1993 Corsica No Heat But Air is Blowing
10-25-2008, 02:18 PM
My girls car is a 1993 corsica. A few months back the heater core went out so we replaced it. This was during the summer btw. Well now that the winter is here she turns on her heat but no heat comes out just room temperature air.
I have read a few things including checking out all the vac connections. I also read that you should bleed any air out of the system after you replace your heater core but not sure if that applies to 93's as the post was for a 96.

Grab the heater core input hose and output hose, and compare temperatures.
One hot, one cool, means no flow. 2 hot means duct door problems.
