My AC Compressor wont kick on. I have the proper amont of freon

My AC Compressor wont kick on. I have the proper amount of 134a freon, but I only works when I put a jumper in the low side switch. Then the compressor will turn on on. My compressor USED to turn on by its self recently, but not now.

Will no freon prevent me from adding freon if the compressor wont engage without it


Sort of.
If the system is empty, you would need to jumper the low pressure switch to power the ac clutch to put the first can or two of freon in.
Keep in mind the system is supposed to be vacuumed out before adding freon, so if it is full of air you won't be able to put the full amount of gas in.

The car has a specific amount of Refrigerant in the lines and does need time to warm up to begin the cycle on and off so make sure you have the proper amount of refrigerant and give the compressor time to kick in

First thing is have the AC charge checked by a shop, if that is OK then the AC compressor low side pressure switch may be defective or the compressor relay is defective.

Ac clutch not kicking on


ADD Freon. It's a R134 system and the pressure is too low. Trust me add Freon and it will work fine. With a low amount of Freon if you jump the low pressure switch at the accumulator it will be very cold but will not have enough pressure to kick on the low pressure switch.

AC not running in my 1998 Jeep Cherokee. Changed AC clutch compressor RELAY, freon level is good, temperature sending unit replaced along with cooling fan! Checked all fuses still good. Can't seem to...


Hello, You have two switches which work off the pressure of the Freon. Both of these switches cut off the power to the compressor. One is for HIGH pressure and the other is for LOW pressure. Check for power at the compressor clutch connector harness while the controls are set and the engine is running. You may have power and a bad clutch.

When you say that the Freon pressure is good, does that mean the pressure is within the proper range? Too much Freon will make the HIGH switch cut off power and too little will make the LOW pressure switch cut off power.

The ideal amount(ozs) of Freon is what is recommended by the Manufactuer and it will provide a moderate amount of pressure of about 35psi-40psi. You can borrow pressure gauges, called Manifold gauges to measure your system at autoparts stores with loaner programs.

The low pressure side of the system is the one you use to induce the Freon to go into an empty system. You can bypass this switch by taking off the connector and putting a "U" shaped jumper into the harness and the compressor clutch should get power to LOCK up all of the time.

You can take off the switch connector at the compressor clutch and then check for power when bypassing the HIGH pressure switch if the LOW pressure switch does not make the system get power. Only, really only bypass the HIGH pressure switch with the clutch connector disconnected. The HIGH switch is there to prevent damage to all of the components from seals to lines to every piece of Freon hardware in the car. Bypassing with the A/C clutch disconnected will allow you to know if power is getting to the compressor clutch.

Finally, you can get FREE wiring and fusebox diagrams through Autozone.com. Just sign and register to their site and then you can print the documents for yourself.

Good luck with this repair and I hope my solution helps you.

On my BMW 325XI Wagon, the ac is not cooling, the drier, expansion valve, compressor & ac control module have been replaced. Starts to cool as low as 65 degrees & then compressor shuts off.


sounds like unproper ac evacuation before charging the freon to your ac system. do a proper evacuetion to the system check the ac compressor oil charge the proper freon & amount check the vehicle tag for the amount of freon under the wood close to the radiator

Air conditioner starts blowing cold air then blows warm


This is most likely the cycling of the AC unit. As the compressor pressurizes the 134a Freon you get the cold air, once it reaches a certain pressure it cuts out. If you are low on Freon it will cycle out more often. Check your freon level with a gauge to see if your within the proper tolerance. If the compressor runs for a period and doesn't reach the right pressure it will cut out to keep from damaging your compressor so it is important to keep the correct amount of freon in the system.

A/C compressor kicks on and then immediately kicks off. We were trying to add freon and the pressure went way up. I stopped, but the compressor won't stay on now.


ur high pressure switch is kicking ur compressor off,legally by law u need to have ur system evacuated then re charged,, u cant put any more in if system is full,,,u have to let some out,,how u do that is up to u,,u should find out how much the system holds,,sometimes there is a 134a\c sticker under hood or on passenger side strut tower that will tell u,,,drain it completely,,then ad the proper amount,,,,hope it helped,,

AC has freon (134a) pressure is good. Compressor


Have a code reader or scanner put on the car to erase all codes,this should reset the ac system circuit.Also check the low side clutch cycle switch,it may be the problem.

The car has been sitting for almost a year. I started it today to drive out of necessity. The A/C clutch does not engage. How do i jumper across the pressure switch to add freon? Thanks, Ken


dont!!! an you start to add freon, itll start to cycle the compresor clutch until within safe operating pressure and then it will hold clutch in constant. charge liquid(with can upside down). if wont take freon in this manner than your more than low on charge. running low on charge will quickly destroy pump, especiallt those old harrisons. the refrigerant also cools the compressor. good luck and wear gloves-
