BULB - EVIC CONTROL
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) 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 diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental
airbag deployment.
NOTE: There are provisions for up to four bulb/bulb holder units on the Electronic Vehicle Information Center (EVIC) circuit board. The two
outboard bulbs illuminate the EVIC push buttons, while the two center bulbs illuminate the optional universal transmitter push buttons.
Therefore, the center bulb locations are only populated on vehicles equipped with the optional universal transmitter.
1. Disconnect and isolate the battery negative cable.
2. Remove the overhead console (1) from the headliner. See: Body and Frame/Interior Moulding / Trim/Console/Service and Repair/Overhead
Console/Removal .
3. Use a small thin-bladed screwdriver to rotate the bulb holder (3) counterclockwise about 30 degrees to unlock it from the keyed opening in the
Electronic Vehicle Information Center (EVIC) unit (2) circuit board.
4. Pull the bulb holder and bulb straight out of the circuit board.

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) 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 diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental
airbag deployment.
NOTE: There may be minor variations in the locations of the bulb/bulb holder units on the back of the single zone A/C-heater controls as a
result of various optional control units. However, the bulb types and service procedures are identical for each of these bulbs. The illumination
provisions for the dual zone A/C-heater controls are NOT serviceable.
