Electrical gremlins can be tough but I doubt this is your problem. I bet you have leaves or a nest of some kind in the fan area. Electrical parts, as anything man made, do go bad. If it only works sometimes, it is either the fan motor is needing replacment, a faulty wire or ground, or ..... leaves.

The a/c on my 2010 Mercury Milan quits blowing after about 2 hours of driving. Any ideas?


Sounds to me like the A/C clutch is no good and out of adjustment.You should goto your nerrest junkyard and get a used assembly take the clutch off then you learn how it comes off and install it on yours the save the pump for later use if needed. The clutch should only have a .010 air gap after install between th inner elctro magnet and the clutch plate it's self.

Car blows warm air when idling


It sounds like your AC unit could be overheating or even damaged.

AC units have a sensor that will turn them off automatically to prevent damage from overheating. If there is an insufficient amount of air flow, the unit will heat up, and then eventually turn off.

When the car is moving, more air is forced over the unit, likely keeping it cool enough to run, however, when the car come to a stop, it loses that air flow, and quickly heats up. Thus, the AC would work while the vehicle is in motion, and overheat and stop when the car is stopped and idling.

However, the AC unit could be completely blown. The cold air while moving could be just a case of air being forced into the car. Think of a house fan, the fast the wind blows on you, the cooler it gets.... Thus, it could be an illusion that the AC is working when car is in motion, when it really isn't.

Hope this helps.

Could be the flap that directs the air flow. Are you getting air flow to all vents? The flap is inside the venting and controlled by a vacuum operated actuator.

Vent in centre of windscreen not working i have a A4 1.8T 2002 the vent in the centre of the windscreen stopped working a week ago drove the car the next day was working perfect it has just stopped working...


There is only one door. Air flows through the AC evaporator and the blend door diverts some or all of the flow through the heater core. For heat, the compressor is off under electric control and the non-refrigerated air is diverted through the heater core. The door is on a vertical axis and can swing to any position based on random corner turns, fan speed, mode, etc.

When i switch on the ac, no air come out


Sounds like the blower fan is not coming on all the time. Also check for circulation.
For the fan, you have a resistor which not be be making a proper circuit for the fan to work. If the fan resistor is okay, then the blower motor is the problem.
If the vehicle has a cabin filter check to see if it is plugged. Good Luck!

Nissan 2000 ac hot when idle


the a/c condenser has a fan in front ( there is actually 2 fans if you sit on the car it will be fan on right side ) if this fan does not
come on immediately when you are parked and engine in idle
there is a problem with power to it, or motor failure. If you drive it
on the highway and a/c operates fine that's because air is circulating though condenser (thats what the fan is supposed to do at idle or slow traffic)

AC problem


We are going through the same problem, our ac stopped working about 3 yrs ago, we have had it checked out 3 times by different mechanics and they all scratch their head with no idea of the problem. We have no blower but you can feel a little heat and air coming out. We have been reading the boards and it appears this is a pretty common problem in these cars, along with a few other things I won't go into, we have heard the blower motor thermal resistor, we just replaced it, $20 at ford, did not fix the problem. Next we will try to replace the ac heater blower switch which involves removing the radio. This part is $66 at Ford but there also seems to be a blower motor switch that maybe different and cheaper, still checking out this. Let us know if you find an answer.
