CHaging signal light in a 96 Jeep Grand Cherokee

Another poster said it was the park/ neutral switch was melted and shorted.

My guess would be a problem with the turn signal switch.
Unless there is a short in one of the bulb sockets and the parking lights are flashing too.

are we talking blows a fuse or just turns off... if it just turns off then you might check your wires. you may have put the parking lights on the dash lights and not the parking lights connector....

check the rear brakes. Possible they are out of adjustment or worn shoes.

check wires from light receptacle to ground,may have been damaged.

I guess it would have been easier if I just mentioned the possibility of an element being burnt out, on a dual element bulb, and yes, it could happen on both.

front - 6.5" by 6.5" depth- 3"

in dash - 3.5" depth- 2"

back- 6.5" by 6.5" depth- 3"

Unfortunately, could not find owners manual for 1996.

There are two fuse boxes. One under driver compartment usually left to the steering colum. A label is stamp to identify each fuse. I would look at Park Lights and Instrument Cluster fuses. The easy way is to take a flashlight and look at all fuses. If they are all okay. Then just remove the Park Lights and Instrument Cluster fuse and reseat them. The other fuse box is under the hood and near the batter. It also has a label to identify each fuse.

the simple fix might be the park interlock cable. this locks the shifter unless you press and hold the brake pedal while selecting gears. I've seen and replaced a few of these on several chrysler/dodge vehicles.

check the headlight relays under the hood also fuses under the hood and in the interior fuse pannel.
