New here. This is for my dads car. He has a 93 as mentioned above. Just started having an issue with the motor blowing on full blast once the car is turned on. It will not shut off and there in no display in the climate control illuminated . None of the functions work . It blows without power to the controls it seems. Any ideas? Thanks

 

Probably the blower control module. I once had a '93 Concorde and it developed symptoms similar to what you described. At this point in time I have no idea where you might find a replacement part. You might start at rockauto.com or you might have to search junkyards. You'll have to find one off a car with automatic temperature control, like your dad's. The one's without ATC just have a set of resistors that won't be of any help.

 

So now it will work like it is supposed to and have power at the display and shut off etc , and then it will go back to blowing on high no matter what and no display power. Also where is the blower resistor located? Can it be accessed with out removing dash?
