Dodge Caravan Climate control installation
I had a faulty Climate control and I had changed it for the 98 Grand Carvan. The new control unit works fine but every time I cut off the car, the buttons on the control unit are flashing for a good 30 min. The service guy at the dealer says that I need to do some module programming to check the other parts of the Hvac. Do realy I need to do that or is there any cheaper way to get it done!
