Having problems with your 2004 GMC Yukon ?
I replaced the aux heater & a/c control module and both actuator doors in the rear of my vehicle, but when I turned the vehicle on both actuator doors over extended and now won't move or work. I took it to the dealer and they said the actuator doors are bad, so I got another set and the same thing happened. According to the dealer my control module is fine. What is the problem here? I can't afford to pay the dealer $1200 to install $300 worth of parts for me.
