6.4.3 - Module Repairs ( Brett Gadzinsky,  December 15, 2001 )

The modules are at each corner of the car, close to the lights. Trace the wires from the lights to the module. The modules have a metal cover over a plastic base plate. You need to straighten the bent tabs on the cover, then pull the cover off.

Inside you will find a main board, and maybe a smaller sub board that mounts on its connectors. The main board is held onto the base by four Phillips head screws at each corner. Remove the screws and then the main board.
Solder problem spots are the connectors between the sub board and the main solder both the main board pins and the sub board pins. A very close inspection of the solder joints may show rings around the joint where the solder cracked. Also resolder the relay joints on the main board.

Most of the joints on the little parts will be ok. Also check the relays inside...they operate the lights. If the module looks dirty inside, the relay contacts may also be dirty, and that will cause problems also.

The newer the car, the less problems you are likely to have inside the bulb fail modules.
