I've had my driver side door panels off several times to tighten the mirrors and silence rattles, I guess I don't know what a regulator looks like. I've had the glass all the way out just to get at the mirror and greased and adjusted everything. Also, my electric door locks look to be flimsy mechanical linkage rods that have long ago had the wiring disconnected. The entire system looks poorly designed. Just my thoughts! I'll look for the regulator again, check my ground wires, and anything else I get tips on.
