Checked fuses, all good. Not sure where heater motor is located. Can someone tell me where it's located so that I can change it? We get heat and the motor in the back works just not the one in the front so it's a pain in the butt to defrost. Any help is appreciated.

Welcome to 2CarPros.

Here are the directions for replacing the blower motor. However, before replacing it, I would check for power to it. The problem could be something other is bad. Also, you can provide power to it directly to see if it runs.

Let me know if this helps or if you have other questions. Also, make sure it doesn't only work on high speed. If it does, the resister is bad.

Take care,
