Look where the wires go to the lights underneath. Grab the white rubber piece that goes into the light housing and twist 1/4 turn. Then pull. The bulb just pushes into its terminal in the white rubber.

SOURCE: Have a 2002 Chevy Malibu LS with Cooper Lifeliner

the door tag says 30 PSI, with your tires i would suggest about 32 or 33 psi because they have a very soft sidewall.

99 GMC Sierra headlights & running lights won't work!


Headlights Circuit Description
The headlights are controlled by the body control module (BCM) via the AHL Relay when the headlamp and panel dimmer switch is the AUTO position. When in the AUTO mode, the BCM receives a signal, (voltage) from the ambient light sensor, based on the voltage of the signal of n the sensor the BCM turns the day time running lamp (DRL) lights OFF and the headlights ON. The headlights can also be turned on by placing the headlamp and panel dimmer switch in the head position.
The relay coil is fed by the headlamp and panel dimmer switch or the BCM and the battery B+ buss bar in the underhood bussed electrical center (UBEC). The BCM supplies current to the relay based on the input from the ambient light sensor via CKT 352.
The relay output feeds the LT HDLP and RT HDLP fuses to supply current to the low and high beam lamps on CKT 1340 and CKT 1240. The ground for both the low and high beam lamps is supplied via CKT 524 and CKT 525 to the dimmer switch. The dimmer switch uses CKT 1850 for a ground to G203.
Some circuits are monitored by the BCM, and upon failure may set a DTC.
Park/Side Marker and Tail Lamps
The park/side marker and tail lamps are split between the following 4 fuses:
?€¢
The FR PRK


?€¢
The LR PRK


?€¢
The RR PRK


?€¢
The TRL PRK

These fuses receive voltage from the park lamp relay. When the headlamp and panel dimmer switch is in the auto position, the body control module (BCM) controls the relay by grounding CKT 1080 based on the input of the ambient light sensor. The park LPS fuse supplies battery positive voltage (B+) to the relay at all times.
When the headlamp and panel dimmer switch is in the PARK position, the relay is by passed through the INT PRK fuse. Current flows from the PARK LPS fuse through the headlamp and panel dimmer switch to the INT PRK fuse in order to feed the following fuses:
?€¢
The FR PRK


?€¢
The LR PRK


?€¢
The RR PRK


?€¢
The TRL PRK

The license plate new bulbs fail to illuminate an the lift gate locks whenever closed...why?


This answer comes from BlazerForum.com (link is below) for a 2002 Trailblazer:

"It will be a 10a fuse in the under hood fuse box, labeled TRL PRK. If you have towed a trailer lately, and the fuse does not blow when you replace it, I would check the trailer that you used. If you have not towed a trailer, I would check the trailer wiring under the LR or the truck, to make sure none of that is shorting out. Good luck, Korey."

Rear park lights dont work every thing else does


The problem could be failure of the 10A INT PRK FUSE in the left I/P fuse block or the 10A PRK FUSES in the underhood fuse block.
