I have a 2000 f150 5.4 4x4. The issue I am having is the heater and a/c blows air, but its very weak, if that makes sense to anyone. Not sure what to make of it and I don't see any threads for this problems. Any suggestions would be greatly appreciated.

So it doesn't blow faster when you turn the **** up?

I am having the same problem with my 98. However, I think your truck has a filter. It may be clogged.

Hi,
Ok. I found out it doesn't blow air at all. When I drive highway and play with the climate controls you can a slight breeze. I will check to see where this filter is and I m going to test blower motor(i think thats the problem).

If it's not blowing at all there is a relay under the dash beside the flasher relay.

Hi
Just wanted to send a update. I removed the blower motor and bench tested and it was not working. I replaced the blower motor. I also replaced the blower resistor only because there was so much rust on it and it would have gone back soon. Thanks for the help.
