no hear or air in my 2005 mercury grand marquis

Asked by Panthr Oct 12, 2017 at 08:31 PM about the 2005 Mercury Grand Marquis GS

Question type: Maintenance & Repair

For the last couple of years, the blower for my ac/heat control would only work on low or high. about 5 months ago, I had to replace the electronic fan, radiator and intake manifold (radiator went first, then the fan and then the intake). air wasn't working in the summer, but chalked it up to needing to refill the Freon,  which I didn't do. Now I turned my heat on for the first time today and it blows nothing but cool air. It does so on both a.c. and heat. Any idea of what it could be?

I would "burp" the radiator. There may be an air pocket.

Thanks. Turns out it's the heater control valve. and the a.c. is some sort of cellinoid. Forgot what he called it. a.c. is waiting till next year.
