I bought my truck about 6 months ago and the driver's side heated mirror does not heat. Is this a common failure? Any way to repair it? I haven't been able to spend too much time looking at it, but all the obvious things are fine such as connections and fuses.

Any thoughts?

 

Just replaced mine on a 2001. Moparpartsamerica.com had the best price but I don't remember how much it was.
