I raise window from power button- terrible noise as window stops at completely up. Sounds like a gear worn (kind of sound of automatic weapon burst). What do I need to replace?
Window regulator. It may just need cleaning, though, so get one you can return for a refund if you don't need it.

Do I need ignition switch? I know I need key tumbler.
High five on A)! This is popular, my favorite feature. It sounds like you have a really worn lock cylinder AND ignition switch. The previous owners probably had a MASSIVE keychain with a ton of weight hanging off of it. This is basically what's causing all of these recalls for GM.

I have not observed at moment needle pegs on gage. If I turn ignition off and back on everything back to normal or if I continue to drive light goes out and volt gage back to normal. I see needle sitting above 13 v and can watch it creep to 14 volts and then it may sit there or go up slightly and then it pegs out and check gage light goes on. Never have check engine light come on.
Pop out the instrument cluster and take a look. These connections become loose sometimes or the ground back there may be shot. For the connectors on the vehicle side you can "tweak" them with a dental pick or similar so they they grip the blades better. At the least give 'em a clean with some contact cleaner.

Also when pressing door lock, window lock, etc the lights on power outside mirror directions go out. I have ordered a new controller to see if that fixes it all. Wondering if anything in fuse box would cause all the other window not to function and only work from divers door?
These are VERY common problems. The window issue is caused by a busted lock switch in the driver's door. There are writeups on how to bypass this switch and restore function. Do a search for this one.
The door lock button affecting background lights is a ground problem. Check the wiring between body and door. I'd be surprised if all your speakers work! Don't hold your breath for that controller fixing anything...

Nope.

I hear ground, ground, ground usually the gremlin. Is there someplace that defines the ground locations? I hear engine to firewall, under driver side dash to frame. Help anyone would be greatly appreciated. I need to get jeep ready to get through a Minnesota winter!
Yep grounds. Look around for some information from CCKen, both here and on naxja.org (you can search these forums via Google). He's posted the '97+ grounds a few times. There are a lot of low-lying ones in the body that rust eats and an important one above the fuel door.
