Are all power mirrors heated? I have power mirrors but they aren't heating up. Can I put heated mirrors on this very easily? BTW 97 4x4, auto, 2500.

 

Not all power mirrors are heated.
To be heated you have to buy heated mirrors which are sort of pricey unless you get them from the junkyard.
Not all that hard to hook up, just one more wire from the dash area to the mirrors and a switch. The stock heated mirrors go though a timer so they don't stay on too long and cause damage like melting plastic.
