I need to know how to take out the accuartor on my air conditioner . Its under the dash .Help please

it could be several things could be the switch,also there is a flap in the dash that may not be opening,but if the compressor is kicking on and you are able to hook a gauge up to ensure you do have enough freon in the system this is a must try those things and let me know good luck!!!

Look for a vacuum line off or leaking start in the engine compartment than work your way under dash usually in engine compartment but could be under dash usually passenger side or on the back of control switch on dash.

Bad ground under the dash, no doubt. Check all of your chassis ground connections.

Does the compressor run ? If yes, you would need to know what the high and low pressure readings are to proceed.
It could be a blend door problem under the dash, or something else.

Looks like you checked all the things that need to be checked except "one." Sounds stupid, but did you check your temp switch on you dash to make sure it is the air conditioner you want to run instead of the heater? Sometimes, many forget this one simple check and can't figure out why the air conditioner won't engage.

You would need to know if the ac line is cold to each evaporator. Then if the blower motor for the front is getting power and ground. If the blower motor is running but no air is coming out the vents, you would need to check the blend doors under the dash.
It could be separate problems, or the PCM or ac control head on the dash.

under the dash
