HEADLAMP DOOR OPERATION REPAIR DESCRIBED

MODELS/YEARS: 1986-88 TORONADO AND TROFEO MODELS

Toronado and Trofeo headlamp door operation can be affected as follows:

- Will not open - Binds or sticks while opening or closing - Noisy

The following items should be checked and repaired whenever any of the above comments are encountered.

1. The rubber boot covering the actuator manual knob should be checked for appropriate (approx. 3/8") clearance between the top of the boot and the knob. If the boot is down to far, movement of the knob will be restricted by friction from the boot. Also, if the boot is not down far enough or not straight, movement will be restricted by the sides of the boot against the side of the manual knob. Remove this boot, if necessary, to verify whether the condition is electrical or mechanical.

2. Check for electrical conditions concerning inoperative relays or fuses.

3. Conditions of noisy, binding, or headlight doors that hang-up can be caused by several items:

A. Doors hitting on the lower grille extension can be repaired, if the door is hitting on the inside corner, by shimming the lower portion of the grille forward. If the door is hitting on the outside corner, remove the cornering lamp and relocate the attaching screws to move the lamp forward. (Make sure the headlamp door is not warped. This condition would require replacement of the door.)

B. Contact can also be made between the actuator linkage and headlamp support brackets. Cycle the doors and watch for contact or look for signs of paint removal on the support.

C. Comments of excessive noise while operating the doors can be any of the above conditions as well as "dry" hinges. Make sure the actuator linkage and the hinges are lubricated.
