I have a problem with a 93 Jeep Cherokee Laredo 4W - The right blinker & brake light works like they should. However,the left brake & backup lights are out ( new bulbs have been installed & still out). When I use the left turn signal it looks like emergency flashers are on in the back. The front of the vehicle looks normal. What could the problem be?

Any ABS Light on dash?

I'd start with a new flasher relay (they're cheap). If not that, then go to those lamp sockets and check for corrosion. I had issues similar w my 95 laredo...it was the flasher.

I would suggest that it could be the flasher as I had a similar thing happen on my motor cycle. If it does not work at least flashers are cheap.

Don't know if this will help but its how i fixed my 2001.

Trouble shoot wires there is a break somewhere and its touching metal hope this help.

could be the brake switch went out of it

the problem is the metal contacts inside the lense itself,the socket make contact with the little metal tabs, bent mine out a hair or 2 ,and never had another problem with the brake light not working on my drivers side.

Try the hazard switch.Do all the blinkers work?This may be a loose connection to the lamp.The window and lock system are on seperate circuits so very unlikely they are related.There is a seperate relay for the blinker and hazards,so a single blinker not working is either bulb or wiring.Widows are operated by motor so check the fuse, wires and and actuating switch. (Door trims off).Also check its not just jammed.Locks,check fuses,switch wires for damage or looseness and the actuator is working.Check the actu. rods are not loose are bent.(need the door trims off for this).Quite a few different things but hope this helps

There could be a fusible link under the hood off the starter relay that is burnt out.
