I installed a new back window a few weeks back. The one I took out looks like it split from heat warping the seal. I rarely need to defog the back window I do have heated mirrors and like to clear the mirrors. Would like to install a switch so I can control the power to the rear window when the rear window defogger is pressed. I take it you can not just pull out the switch on the auto climate module? 
Could someone guide me on what wire I need to splice into to put a switch in to turn off the back window defroster?
