Bronco II 1986 airdoor control has cam controlled micro switch on bottom of lever pivot. My micro switch is broken and I think I have a source for a new one. one wire was attached Orange#14 what other wire do I need to complete this micro switch?
Thanks in advance for your response.

It's been awhile since I've pulled a control head out... but I remember cables. I don't remember any micro switches. Also I can't seem to find any micro switch in my EVTM either. The only electrical connections on the control head is for the blower motor and the is also an A/C control switch. The A/C switch has a BR/O wire and a LG/P at the connector.

I have the same diagrams, does't show my switch or wires. Micro switch has premade mount and looks like it belongs there.
Thanks

What is it's function?

Or what symptom are you trying to fix?

Don't know its function. Just finished swapping a 4.0 for the 2.9 and the 4.0 had a working AC so trying to get it hooked up.

Can you get a pic of said switch?

Same pic as Gumps but different:

Will try to attach what I have found. Appears this is part of a fitsall wiring harness. And switch is shown and not identified. as part of the rear window defrost circuit -- which I do not have.
Thanks for your help

The switch turns on components of the a/c system to help remove moisture from the air while on defrost. It’s only on a/c equipped vehicles and activated when defroster is selected.
