Thumbs up Re: Digital Heater Motor blower Resister

Casper's Electronics has the solution, as has been posted. It is improved from the OEM unit so as not to fail again.

Before you spend the big bucks on that module, make sure it's actually the problem.

I just went through this with mine. I also thought that module went bad because when it does, not only does the blower quit but the A/C compressor also wont work.

I thought it was fried.

After some troubleshooting, I determined that there was no 12v getting to the module, via the big fat red wire. It's supposed to be constant hot.
Check that. If the 12v is missing or low or flaky, follow that wire, it runs over by the fender and comes out of a multi pin UNPROTECTED connector that just happens to be sitting in the worst possible place. Right where water drains down between the hood and fender and getting it wet. Causing corrosion.

I had to run a new hot wire around that connector to supply the 12v to the module.

Lesson learned. Troubleshoot voltages before spending on something that may not be needed.
