I have a 2003 Ford expedition Eddie Bauer. My air conditioner is not working. No air comes out of the front air vents at all. And the back vents come on but they make a clicking noise for a while sometimes goes away sometimes it doesnt. It just so happended to stop working during fire season, Had the air conditioner on while driving through ash. What could this be?

I first need to know if the AC compressor is cycling on and off.

Let me know.

If you look at the front of the ac compressor under the hood, you will see where the belt rides on the compressor pulley. Here is a picture:

Now if you notice, there is a pulley and inside the pulley is the clutch. With the AC off, the pulley will spin with the engine running and the center (clutch) will stay still and not move. When you turn the AC on, that center (clutch) will lock up with the pulley and begin spinning. That is what ment by the compressor running (cycling). It will run for awhile, then go off for a few seconds, then back on. That is the cycling part. Check that and let me know what it does, or if you have other questions.

If it is cycling, that tells me the system has freon and is working. Let it run and see if the lines from the compressor get cold. If they do, then we have a different problem. Chances are the blend door isn't opening. It determines if you get heat or AC inside the vehicle.

Let me know.

Ok so I found the compressor and it is cycling. It stays still with the pull moving when off and locks ups and spins when ac is on and cycles on and off. I did not know where those tubes are so I felt all the tubes around it and they did not feel cold to me.

If it is cycling, that means there is freon in the system and it is working. That leads me to what is called a blend air door. It is a door that determines if you have heat or AC coming into the vehicle. It is located near the heater core. If it isn't working, even though the AC is working, you will not get cold air.

Oh ok and that is why there is no air at all coming out of my front vents? Thanks for your help. Is that a fix I can do on my own? How much "should" this cost to fix?

Hi:
I just need to confirm one thing. Are you getting AC out of a different location other than the vents. For example, is it coming out the defroster or is there no cold air at all getting into the vehicle?

I just want to make sure before I answer.

Well I have not checked the defroster or the back vents, but I will check to see if cold air comes out, I know for sure that hot air comes out of the rear vents. All I know is that no air comes out of the front vents at all, not any.
