'72 door plunger swtich

[Jerome P.]

The plunger switch seams to not extend (spring out) out all the way when the door is fully opened. Thus the interior courtesy lights fail to come on. I can gently wiggle the plunger and/or gently pull on the plunger, and the lights come on. The next time the door is opened same thing no lights until I move the plunger.

Opinion: obviously, I have a poor connection. Short of replacing the switch or checking the wire connect, is there any problem with spraying the unit with some CRC's - Lectra-Motive Electric Parts Spray Cleaner or similar to lubricate and clean the plunger and hopefully remedy my problem.

Your thoughts.

There's no problem with doing what you suggest but I don't think it will solve the problem. More likely, the shaft of the switch has become slightly bent or distorted.

I had the same issue. I used contact spray and it has been working ever since.
