I have a new to me 04 1500hd crew cab lt..i kept my wrecked 02 1500hd crew cab lt..drivers seat in 04 needs element..i was intending to swap seat frm 02 driver side.(both trks are matched int/ext). I noticed 04 heated seat appears to functin different than 02..heated back and or bottom option on 04...pushbutton hi or lo only on 02. Will the 02 seat still function in the 04?
