Rear brake lights work but rear driving lights wont on a 1994 buick lesabre

the rear bulbs are two filament bulbs one for driving lights or park lights and one filament for signals and brake lights. check the bulbs and sockets for proper operation

Step on brake pedal and see if you have brake lights. The brake light switch release the solenoid to let it shift. If brakes lights work then the solenoid could be defective. Also the fuses should be checked for the brake lights if they don't work.

Right rear wheel may have worn out or damaged brake pads or rotor...You should be able to spin this wheel freely when off of the ground...if not brake parts, then the wheel bearing is bad...(locking up) Hope this helps.

Look for a bleeder on ABS HCU unit- the one with brake tubing

Drive it & then Bleed again

Have to hear the abs pump come on,check fuse for it

If that doesn't work may have to open the
hcu with an obd1 scan tool & bleed

Locate where your abs sensor is and clean it this might do the trick.I have a ford F150 this does the trick just to clean it

even tho the e-brake might be off or seems off, you might have a bad switch on the ebrake that is making the light go on and off... so you might have to have the switch replaced....hope this helps

I don't know if this works on a Buick but I have had two cars that the auto adjusters worked when you used the parking brake, I rarely use the parking brake so I got in the habit of working the parking brake 20 times or so at oil change time.

check to make sure that all the the bulbs in the rear are working,even the third light

Since this is happening only to one side of the vehicle and not the other than i would say you have an electrical fault in the switch and or a hot wire is broken not allowing your lights on that side to come on when told to do so.
