Passenger vans and cargo vans have 3 dome lamps which are in the following locations:

The cutaway models and the upfitter models have a single front dome lamp. The TR9 optional lighting package includes dome reading lamps, which are part of the dome lamp assembly. The dome lamps, including the optional dome reading lamps, have power from CTSY fuse 3 through CKT 40 (ORN).

Completion of a ground circuit operates the dome lamps. The dome lamps have ground by the dome lamp switch, which is part of the instrument panel (IP) dimmer switch, through CKT 156 (WHT). The dome lamps also have ground by either the illuminated entry module or by the optional remote control door lock receiver. Refer to Illuminated Entry and Keyless Entry below for a descriptions of lamp operation by the illuminated entry module or by the remote control door lock receiver.

When equipped, a dome reading lamp is on either side of each dome light. Push-button switches operate the dome reading lamp bulbs. Depressing the push-button switch once connects the associated dome reading lamp bulb to a local mechanical ground. Then the bulb lights. Depressing the switch again opens the ground connection.

The TR9 optional lighting package provides stepwell lamps. The passenger vans and cargo vans have stepwell lamps at the following locations:

The cutaway model and the upfitter models do not have the stepwell lamp for the side door. CTSY fuse 3 powers at all times the stepwell lamps through CKT 40 (ORN). As with the dome lamps the stepwell lamps have ground through the dome lamp switch and either the illuminated entry module, or the optional remote control door lock receiver.

The left front door and the right front door power side window switch lamps receive power with the parking lamps from PARK LPS fuse 9 through the park lamps switch contacts of the headlamp switch. CKT 9 (BRN) delivers the operating voltage to the lamps when the headlamps or the parking lamps are in operation. The lamps have ground by CKT 150 (BLK) at ground 201, or at ground G200 (upfitter provisions).

The left front door and the right front door power door lock window switch lamps receive power from PARK LPS fuse 9 through the park lamps switch contacts of the headlamp switch. CKT 9 (BRN) delivers the operating voltage to the lamps when the headlamps or the parking lamps are in operation. The lamps have ground by CKT 150 (BLK) at ground 201, or at ground G200 (upfitter provisions).

The optional sun shade mirror lamps are in both the passenger sun shade and the driver sun shade. A lamp is on each side of the sun shade mirror. Voltage is available at all times to each sun shade from CTSY fuse 3 through CKT 40 (BRN). CKT 150 (BLK) to ground G201 provides ground. Opening the mirror cover operates an internal switch. The internal switch operates both lamps at the mirror. A local rheostat controls the brightness of both lamps.

All of the vehicles have an IP compartment lamp. A local switch which closes contacts whenever the compartment opens operates the IP compartment lamp. The lamp switch has power at all times from CTSY fuse 3 through CKT 40 (BRN). The lamp has ground by CKT 150 (BLK) at ground G201.

All of the vehicles have an ashtray lamp. The ashtray lamp lights when the parking lamps are in operation. Voltage is available from CKT 9 (BRN) from the headlamp switch. When the headlamp switch is in the park lamps position or in the headlamps position, voltage is available from PARK LPS fuse 9. The lamp has ground by CKT 150 (BLK) at ground G201.

All of the models have an underhood lamp. The TR9 optional lighting package provides an underhood reel lamp. The underhood lamp and the optional underhood reel lamp have power at all times from the HORN fuse through CKT 740 (ORN). The lamps have ground at ground G103 by CKT 150 (BLK).

An internal switch operates the underhood lamp. The internal switch is responsive to level. When the hood is closed, the switch contacts are open. When the hood is raised, the switch responds to the change in orientation. Then the switch contacts close.

The underhood reel lamp has a local ON-OFF switch for the lamp control. The reel lamp has a PUSH latch which, when the latch is pulled out, releases the lamp head. Pull out the lamp from the reel in order to use the lamp anywhere in the general area. After completion of the use of the lamp, use the RETRACT handle in order to rewind the reel's cord on the reel.

All of the vehicles which do not use the remote keyless entry use the illuminated entry module. The illuminated entry module provides for a delayed turn-off of the dome lamps and the stepwell lamps after the closure of the last door. After the last door closes, the module keeps the lights illuminated until either the internal timer times out, or the ignition switch moves into the START position or into the RUN position.

The illuminated entry module receives operating voltage at all time from the POWER ACCY fuse A through CKT 540 (ORN). The module has ground at ground G201 through CKT 150 (BLK).

The module senses that a door is open by a ground input on CKT 157 (GRY). The module senses the ground input only when the dome lamp defeat push-button switch is not in the depressed position. When push-button is in the retracted position, or the out position, contacts close in order to connect CKT 328 (PPL) from the door jamb switches to CKT 157 (GRY).

CKT 328 (PPL) from the dome lamp defeat switch connects to each of the vehicle's door jamb switches. The left front door jamb switch and the right from door jamb switch are standard for all of the models. The side door jamb switch and the rear door jamb switch are not available on the cutaway models or the upfitter models. When the associated door is open, the jamb switch contacts close in order to connect CKT 328 (PPL) to ground. The left front door jamb switch and the right front door jamb switch have ground in CKT 150 (BLK) to ground G201 or to ground G200 (upfitter provisions). The side door jamb switch has ground in CKT 150 (BLK) to ground G402. The rear door jamb switch has ground in CKT 250 (BLK) to ground G401.

When an open door condition is present, the illuminated entry module closes the internal contact equivalents which connect CKT 156 (WHT) from the lamps to ground G201. This action occurs immediately. When all of the doors close, the grounded wire of CKT 157 (GRY) loses input. However, the module maintains the internal contacts closed for several seconds. When the ignition switch moves to the RUN position or the START position while the lamps are illuminated, the internal contacts immediately open in order to extinguish the lamps. The signal that the ignition switch is in the RUN position or in the START position is from GAUGES fuse 4 through CKT 39 (PNK).

The remote control door lock receiver replaces the illuminated entry module for vehicles equipped with remote keyless entry. The remote control door lock receiver provides the lamps-off delay when all of the doors close, as described in Illuminated Entry Module above. The remote control door lock receiver also turns on the dome lamps and the optional stepwell lamps when the vehicle's doors unlock remotely. the lamps remain lighted for approximately 40 seconds or until the ignition switch is in the RUN position or in the START position.

The remote control door lock receiver has voltage available at all times from the PWR ACCY fuse A through CKT 540 (ORN). The remote control door lock receiver has ground by CKT 150 (BLK) at ground G201 or ground G200 (upfitter provisions). The remaining interior lighting circuits operate in the same manner as the illuminated entry module.
