87 300E Auxilliary Fan Switch
Can anyone help?
I seem to have a bad auxilliary fan pressure switch because the fan does not run when the ac is on. I've checked the circuitry to the fan and it does in fact work, so I believe it's the switch. Can anyone tell me the duty cycle for the fan when the ac is on? Should the fan only run when the engine is idling or all the time or what?
