My brake lights won't turn off after a master cylinder and brake booster replacement. No matter what position I put that switch in, brake lights are on. And this looks way different than the OEM one shown on online parts websites. 1971 Cutlass Supreme.

 

That is an aftermarket switch. It looks to be chipped up.

 

Does the car have an add-on cruise control setup? It looks that switch has a vacuum port on it as well. Could be from a cruise control system that was added at some point.

 

I'm a dumbass, pretty sure that one is for CC. The actual normal brake light switch was just behind the AC ducting and popped out of its holder. Brake lights are off now. That's embarrassing lol

 

 

Now to fix the coolant leak that's getting into the floorboards. Prob heater core. Any tutorials on that one?

 

Grab a case of beer and start unbolting stuff on the right side!
