Heat/Blower Not Working

There are normally 2 things that can cause this, a bad blower motor or a bad blower motor resistor. Since the battery was just replaced that adds some other possibilities, but no matter what, you'll need to have a shop check this out. Since the dealer just worked on it, I suggest you have them look at it, they should do this for little to no charge since they just worked on it, but that varies from business to business. Good Luck!

Recently had same problem. I found that the blower motor resistor was to blame, new part was 70.00 but i found that if you just take out the resistor and solder a new one it only cost 3.00 from radio shack
