Question type: Maintenance & Repair

I have a 2004 grand marquis with
automatic temperature control  that
erractically blows air, I have already
changed the blower resistor and

I've read able changing the speed

Check and see if there is a control valve in one of the heater hoses, if it does this might be bad. Also check the switch for the blower motor it might have a short.
