Check the air vacuum motors or blend door actuators.

There were instructions on changing the fan, but I know that's not your problem.

It's the blend door actuator.

Not very good one to fix , somtimes cables that operate opening and closing of air vents bellow dash separate , and stop from opening , i think you will find most things under foot panels near passenger feet . and center consol near passenger feet . , you may need to take of those panels to see is you can visially see anything .

A/C fan stops completely (No Air) when accelerating.


The blower is probably running when you are accelerating, but you may not have air coming out the dash vents. If there is a vac leak in the HVAC the vent control will go back to the default setting which is defrost. You may not have enough vac to keep the blend doors on the vent setting when the engine is under load.

have your thermostat checked or remove it yourself car can run without it if it improves replace it with a new one these do sometimes get stuck ,if you do replace it always add antifreez to your water this also helps to keep your water and water jackets clean.

Increase cooling of A.C


With the A/C off and engine running and up to normal temp check the temperature at the dash vents at medium fan speed.It should be close to the outside air temp.If it's higher you have hot air from the heater leaking in the air stream to the dash vents.Next check the A/C system for a full charge...NOT OVER FILLED or UNDER CHARGED. Next check for air flow through the exterior of the condenser. ( in front of the rad.)The fan should run when the A/C compressor runs.These are the basics.
90% can be repaired with these items at 100%.

Hot air comes out of defrost vent at top dash and cold air out of


Hey, what setting is your A/C on Max AC? AC? Cycling air in vehicle or taking it from outside

The car icon on the right in this image is what I'm referring to when I say cycling air in vehicle.

Also, do you ever have cold air blowing? on any setting or any speed? if not, find your A/C fan, it is smaller the the engine cooling fan, sometimes there are 2 fans together. The AC fan should be located at the front of the vehicle and is usually electrically powered.

Also try to find your compressor, looks something like this:
730c4b9.jpg

is it running? is one pipe hot and one cold? (the pipes I am referring to are inlet and outlet pipes of the A/C compressor unit.)

Hope this helps, keep me posted
