1999 taurus electrical problems
I have a 1999 Ford Taurus and sometimes the air conditioning abruptly changes to heat and the blower suddenly goes to high. This car has air conditioning with electronic automatic temperature control. Also, the cruise control will not set - the cruise indicator light blinks when the set-button is pushed. Also, the door-ajar light stays on and the doors will lock but immediately unlock, and the dome light stays on too. Any ideas about what is causing the problems described above?
