Will K-Source Custom Towing Mirrors For 2004 GMC Sierra Add Heating Function

Question:

OK so over and over you realize that you’ll lose the power extension of the mirror. Over and over they say that you’ll have heated mirrors. But how? These trucks don’t have that option. So will the left right mirror or which when in the center position is what moves the old power extension function become the heater switch? Will you have to hold it down for it to work like the extension function? Over and over this isn’t explained. So help a trailer towing Dad out! ????

The K-Source Custom Extendable Towing Mirrors # KS62075-76G will not give you additional functions that the current mirrors on your 2004 GMC Sierra does not already have.

So nothing will become the heater switch since you don't already have it. The K-Source Custom Extendable Towing Mirrors # KS62075-76G are power adjustable and have the LED turn signal, but you'll only be able to use those if your current mirrors have those features.
