Sweet.So I was doing something today for about 5 hours or so.
My 01 tahoe has power mirrors with heat and courtesy lights, w/ power fold and turn signal. I purchased a set of dl3 power fold w/o courtesy light mirrors. Didn't like that they didn't have the courtesy lights, so I combined both mirrors to make one.
Now I have powered mirrors w/ power fold, turn signal, heat and courtesy lights.
