2004 Ford Escape. AC blower motor replaced, but now getting no air flow?
Yesterday my AC stopped coming on. I turned the knob but couldn't hear anything working, and I was getting no air flow. I replaced the blower motor, using the same fan from the previous motor, and now I can hear the motor running perfectly, but i'm getting VERY little air flow. The air i'm getting is cold, but it's hardly anything. I checked the filter, and that's good. I'm unfamiliar with all of this, and the only paperwork in the box with the blower motor mentioned that motors can turn is different directions, and how to see which was the fan turned. There was very little information as to whether this was something I was supposed to do, or if it was just information, since there were no actual instructions. I read online that it could be the "blower doors?" not opening, but i'm unsure how to check this. The only door I saw was behind the glove box, and I don't know if that's the door being mentioned. Any assistance here is appreciated.
Try reversing the fan wires to make it rotate in the opposite direction
Most fan motors, if it's made for your particular vehicle come with the wires going to a plug, ready to plug n play. I had an issue in my van, you could hear the blower running but no air would come out of the vents. Sound familiar? The 'doors' in your heater box are vacuum controlled, either the vacuum directional switch inside the car is bad (unlikely) or the hose under the hood which supplies vacuum to that switch was vibrating against something and now it has a hole in it, fixed mine with a piece of electrical tape
Make sure you didn't disconnect a connection in the vents. Might reverse the wires on the motor.
You have either the motor running backwards, or the fan on backwards. You need to find out which way the old motor was turning.

- I replaced my PCM in a Ford escape and got new keys made, it worked. Now that PCM Broke and i'm trying to put the original PCM back in car? My PCM broke so i ordered a replacement PCM and Keys. I installed the replacement and it worked for a month and broke so I sent the replacemnet back. I had the original PCM repaired wile waiting foir the replacemnt to be shipped back to me. Now I can't get the original PCM to start. It is because i reprogrammed the keys to the replacement PCM. Or because I replaces the drivers in the original PCM it has to be reprogrammed or something?
