I once had this problem with another car I found out it was the ground wire of the car which is placed beside the motor on the left side. Replace it and it should fix our lights.
Check the pins inside the female connector. If you accidentally bent one over you may just need to straighten it out and plug the bulb back in.
on the ABS and brake light staying on, the float in the master cylinder could be stuck in one position, I had this on my 2000 caravan and that is what the problem was. .
could be headlight fuse or headlight switch.
Warped brake rotor. Have the rotors removed and trued or replaced. Replace the brake pads at the same time.
Brake vibration is usually caused by the brake rotors being warped. The rotors must be machined or replaced to correct the problem. if you can feel it in the steering then the drums are or rear rotor could be warped
If you have the same bulb for brake and signal, brake light power needs to be interrupted by the signal lights, The brake circuit has to go through the signal light switch so the problem could be there.
Check engine vacuum and power brake vacuum booster. If the brakes work but just require extra effort to stop, it's a brake boost problem.
Check the brake light switch. This can cause the brake lights to go out. There have been a couple of recalls on the 2001 for this exact problem. Contact your local VW dealer and have the switch replaced.
could be the the headlight switch, dimmer switch, headlight relay, or a problem with the wiring
Probably a brake light switch problem. May be able to adjust, or may need to replace. I just replaced the brake light switch in my 1998 Mazda Protege LX and the problem came back. I believe the cruise control could be shorting out the brake light switch.
First, check your brake fluid. That won't hurt anything. I don't have extensive knowledge on ABS, but I do know that the owners manual in your glove box says that this is an indication of a problem and to go see a dealer. P.S. If your brake fluid was low then that could be an indication that your brakes are due to be replaced. That could solve your problem, too.
The problem could be that your flasher switch is going out. I had the same problem on my 99 blazer. It sounded like a bee buzzing in my dashboard. Had the switch replaced and problem was gone. Hope this helps.
it may be your headlight switch, all mentioned circuits are routed through it
i have the same problem i replaced the coolant temp sensor to get my check engine light to go off but it could be a number of things the brake light means you have a problem with the brake system but i have hared that the light sticks and is a common problem with blazers in the late eighties and early nineties models
