I unfortunately discovered that the rear window defrost and side view mirror defrost button backlight bulbs (that are burnt out on my 2001 LC) are soldered into the circuit board. Certainly not the normal "pull the old one and plug in new one" replacement. I intend to order some bulbs, desolder the old ones, and solder in new ones. Has anyone ever done this on their LC? What size bulbs? T4 12 watt? T4 6 watt? Thx!
