2005 chevy Tahoe 4WD. Recently replaced the brake master cylinder and hydroboost and BCM. got it all back together and now the brake lights are miswired somehow. with engine
off, the brake lights are always on, press the brake and they turn off, so it is behaving backwards. I replaced the brake switch and the wiring harness connector and no change. turn signals
, hazards, backup lamps all work normal, it is only the brake lights.
JA: Have you checked the brake fluid? How's the level and when was it last changed?
Customer: brake fluid is full and is brand new. new fluid went in with the new master cylinder. it is some kind of electrical problem.
JA: Are you fixing your Tahoe yourself? What have you tried so far?
Customer: yes I am. I replaced the brake switch and the wiring harness to it, but still brakes
lights always on, when the brake switch is depressed they turn off.
JA: Anything else you want the mechanic to know before I connect you?
Customer: i think that's it. thank you.
