2000 Ford Taurus Heater / AC / Fan blows weak

Is the air flow coming out of any vents that it shouldn't be. Have you checked up under the dash on the passenger side at the air intake to make sure you didn't suck a plastic bag or anything like that up the intake? Do you have a shedding pet that rides in the car often?

Thanks for responding, Wrenchtech. In response to your questions:

I don't have anything that sheds that rides in the car.

I checked the air intake area and it seemed clear. I tried floating a plastic straw wrapper up near the fan and it *would* have been sucked in if I let it. The air intake seemed strong.

The vents seem to behave as expected when the control knob is adjusted.

However, as I thought about your questions "is there air coming from where it shouldn't be" I noticed that I WAS feeling some air on my leg nearest the console. When I got up underneath it seems there is some air leaking from behind the dash where there is a foam "gasket" that is not sealing as well as it probably should be. I did my best to seal it with some gorilla tape (high tech, I know) and while that seemed to seal up most of the leak it didn't really make the air flow from the vents much stronger.

I suppose there could be other leaks like this but I don't know where. Any other suggestions in general?

Thanks again!

There is a small plastic vacuum line that comes through the firewall. Double check that for any leaks. Tak a random vacuum reading along it somewhere and it should match engine vacuum. If it doesn't, you are leaking somewhere. That plastic line can be cut and spliced using a little piece of rubber vacuum hose the correct size.

Wrench, I've read your PM however I can't reply to it-unable to send it-user/pass is not cooperating-He loves his Jeeps

Got it. Drop me a PM when you get it working.
