My cherokee recently started blowing fuse #2 Radio/Cigar Lighter. This morning I drove it with no problem. I drove it this afternoon replaced the fuse, blew it out again, replaced the relay and fuse, blew it out again. Its the accesory power to my radio, clock, and cigar lighter.

Could it be my ignition switch? I already pulled all of the electronics out to see if that fixed it and no dice. Any advice would be appreciated.

 

did you pull the lighter too?
first thing I would look at. Lots of potential for shorting out

 

There is nothing connected to that fuse. Only ACC is out also. Just blows the fuse as soon as you turn the key.

 

by pulling out the electronics you mean what?

 

I disconnected every electronic on that circuit. Radio, cigar lighter, clock, CB radio everything. They are not even on the dash board any longer.

 

you removed the cig lighter or did you also un plug the socket also

 

which fuse panel are you refering to inside or out side

 

The inside fuse panel. The cig lighter is disconnected.

 

Almost a year ago I installed anew head unit in my explorer ( I know not a Jeep) but when I installed it some wires became exposed and touched meatballs which then proceded to to shut of my dash lights and accessories. Didn't know why for a day. Then took my head unit out and everything came back on and reinstalled properly. I'd check for some exposed wires. Hope that helps!

 

I meant metal not meatballs.

 

wiring is the most time consuming thing in auto repair what about the fuse box pull it and check the area whe fuse 2 is for problems other than that its follow the wires untill you find the proble has there been any thing been added or changed right b4 this started

 

I have done a lot of things to this jeep but no it just randomly stopped working. The electronics were all screwed up from PO being a dummy. Fuse block was hit with a freaking hammer I think and some of the tabs are broken. All of the fuses were mashed in place, cracked plastic, small fire behind the heater control box melted some wiring. Basically this jeep is an electrical NIGHTMARE.

 

it sounds like u have a short to ground some where just trace the wires back to the fuse box and replace the broken wire or just tape it up

 

When you say heater control box, are you meaning the controls right below the stereo? if so the radio wires go thru the same harness in the back of the dash, if i remember correctly. u more then likely have a wire that is grounding out in that harness.

 

Have you thought about just buying a new harness and replacing the whole thing since it sounds like it is a mess and you are just going to have more issues down the road?
