Ok it starts with hittin my brakes my gauge cluster lights turn on... then once i turn on my head lights my brake lights come on and today that stopped so i get in my jeep and turn on my head lights while the jeeps running and the starter turns.... but only when the jeeps running any ideas please!!!

 

Wow, starter cranks when you turn the lights on, that's almost comical, although I'm sure not to you.

Clearly you have a short or a bad ground somewhere's. I have spent the past 2 days running through electrical diagrams here: http://www.jeep4x4center.com/knowled...?utm_source=cj due to my own electrical gremlins. That page has all the diagrams for the entire system and some troubleshooting tips as well.

My first guess would be grounding issues causing components to follow a different path to ground when a switch is engaged like your key switch or brake switch etc.

This is where I am gonna to start on my rig tomorrow: https://www.cherokeeforum.com/f2/eng...130071/index2/ Post #20

Have you checked the relay box and fuse box? Sounds like things are getting crossed up somewhere maybe?

also X2 on checking all the grounds as a starting point if the relays/fuses are all OK.

 

all fuses and relays are ok thanks for the start guys!

 

Ok since it has been warm out I've had no problems, but when something gets wet it acts up again today the horn won't shut off and blower motor runs with key off...

 

Is relay is going nuts by the head light switch guessing its the blinker relay not sure though andY reason it will keep clicking and making noises .?

 

It's been a while but it was the fuse box and main harness going in it all corroded and pins broke off fuse box swapped the fuse box and harness and it fixed so many things dome lights cluster odometer horn glove box light door beeper, just wanted to let everyone know what it was

 

"Fuse Box". Are you talking about the Power Distribution Center (PDC) in the engine bay or the Junction Block (JB) in the passenger footwell?
