Compressor not working

low or no freon---- compression problem

You probably replace the wrong switch. I believe the high pressure switch is mounted in the back of the compressor. Pull the plug and jump it. If it works, replace the switch. I don't recommend you leave the jumper in the plug. If it the A/C pressure is to high, you could blow lines and such. Costing you a lot of money.

see this steps and think with clearly and logically NOT feared. God bless you
Start with the compressor. Does it engage when you turn on the A/C?
If so, the compressor is working and the A/C system probably contains enough refrigerant to make cold air, so the problem is inside the HVAC unit. Replace the motor that controls the blend air door (this is a difficult job and best left to a professional since it involves tearing apart the HVAC unit -- about an 8 to 10 hour job!).
If the compressor does not engage when you turn on the A/C, see if it will run by jumping the compressor clutch wire directly to the battery (use a fused jumper wire). If the compressor works when you jump it, and the A/C blows cold air, the system contains refrigerant and the fault is likely a bad A/C compressor clutch relay or a bad clutch cycling switch or pressure switch.
If the compressor does not engage when you jump it, the problem is a bad compressor clutch.
If the clutch engages but the compressor does not turn (the belt will start to slip and squeal), the compressor is locked up and you need a new compressor.
If the compressor clutch engages and turns the compressor, but the A/C still does not blow cold air, the system is probably low on refrigerant and needs to be recharged.

What do you mean when you say it wont shut off? is it blowing hot air or do you just feel a lite flow of hot air even if you have the settings to cold?

If this is the problem that you always feel hot air at low flow and the ac goes to hot air then i would say one of two things, first if you have the selector to cold and you feel hot air then there may be a problem with the blend door, this door move to allow hot or cold air, the door may be broken or just a bad motor that controls it. keep in mind if the ac system shuts down for any reason the air then will be warm, it will be about the same temp as outside and maybe a little hotter.

this problem almost sounds like the ac compressor shuts off and then you are getting the outside air which is hot, there are many reasons for the compressor to shut off, it could be the compressor clutch heating up and disengaging , this would be due to a bad compressor clutch.

another reason is the fans are not working, the best thing to do is when the system starts to blow warm check and see if the compressor is running, start engine and look at the front of compressor, with ac off the front of it will not move, and then with ac on the front will spin, check it out and let me know, if it blows warm air and ac is not working then it may be compressor problem but if you are getting warm air and the compressor is spinning then it may be a door problem.

This is hard to check with out testing the system, so i listed a few things to check and let me know the out come. also the ac blows cold for how long before it gets hot air blowing out of the vents, good day.

Is the compressor cutting out? It could be the compressor clutch relay is going bad.

It is most likely the compressor. When the A/C starts blowing warm, Check the power cable to the compressor. If it has power, it is the compressor. If not, you will have to check the system to see where the power loss is.

need to have a set of gauges on it and read the low side and high side to see if pump is weak that year compressor i think is on the bottom passenger side ,it is not a good desigh pump may be weak

When they refilled the refrigerant did they put die in it to check for leaks, it sounds like there may be a leak.

Either you are out of coolent or the compressor is not working.

First check the fuses, then lift the hood and have a friend turn the air on. The compressor should cycle, if not take it to a mechanic. If it does cycle you are low on freon, take it to a mechanic for a system charge. Make sure they check for leaks first.

your compressor might not work properly .....try to replace it
