SOURCE: A/C COMPRESSOR DOES NOT COME ON

sounds like your a/c is freezing up. i would recommend checking your charge level (a/c recovery machine) also ispect lines to see if there is a restriction (a/c line has frost on it) the a/c control panel could be defective or even the engine control computer (receiives activate signal from the a/c control panel and activates the compressor) i haven't seen many pressure switches fail on bmw's but if you wanted to jump it to test i would try all possible ways of shorting it out, its a 5 volt signal from the control panel. but it doesn't sound like the switch has failed. my recommendation is to recover the system and pull a vacuum on it for 30 minutes and start your diagnosis with the correct fill level. 1.63 lds of r134a

99 chrysler lhs air compressor won't work


unplug the low pressure switch in the air conditioner line near the dryer with air switched on , jump the connector with a short piece of wire to see if the compressor clutch engages. If it does your pressure switch is bad. If the pressure switch is good then there is a fuse near the compressor somewhere that may be blown. If it blows new fuse your clutch is bad.

A/c compressor won't engage 2005 equinox


most likely the ac compressor will not engage because it needs a freon charge.The simple way to tell if that is why without having special equipment is to find the pressure switch located on the low pressure line and jump the switch with a peice of wire. if the clutch engages when you jump the switch then you need to charge the ac with 134 a freon

Air conditioner not working on 1993 bonnevile, compressor not engaging, charge good, power at low pressure switch, switch is closed, need to know what turns a/c relay for compressor clutch on, clutch...


the ECM supplies the ground circuit for the a/c clutch. the high pressure switch also needs to be closed to engage the clutch. when the low pressure switch and the high pressure switch are closed that completes the power circuit to trigger the relay.then the power on the #30 terminal can connect to the #87 terminal to send power to the a/c clutch.

Compressor will not engage on 2001 Impala? Where is low pressure switch located on 2001 Impala


It is located by the accumulator or dryer , a long canister shaped part, that will

have a pressure switch attached to it, and a two wire molex, if there is freon pressure

in the cannistor, the switch will close and send voltage to engage the clutch on

the compressor, if there is no voltage there the clutch will not work and you may

have a blown fuse or bad switch on your dashboard. i would check for voltage

at the pressure switch 1st, if its there, pull the molex off , jump it out and see if

the clutch engages. if you have power and you jump out the molex and the

clutch does not engage, you could have a bad clutch or bad compressor.

if it does engage, just replace the pressure switch, if you do replace it, make

sure to lube the seal with pag oil. good luck!

A/c compressor engages intermittently


Check the connections on the plug going to the compressor clutch and on the pressure switch on the low side. Also check the gap on the clutch. It may be too wide after where to engage correctly. Good luck.

Sounds like you may need a compressor ? Start the vehicle and verify the compressor is not engaged , if it is not take a small hammer and lightly tap on front of the compressor ,it should engage.

I need to know how to jump the ac low pressure to get my ac compressor to come on.


If you look on the low pressure side of the AC system you will see a plug that is incorporated in to the line. It will have two wires leading to it. Remove the plastic clip that attaches the two wires to the sensor and use a short piece of wire to connect the two terminals in side the plug by putting the ends into the cap. This will bypass the low pressure sensor and allow the AC clutch to engage and begin to cycle again. Remember this low pressure switch is there for a reason. If you don't add more r-134 to the system and allow the AC compressor to cycle you will destroy the compressor. You need to charge the system when you bypass the low pressure switch and get the system up to full charge status and reconnect the switch.

Ac clutch will not engage 1998 gmc sierra


sounds like low or no refridgerent in the system. start there. You can the cycle switch (low pressure switch on the side of the reciever dryer. the alumunium can on the left side of the engine in the back. You can also jump the two pins with a jumper wire and see if the compressure turns on then. Do not let it run for more than a min. you could burn up your compressor.

Good luck
