It may be the resistor for the blower motor. Unless you have already found the switch to be defective, it may be worth a look to see if the resistor is defective first. It will look like this;

1983 Chevrolet C10 Silverado: The AC compressor and heater blower motor fan will not come on.


The brown wire at the speed switch is the power wire. Powers is then directed to the blower motor resistor throught the orange, lt blue and yellows wires. The blower motor receives power through the orange wire. Check for power at the fuse with the key on. If there is no power the problem could be the ignition switch or the wiring in between the switch and the fuse block

My heater/blower fan will not shut off in my 2005 envoy even after my ignition is turned off and key is out, i've read a few similar problems on this, what is the solution and how much will it cos


Depending which HVAC system you have Manual (sliders for temperature) or Auto (digital readout), the control module is likely at fault. The Manual HVAC has a Resistor Module (which have a high failure rate) and the Auto HVAC uses an electronic module. Both of these are mounted next to the blower motor located behind the glovebox.

Heater fan not operating


Most of the time when a heater blower quits working it is the blower switch that fails rather than the motor. Blower switch can be accessed in the dash panel.

1993 dodge spirit heater fuse


The heater is NOT actuated by a fuse, the fan is. ]But if the fan blows, the electrical part is OK, then it must be the heater door that switches from the cold air to the hot one, or 2) the heater core is not receiving enough hot coolant.

Heat/AC Blower fan speed only works on High


Alot of people have the same problem with the fan switch and blown bulbs. There really is no fix for this. Jeep really screwed up when designing the heater control assembly. The cheapest solution is to buy another unit off Ebay. Can always go to the dealer but be ready to PAY for there mistakes.

Heater will not work


You have either blown a fuse or the fan simply doesn't work or the switch is bad on the dash.
1.  Check fuse 2. try and check fan , use diagnostics as described in manual, get online or from library or kragen 3. if fan works or tests good, might be dash issue, which will me dissassembly.
good luck
please vote on this solution.
