if its is a aw4 automatic trans it is the trans range switch it is very expensive but rebuildable look orund on the net for a pic step by step rebulid procedure you basicaly clean the old grease out of it and repack it wit dielectric grease very simple hardest part is adjusting it just right
It is on the same circuit as the brake lights, but if they are not working, and the bulbs are good your switch needs cleaning or adjustment.
Attempt this first since the switch costs nearly $300 bucks.
On the passengers side of the trans just behind the bell housing there is a fan shaped switch, loosen the 12mm bolt ( smaller of the two, and rotate the switch while a friend checks the lights. this problem is usually accompanied by an occasional inability to start the vehicle, but can be cured by jiggling the shifter.
While adjusting the switch make sure that the vehicle will start in park as well, remember to block the wheels while testing the back up lights, engine off, key in run but not start, shifter in reverse, move switch until lights come on.
Once you find this spot, hold it in place and have your helper check to make sure it will start. This may take several tries to get both working correctly.
If you have no luck the switch may be dirty, this happens a lot. Hold the post to the bottom large bolt still while you loosen the nut, then remove it, then remove the 12mm adjusting bolt on top, remove the wire connector and pull the switch away, remove the bolts on the switch and separate the halves, use electrical contact cleaner and maybe some q-tips to clean all the copper connections completely apply di-electric grease and reassemble, refit to the trans and readjust so all functions work, this switch controls back up and start safety.
Caution! always hold that bottom bolt while tightening the large nut, this is connected to the gear adjuster and you could damage the internals if it isn't secured while you do it.

The headlight switch to the left of the steering wheel on the front of the dash acts as the dimmer. You spin the switch right or left depending on the intensity of the light you prefer.
The neutral/back up light switch is located on the passenger side of the transmission close to the rear corner of the housing. It is triangular in shape. Take it apart carefully and clean the contacts with contact cleaner.
