Dodge Ram Truck 1500-2500-3500. Manual — part 452

BULB - A/C-HEAT CONTROL

WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental
restraint system before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact
sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative
(ground) cable, then wait two minutes for the system capacitor to discharge before performing further diag-
nosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the
proper precautions could result in accidental airbag deployment.

CAUTION: Always use the correct bulb size and type for replacement. An incorrect bulb size or type may
overheat and cause damage to the lamp, the socket and/or the lamp wiring.

NOTE: There may be minor variations in the locations of the bulb/bulb holder units on the back of the A/C-
heater control as a result of various optional A/C-heater control units. However, the bulb types and service
procedures are identical for all of these bulbs.

1. Align the bulb holder and bulb (2) with the keyed

opening in the circuit board of the A/C-heater con-
trol (1).

2. Insert the bulb holder and bulb straight into the cir-

cuit board until the bulb holder is firmly seated.

3. Using a small thin-bladed screwdriver, rotate the

bulb holder clockwise about 30 degrees on the cir-
cuit board to lock it into place.

4. Reinstall the center bezel onto the instrument

panel. (Refer to 23 - BODY/INSTRUMENT PANEL/
INSTRUMENT PANEL CENTER BEZEL - INSTAL-
LATION).

5. Reconnect the battery negative cable.
