For some reason, the left side marker lights on my 2000 Cherokee Sport are not working. At first I thought my tail light was out so I changed the bulb to find out it still wasn't working. So then I noticed the orange marker light in the front wasn't working either. My headlights, blinkers, and brake lights are all working fine. It's just the left side marker lights. Anyone have any idea or have this happen to them before?? I checked the wires and fuses and found nothing.

 

Fuse number 7. Just had the same problem on my 97.

 

Ok solved that problem. Now back to the problem I had before. Now both orange lights are steady on in the rear and neither of my blinkers or flashers work. This is the problem I had before, thought it just went away but must have been the fuse just blow. Weird because my blinkers worked fine when my left marker lights were out and the fuse was blown.

 

You have a bad ground which is cross shorting trough the turn signal circuit. Check all of the grounds around the tail lamps and at the front markers.

 

The hazard flasher went out on my 89. It was in the on position, causing the turn signals not to work. Not sure if this is possible on the newer models, but it's something to look into.

 

Yeah that happened to me as well. This is something different. The binkers and flashers work fine with the lights off. But when the lights are on, the orange lights in the rear are steady on, and when I turn my blinkers or flashers on nothing happens and the green arrow on the dash just comes on steady. weird.

 

Ok fuse keeps blowing and left side marker lights are not working again. Has to be a short or something grounding out.

 

My guess is you have single filament bulbs installed instead of the required dual-filament type.
