Hi, I just put new kool vue power heated mirrors on my 2001 2500 diesel. and threw the boxes away and lost the receipt. Drivers side power does not work. Does anyone know how to get the glass out so I can get to the wiring behind the glass. I know it's stupid not keep receipt I'll never do that again. forgot to mention these are flip up tow mirrors Thanks allot for any help I would hate to break the glass. Again, TIA
