tsb951411inoplamps.jpg TSB 94-09-12 Visor Screws
TSB 95-14-11 Dome Lamp Screws
Publication Date: JULY 17, 1995

LIGHT TRUCK:  1994-95 BRONCO, F SUPER DUTY, F-150-350 SERIES

ISSUE: Some customers may have concerns that the following features are inoperative:
* All courtesy lamps
* Map lamps
* Engine compartment lamp
* Glove compartment lamp
* Odometer in the instrument cluster
* Dome lamp
* Power mirrors
* Lighted vanity
* Cargo lamp
* Remote keyless entry

This is due to insufficient clearance between the outer roof panel of the cab and a map/dome lamp mounting screw, causing a short in Circuit 54, which causes Fuse 8 (15 amp) to become inoperative. This fuse protects the wiring for the above vehicle features.

ACTION: Replace existing dome mounting screws with new, shorter screws. Refer to the following procedure for service details.

BACKGROUND
Three (3) screws (52814-S36) are required to mount the map/dome lamp to the inner roof panel of the cab. Two (2) of the three (3) screws are used to complete two (2) electrical circuits, 53 and 54. Circuit 53 is after the lamp switches and is "cold" ("cold" means that 12 volts are not present) and Circuit 54 is before the lamp switches and is "hot" at all times ("hot" means that there are always 12 volts present).

The 52814-S36 screw is approximately 25.4mm (1") long. When there is a sufficient amount of downward force applied to the outer roof panel of the cab, the panel will make contact with the screw that has Circuit 54 (12 volts) on it. For example: When the brushes and dryer pass over the roof of the truck in a car wash or when traveling at highway speeds. As the roof panel contacts the screw, it causes a direct short-to-ground. When this occurs, Fuse 8 will be overloaded (15 amp), open and disable the listed features.

SERVICE PROCEDURE
1. Carefully pry pillar/dome lamp lens from interior lamp body.
2. Remove screws retaining interior lamp (map/dome) to roof trim panel.
3. Install new screws (52802-S36, 19mm).
NOTE:  ANOTHER OPTION WOULD BE TO REMOVE OLD SCREWS AND CUT/GRIND APPROXIMATELY 6.35mm (1/4") OFF THE END AND REINSTALL.
4. Reinstall pillar/dome lamp lens.
