Question: rear defroster not working : check power to window ,no power told relay not working or switch. Changed relay did no good, Q how do you get switch out to change ????
Answer: If you are sure it is the switch, that is part of the air conditioning control assembly. It is not replaceable itself. You would need to replace the whole panel. To do that, remove the trim around it by carefully getting a small flat blade screwdriver around it to pop it loose working your way all the way around, then remove it. Then you can unbolt the control unit and replace it. Have not seen too many of these go bad though. Usually a wiring problem or a BCM gone bad.
