Okay, so I had the dealer fix the recall 3 months ago. I have never had an issue with the heat until after the dealer replaced the parts. The heat blower is now not worker. I just replaced the wiring harness and the resistor and still nothing. It doesn't seem like there is any power to where you plug in the new harness. I have checked all the fuses and they are all good. Any one have any ideas of what I could check next?

 

Let's start over from scratch lol.

There are a few test that can be done...
One is the resistor seated and brand new? Is the correct one?
Two is the harness seated/plugged in correctly?
Are there any signs of burn/blackened wires?
Three did you ohm each fuse that corresponds to hvac?
Four did you check any relays/circuits that are needed to complete correct function?
Five did you verify that you get power to the hvac controls?

Get back to us after thoroughly testing with digital multimeter.

 

relay? if so swap with a same type

you need to be looking at a wiring diagram and know how to check for 12v at the motor and resistors. you can ground any resistor or the motor side away from the 12v side.
there must be 12v on the motor wires.
