Question about 2004 Mercury Grand Marquis
I have a 2004 Mercury Grand Marquis. The vent function no longer works, i.e. won't blow air through the vent setting. Seems to be stuck in Defrost/floor setting. What do I do to repair it?
Manual or electronic heater/A/C controls?
Could be loose vacuum harness on back of control head. Need to put 10" tie straps on to hold it tight to control head.
