My heater and AC fans stopped working on all 4 speeds not just the typical 1-3. I've checked the fuses under the dash and they all seem fine. Does anyone have any suggestions on what to check for next?
The blower motor and the blower resistor are under the dash. It is under/behind your glovebox and near the outer kick panel.
The blower resistor has 1 electrical connector and 2 8mm screws holding it in place. The blower motor has 3 8mm screws and 1 electrical connection. The motor looks like your standard blower motor. You can put 12v battery power directly to the blower motor and see if it kicks on. Make sure you hold that sucker tight. It's got some kick. Obviously if it powers up, your blower motor isn't bad.
