1993 Volvo 940 Q&A

1993 Volvo 940 Question: Brake lights are'nt working.

Brake lights are'nt working. Checked fuses, stop light switch, wires, etc. all ok. All other lights work as well. -
Answer 1
There is a bulb check relay in main fuse box, it's round and red. The brake light signal goes into that relay and comes out of it to the brake lights. Check the power in and power out when stepping on the brake pedal. I've seen these fail for just this reason, so that may be the issue. Good Luck! -
