Default Rear Load Door Power Contact (77 M&M Lifeliner)

Looking for a bit of advice....there is a spring loaded power contact switch which delivers 12+ (switched) to the exhaust fan mounted inside the rear load door. I have repaired it once (which lasted years) and I am sure I can fix it again...

BUT.... if I could replace it...I would be good with that too....

Just putting it out there in anyone has any advice...maybe one sitting on a shelf, manufacturers name ???

Mark

That looks like the switch that GM used on station wagons of the 1960's to deliver power to the back up lights, when the lights were mounted in the door.

Any contact switch would work. But the big problem is the power draw from the blower. A shim under it might be the answer to your problem To get more contack. Along with proper adjust ment on the door.

I would try Eds shim Idea first that is a common switch. Take a sample to a good auto parts store they may come up with one.

No the button one. it is the power contact that supplies power to the blower in the door

Do a search for street rod door jam contact switches. I think most are 2 but you might find a one contact style.

Thanks for the input...looks like I'll repair the old switch again....not a big deal...last fix lasted 15+ years...not like the rear loading door or the exhaust fan gets alot of use
