Fan Speed Switch

[1990]

Anybody have problems? I only have 3 speeds. The forth has quit working for some reason.

Its either the switch or the resistor. Pull out the resistor and look for a break in the coiled wires.

Okay. I'll check that out when i get a chance to take out the dash.

Well I don't know about your 90 but on my 93 I found it behind the glove box in the fire wall

The switch in my 92 was burned out. The spade was actually burnt out of the switch. Usually when the resistor fries, its the lower speeds that quit. My wifes Jeep has ate 2 of them due to mouse nests in the heater.
