Blower motor is located under the hood on the passenger side. You should be able to check for voltage at the plug on the blower motor. Voltage should vary according to the speed that your switch is on.(High, Med, low). I believe the wire is black or purple that connects to the blower motor with a rubber grommet on the end. If wire looks burnt or rubber is melted, my guess is that the motor won't ohm out and is burnt up as well.

Verify you have good power and ground at the blower motor if so replace and make sure the wires are not routed near the blower motor.

Heater does not work


Check heater fuse.
If fuse good - could be a failure of the blower fan motor or blower control switch.
If fuse bad - bad blower fan motor could have blown the fuse.
DO: check fuse, then blower motor.
Pricing: new blower motor: Duralast PM270 $43.99
new heater control switch: Duralast SW229 $46.99 (without
A/C).
I'd expect your blower resistor to be good - when they fail, the blower only will work on HIGH setting.

Fan blower does not turn on I replaced blower, resistor and even a relay but does not work. So I ran a power wire from battery to resistor and it works what can be the problem?


The heater control,where you turn it on,and off,pull it out,it is most likely burned up where the connector attaches to the switch,and the connector,will most likely have to be replaced.

No power to the heater controls


Well i would check the fuse if you didn't disconnect the battery while you replaced the blower motor. if that's ok make sure you connected the blower motor correctly. If all else fails it is possible you may have damaged the wiring or connectors
