air conditioning by maumalien

I have an '07 EXPY. I noticed that
 my AC was working, occasionally. Then I noticed that my cold-hot gauge would drop to "c". When this would happen the air compressor would shut down and then the AC wouldn't blow out cold air. Then, for whatever reason, the gauge would be reading correctly and the air would resume. This eventually got to be where the guage wouldn't read at all then there was no cool air. I took this to the dealer and a local mechanic. Both said there was no correlation, but still no solution to the problem. THe local mechanic has replaced every thermostat that might be related, the accuator, flushed (or whatever) to the vacuum, but still no cold air, nor does the hot-cold guage work. The dealer has never seen this problem. Any suggestions?

Did you get a fix to this problem? My 03 is doing the exact same thing.
Thanks!

Rear a/c not blowing cold air by slick3299

I have a 1999 Eddie Bauer Expedition and the rear a/c is not blowing cold air. The front works great but the rear air is not cold MOST of the time. Every once in a while it may blow cold . Does anyone know what my problem is?

Vac leak? or Blaend Door? by mkabrick

One for the best of the best. My 97 expodition has issues.
 
When I first start the car I have good control to the hvac system hot and cold. After a while, when the car has warmed up OR with excessive RPMs things begin to change.
 
For example: A hot day. When I first start the car I've got good AC front and back. After driving a short distance you hear the noise, the distinct sound of an air damper closing (I call it sucking over). After it sucks over there is no going back to cold air. The rear a/c WILL still blow cold, but the front is hot as can be.
 
On a cold day when I need heat, the unit will blow cold until I can get it sucked over. I do this after the engine has warmed up by reving the RPMs, while the car is in first gear. Once it has sucked over there is no controll of the temp on the thermostat. It only blows HOT.
 
Oh yea one more thing, it idols rough. The thermostat knob is NOT digital.
 
I thought it was my blend door but now I'm begining to wonder if I have a vac leak.
 
PLEASE HELP.

The Expedition has an electronic blend door actuator. Vacuum controls where the air comes out but not the temperature. It sounds like your front blend door is going to the full hot position and staying there.

You may be low on charge so there is not enough charge to keep both evaporator cores cool.

The blower kept blowing, but at gradually lower volume and higher temperature after you had been driving for a while?
If so, your evaporator core was iced over. Turning off the A/C allowed the ice to melt and then it worked again.
 
Confirm if this sound like your issue.
