#11 of 20 Jeep Cherokee electrical problem by pededard

I had the problem with the instruments going to zero while driving and would have to hit the face of the instrument panel with my fist to fix it temporarily. I partially removed the instrument cluster (could not remove it completely because I could not figure out how to remove the headlight switch knob). I found that the four or five phillips head screws that hold the panel together were all somewhat loose. I tightened all of them and replaced the cluster and have not had the problem since. Apparently they complete the ground circuits to the panel.

Check fuse #8! (I'm pretty sure it was #8--it was definitely a 15 amp fuse.)
 
I had a very similar problem with a 95 Grand Cherokee. It all started when turning off an overhead light. A relay near the passenger's feet was clicking rapidly when a door was open; radio worked intermittently; an aftermarket CD changer didn't work; info display in front of gear shift didn't work; interior lights blinked dimly, even when they should have been off; power door locks didn't work. The car drove fine, but the electrical system was going crazy. It turned out that this was all caused by one blown fuse.
 
Good luck!

Any resolution to your problems? I have 95 Jeep with similar problems- same clicking with door open, heater stuck on. I tried replacing 56006709 under the glove box but this didn't help. I can drive the car with the relay pulled- but radio, computer, HVAC don't work. HELP!!!

My problem persists, sounds very similar. I gave up on fixing it a year or so ago. I became convinced at that time that problem was not in the supply side of the electrical ckts, i.e., not the +12VDC side of things for which the fuses and relays play a role, but rather a bad ground connection somewhere. Only this could explain how so many things are messed up. Good luck!!

I bought a 1993 jeep cherokee country that doesnt run one day it wouldnt start it would crank over but wouldnt fire the man worked on it as a project with his son and it had weak spark when he got it so he replaced the sparkplugs, plug wires, distributer cap and coil and crank shaft postion sensor and it has strong spark and fuel but wont fire could it be spark timeing or are there any other sensors that could be messing with it starting.

'04 Grand Cherokee w/ 4.7 4wd - I have experience electrical issues that on the surface seem unrelated but are apparently tied together. Symptoms = windows on right side inop, elec door locks only work on drv side, speedometer is constant 10 mpg high at all speeds, interior lights inop. At one point the drv side windows went inop. I disconnected battery and drv function return but all other symptoms remained. i check PCI Bus and found the volt reading is varying between 0.5 and 2.5 volts which i'm told is normal. any ideas???

Check for loose grounds somewhere. I have had 3 problems with vehicles recently. I ended up cleaning ground connections on the battery or on the devices effected and have fixed 2 of 3 problems and seemed to help on the third one.

Ok last night my daughter pressed the overhead light in the rear of the console , after this happened a constant clicking of What I assume is the s.a.m. (system alarm module) relay. the radio does not work the interior lights flash the System information does not work.
 
I get up this morning to tackle the problem I started first with the Overhead console and removed it. The Light Assembly's were loose because a couple mountings were broken ( fixed with super glue and a small piece of jb weld, yep Jb weld works on plastic great), The backs of the light housing has wires on it that are exposed at the connectors and when the light was pressed it shorted out on the roof metal ( Used CardBoard and tape to cover the connections before replacing).
 
I found that the #8 fuse was blown (15A mini blade fuse) Replaced it with another 15a and the problem is fixed.
 
Hope this helps everyone who has this problem
