93 B2600i ex-cab 4x4 A/C intermittent operation

After calling the dealer back with the part number I found they have it ... but at $126.00 I'm not bitting. I briefly thought about opening it up now after your encouragement I'll do just that. This truck is a bitter sweet pill for me I've had only this model pickup for many many years( like 20 yrs 9 trucks total) and know that this will be my last one( no more good used ones and parts getting scarce) aside from those two capacitors on the ecu the rear end input shaft bearings clutch master and some minor stuff they are really bullet proof vehicles I really have abused them in every way imaginable and ( other than running out of gas) have never been left on the side of the road by one. Thank you guys for the feedback.

Wow, that's a lot of $$$, I see this as about $52 new http://parts.panamacitymazda.com/p/Mazda_1990_B2200/Switch--air-conditioning-ac/42724390/UB3961550.html?partner=googlebase_adwords&kwd=&origin=pla

That's why I advise trying to fix, and easy to check out to see if the fix works, don't even need to install it.
