I have a 2004 Dakota with the 4.7. The heater quit working and only worked when it was set to high. Now it does not work at all. Any ideas on what could resolve this issue?

Thanks in advance!

 

First check fusees. Next check the blower motor resistor pack. On 1st Gens it is on the passenger side of the firewall. I don't know if 2nd Gens is in the same place. If you have to check the stickys at the top of this section for the factory service manual.

 

I put in a new blower motor resistor and it works fine now. Thanks!
