Re: Heater sandaly stop working ,
the fan it's correct...
So does the fan turn on or not and there is a blower moter resester you can check that controls the fan speed when you select on the switch its usualy mounted next to the fan.

The selector switch on the dash controls the blower motor relay, then the fan switch controls the speed. The fan switch gets power from a 40amp fuse and the control panel gets power from two other fuses. If you are working the control switch to get the fan to work, the control switch may be failing.
The wd40 will only work until you have 6" of snow & need some heat, then what
I would replace the blower motor & resistor pack
I like to tinker as you do, but only one time
I would suggest on the free side, you get a print from the local repair shop off of AllData & bring some donuts & coffee,that way you have your wiring diagrams
Hi
Check for bad connection at heater resistor or try tapping heater motor lightly
with ignition switch on and heater switch on. Could be heater switch connection.
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.
either blower motor resistor or blower selector switch.could be selector switch because if resistor was gone you should still have either hi or low fan speeds.
Check the following fuses:
10 amp GAUGE under the dash, and the 40 amp HEATER under the hood.
If both fuses are good, I suspect that you may either have a bad fan switch or a bad heater fan motor. The switches are rare to fail, I would suspect the heater motor first. Please try this: Turn the key on; turn the fan switch to high. Look under & behind the glovebox, for the bottom of the heater fan motor. Round thing with 3 screws holding it to the heater box. Using a small hammer, or something that you can tap with, tap on the bottom of the heater fan motor. You just may jar the motor enough to make it run. If it comes back on, you may need to replace it at some point in the near future. Worked for me quite a few times. Try that, repost to me what happens. Hope this helps.
heater fan does not respond to control. I tested the control switch, it is good. Fan motor is good it works with direct connection to battery. fuse is good. Can't find the problem. check the relay they are good checked the resistor it's good but no power the switch can you help thanks
