Heater/air conditioner motor

It could be either of those, but check the relay under-hood for corrosion as it may have some on it, then get it scanned because it would be the control unit in the dash.

Hi Cynthia,

Here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning. Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com. Once you have the codes please get back to us so that we can further assist you. Thank you for visiting 2CarPros.
