Been wondering this myself. Metal base on the driver side is corroding under the paint, which I think is common. If I’m going to take the door cards off for the millionth time amd risk broken plastic to repair something, I’d like it to be an upgrade.

We didn’t order heated seats, but my 2002 4.4 came with the seat heat wiring in it and the LCI heated seats I swapped in work great. I’m hopeful that the folding mirrors were pre-wired too. I recall seeing a long mirror swap thread somewhere, but can’t find it now.

I would assume all LCI e53s have the wiring. RealOEM shows several mirror assemblies for my pre-LCI 4.4 and one mentions power folding. Pn 51167039925
