Having problem boosting my 2002 buick lesabre

PWR WDO - 30amp circuit breaker , DRV -MDL 10amp fuse - both are located in the rear fuse box .
Fuse Block Rear
Under the left side of the rear passenger compartment seat

check fuse if good cluster bulb burn ,remove cluster instrument and change bulb that are burn

Its the large bulb.
The small bulb is the side marker bulb. The larger bulb (3057 or 3157) is the combo tail-stop-turn signal.
There is also a single filament bulb for the backup light.

Light is on because the system has detected a fault. A code read is needed to discover the nature of the fault and then after repair dedicated diagnostic equipment will be needed to clear the code.

Sometimes the airbag light will stay on when the passenger airbag is switched off, if it has that facility.

The actual problem might not be the airbag but the seatbelt pretensioners.

Check the switch

If the left turn is flashing fast then this is a sign that either the front or rear indicator bulb has blown and will need replacing once you have done this then you should find it will work properly if not post me a message back then i can assist you further ok

Rear tail lamps for the 2002 La Sabre has eight nuts that hold the cover in place ( one piece-all acroos the back of the car). Do not remove the nuts for the lock, the cover sits in place and is not secured to the lock. Use a 10 mm deep well socket. remove the nuts and lift the cover to replace the burned out bulb(s). The bulbs are #194 or #198 (very small bulbs), not the 3057. It is easy to locate the burned out bulbs by putting the car in reverse and shutting off the engine and then put the ignition key in the accessory mode. The lights will light unless they are burned out. Simply pull them out and replace with the new ones and put the cover back in place and secure the nuts.
