After Unplugging your ac check the opening of the front with something that you can slide inside the opening like a tooth brush. Do it gently.
There is a blower behind the opening. At times a lot of dust particles get stuck in the blower ( its like a long roller ). All you have to do is clean this blower with the brush.
If you could post the brand of your Ac, Type and capacity, It will be more helpful.
Generally its not difficult after you have seen it being done once.
Tell me if it works.
When there is a problem in the vent system it defaults to defrost setting. Check the doors & vac supply
yes
No power, no air! Simple
I have the same problem, and looking for answers. Please help!
Without testing a guess would be a blend door or actuator or maybe a control problem
first thing to check is the fuse
If central air conditioner turns on but is not blowing through the vents, check the filter. If it is dirty, change it. Change the thermostat into cool, this will defrost the air conditioner.
If the vents stop blowing when gas is applied, it is likely a vacuum problem. The vent system is controlled by vacuum, so when the engine is under load, there isn't enough vacuum to run the vents. How you test this is when the problem occurs, the fan will still be blowing air, however the flow of air will be out your window defrost vents at the top front of the dash. On a 1995 vehicle, it's likely just some of your vacuum lines are broken, and need replaced or repaired.
Check for a vacuum leak -sounds like it is starving for vacuum and reverts to the default position
Sounds like you have the beginnings of an a/c vacuum leak. Our Expedition did the same thing and eventually it defaulted to blowing out of only the heater vents, which is the default when things aren't routing properly.
I am sorry, I am not technical on this stuff, but we had the same problem on our 95 Mustang GT. We had to take it into the dealer and the problem was that one of the hoses had come loose, so it was not blowing enough air pressure to force the vents open.
2003 crown vic air conditioning vent dont blow
