1996 Mercury Grand Marquis HVAC wiring diagram (auto control)
I have a 1996 Mercury Grand Marquis that I bought from my grandpa after my grandma passed. Since I've had it, the auto climate control unit randomly turns itself on. It would turn on on start up, even if shutoff before car is shut off. I would then turn it off again, and it would shortly turn itself back on. After a few times of this it would usually stay off. Sometimes it would randomly turn on while driving. Recently my blower motor stopped running, and the HVAC control does not turn itself on after starting the vehicle. Is it likely that this could be a related issue? Does anyone have access to the wiring diagram for this vehicle? Any help is greatly appreciated, thank you.
