Headlamp Doors

The headlamp doors are designed to open when you turn the headlamps on and close when you turn the headlamps and park lamps off. The headlamp doors can remain opened without the headlamps being illuminated. By turning the headlamps on, then turning the headlamp switch to the PARK position the headlamp doors will remain open.

Battery voltage is constantly applied to the headlamp door control module from the LH HDLP DR fuse and from the RH HDLP DR fuse. When the headlamp switch is turned to the HEAD position, headlamp supply voltage and park lamps supply voltage is applied to the headlamp door control module. The headlamp door control module supplies battery voltage and a ground path to each headlamp door motor, opening the headlamp doors. When the headlamp switch is moved to the OFF position, the headlamp control module reverses polarity of the headlamp door motor circuits, closing the headlamp doors. The headlamp door control module will not close the doors if the park lamps are on. The headlamp control module is grounded by G 106.
