My jeep cherokee limited. My parking lights and tail lights dont work. My head lights work and my brake lights work. Everytime a put a 15 amp fuse in the fuse box marked parking lights the fuse blows. Where do I start looking for the problem and how do I fix it? Thanks

See my profile. Imma CJ Guy.I do not know specifics about your rig.

It sounds like you have a short.

It may be EZ to fix. Or Not!

My approach would be remove the bulbs to the front end (all that burn when park lights are on. Sidemarkers too). Install fuse. If it blows. Reinstall the bulbs.

Then do the same for the rear. Install fuseBlow or not?

Should Either FRONT OR REAR. NOT BLOW THE FUSE. Install the bulbs one at a time, with PARK LIGHTS ON. Till you blow the fuse

Am I speaking Greek above?

Investigate that circuit (the wires for that particular light) for a short

I hope you just come across a bulb that is maybe installed incorrectly.

On CJs sometimes the socket, itself falls apart inside causing a short (below the contacts you can see). The test above. With the bulbs out, MAY or MAY NOT expose a bad socket.

If you have a TOWING PIGTAIL insure it is not poorly taped up and rubbing something.

Gimme some good news, that it was EZ!
