I have a 97 dodge ram 2500 pickup. The defrost is not working, what could be the issue?
First Check the fuse, Then I would start with the switch, get a DC meter and see if it is making. If that's good there is a relay after the switch again check with the meter to see if the relay in making and breaking. if all that checks out then the heating element is no good...
Thank you I will try that
