The front heat is warm (what is coming out) but the blower does not blow. I have already replaced the blower motor and the resistor. Any other suggestions?

Hi bDUFFY,

You need to check the voltage power supply to the blower motor. It could be a bad fuse, power control relay or wiring fault.

Good morning

did you verify power to the relay from both fuses? The circuiy is a ground control. With the switch on, you should have power on both sides of the blower motor and you should have power at the blower resistor. The circuit is then grounded by the blower switch in the dash.
