The blower only works on high no mater what your trying to use ...ac/heater/vent/defrost. i have already replaced the HVAC blower control switch but it didnt change a thing.
Heres the electrical diag.....
Replace the blower motor resistor...The resistor limits voltage to the blower motor in all fan speeds except high...Good Luck!!
My 2008 Mercury Grand Marquis does not blow air. You can adjust the temperature, and you will feel cold air (or warm air) but the fan doesn't work. My mechanic is saying we need a whole new in-dash unit, ($600 dealer part) but I'm wondering and hoping if it's only the blower control module ($30) Any opinions?
