Re: Brake Spring mystery
In case it matters - this car has only the one tail light and in there is only one bulb.
I appreciate all the comments. I have to (learn to) check for grounds and also get under that part of the car myself to see how that bake light switch operates and where that spring should go.
I did find one old post which may not be relevant to my situation (no answer jumps out), but it suggests the switch itself may benefit from maintenance.
