Hello,

I have a 99 ram base model work truck with manual everything (locks, windows, side mirrors). I upgraded to power and heated tow mirrors and wanted to know if I switch out my temp control module with one that has a defroster button will it work to defrost my mirrors in the winter? Thanks in advance.

 

So long as everything is in place for them, should work just fine. Not sure what all is involved though.....

That said, the mirror defrosters on my 98 aren't real effective......
