Hey everyone!
I have a friend helping with an install on our 06 Volvo XC90. Was just installing a new pioneer deck and four new speakers. After the install, the climate control doesn't work, and the driver door window controls do not work. Does anyone know why this might be? I believe the car has a amp...but I don't know much about this stuff...I am just trying to research what may be causing this problem. Please respond ASAP as we are in the middle of diagnosing this as we speak!
Thanks!!
