I have a 94 gmc seirra and the fan speed is controled by relays behind the glove compartment just pull the inside of the glove box it is mounted above the heater
where to find heater resistor 2004
could possibly be the blower motor resistor. which is generally located on the passenger side under the dashboard by the blower motor.
On a 1995 GMC Sierra, the fan resistor is typically located in the HVAC system, specifically near the blower motor. It is usually found under the dashboard on the passenger side, mounted to the heater box. Accessing it may require removing some trim or components for better visibility.
the heater fan resistor is located under glove box beside the fan blower.
It should be located on the evaporator case.
This can be caused either by the fuse or by a heater fan resistor located round to the rear of the dash somewhere around the center, further info can be sourced on this by searching google "E30 heater fan resistor". Hope this helps, B Paice
Its the fan blower resistor IMO...had this happen already. part is really cheap. Located behind glove box.
Location of 2007 heater blower Transistor resistor
It is located/accessed from the engine bay, passenger side of the firewall.
How do you replace the fan motor on a jeep cheerkie
under dash on passenger side inside the cab
