question about low speed fan resistors
 

C/P from another thread on the turbo forum:

Can anyone tell me the function of the two small switches circled in red? They are only present on 86 cars which has the resistor packs inside the car, vs 87+ cars which had them under the hood. I'm repairing damaged wiring on my 86 that caused me to have to slow speed fans, but those small switches broke off the silver tray that holds the resistors. I'm wondering what their purpose is and if I can safely bypass them. I've been told they are thermal switches that will shutdown current to the resistor if they get too hot, but I'm trying to confirm that. Since my low speeds fans have never ever shut down on any of the 86 cars I've owned and later cars did away with them despite the resistors being in a location that i dont think would provide any additional cooling; it seems to me like if they are indeed thermal shutdown switches that it would be ok to bypass them. Can anyone comment further?

Doug, I don't know where you obtained the wiring diagram you posted but here's the wiring from the Workshop manual.

No small switches anywhere other than the main speed selector.

Oh, sorry. I thought you were talking about the cabin fresh air fan!! My bad.
