The compressor won't turn on because there could be aÊproblem with the air conditioning system. You need to vacuum the system.Ê
The compressor wont turn if the freon levels are too low! It has a cutoff so if the freon all escapes the system the compressor wont be damaged.
Check the Freon pressure first. The AC compressor will not turn on if the Freon pressure is too low.
low on freon
most likely it is out of freon
If the A/C system is empty the compressor will not turn until you get enough refrigerant in it. Just turn on the A/C and hook up your can of freon. Once the freon starts filling the system the A/C clutch will engage.
It turns out that if there is no freon in the system, the computer puts out errors which in turn shut off the power to AC. Refill the freon and clear the errors either by tech or diconnect the batter for few minutes :) Learnin the hard way
Mabe your compressor is not kicking on for some reason. Check to see if the front of your compressor starts spinning when you turn it on. If it don't check to see if there is power to the wires that go to your compressor. If there is power you have a bad compressor. If there is not check the fuses or relays.
Adding refrigerant to a compressor is a precise job to take on, and it is important to know exactly what you are doing. Attaching the Freon kit, turn on the compressor, and adding the refrigerant are the steps to adding refrigerant to a compressor.
There is an ac relay, most likely mounted under the hood. There is also a low pressure switch, that will not turn the compressor on if the Freon is too low. Low Freon is the most common cause,
There are several things that can cause your air conditioning compressor to turn off after five seconds. The most common cause is a lack of Freon pressure. Check your air conditioning hoses for a leak.
The most likely reason the compressor is not coming on is because you are low on freon. The low pressure switch will keep the compressor from cycling on because damage to your compressor would result. You can jumper across the low presure switch with the engine running and A/C turned on, ( for short time only) this will provide you with question is my compressor clutch good, or am I just low on freon. The AC compressor relay switch may need to be replaced
turn car on and also the ac at full blast, under the hood you should notice some metal tubing to the left with a blue cap, take the blue cap off and connect the hose that come with a kit along with a freon bottle, fill until the indicator is at the green section.(if you don't turn on the car the compressor wont spin therefore the freon wont circulate)
