How do I get fire to an AC compressor I just replaced on an 2001 Chevy Z-71 5.3?

Did you fill the system with refrigerant? That system should take 1.8 pounds. Next place to check is the low pressure cycling switch. It's the switch on the accumulator (big round silver thing on the fire wall on the passenger side).

Good luck.

Ac compressor doesn't turn on

Have you tried putting a wire jumper (paper clip works) in the compressor cycling switch in the low side of the system?

The A/C on my wifes 97 Blazer is not working. I

do u have power to the AC compressor clutch cycling switch, this switch is in the low side,either in the larger of the two AC lines or in theround canister called the "Accumulator" under the hood, still think u have lost your charge,this year is prone to AC compressor front shaft seal leaks. below is a picture of the clutch cycling switch.

The ac compressor clutch does stay on

Hello narto7
If you replaced the compressor yourself and tried to charge the system with those booster cans from the parts store, then air and moisture remained in the system. This will prevent you from getting the correct
charge and the correct pressure in the system. This can cause the lowpressure cutoff (on the accumulator right side of firewall) or depending on how much R134 was put in) the high pressure cutoff (on the compressor) to cut power to the compressor clutch assy. If this is
the case, have the system evacuated and charged with the proper
equipment and that should clear it up. However if it was charged properly, check the 2 cutoff switch's I mentioned. There should be power in and power out on both with the a/c on. There is also a relay
for the a/c you can check. But due to the split year in 95 it's located in
1 of 2 places, in the fuse relay block under the hood or under the right
side of the dash above the glove box. Remove the box for easier access. Hope this helps

I just had to have the A/C compressor replaced and now the engine seems to surge at hiway speeds. More so when cruise control is engaged. Is there any connection to the replacement and the engine problem?...

There is no points on this model,but if you are running the ac on low fan speed,it will cycle on,and off to keep it from freezing up,or the ac has a restriction in the orifice tube,and is making the ac compressor cycle on,and off,or there is not enough freon in the system,and this also,will cause the compressor to cycle on,and off,try freon maybe.If this was helpful,please rate,thank you.

The AC compressor clutch repeatedly tries to kick in when the AC is off (vent or defrost is on) in my 2006 Ford Ranger. What to do?

The ac compressor will cycle when in the defrost position. The system is designed this way, so that the freon will circulate at times in the system so the seals don't get hard or crack. Otherwise, you would have to replace the seals in your ac about once a year. If it is cycling too often then the freon may be liw and the system needs recharged. If your ac does not work and you are not going to repair the system. You can unplug the compressor so it won't come on and put a load on the engine.

1995 f150 supercab v8 ac not working and the compressor clicks on every few seconds. What should I try?

If it only cycles on and off then it is most likely low on freon. The pressure on both service ports need to be checked to be sure that this is the problem. the pressures should be 50 to 70 psi on the low side and about 225 to 275 psi on the high side.

A/C Compressor not kicking on

The power to run the compressor clutch coil goes from the battery, to the AC Clutch Relay, somewere in the engine compartment fuse box, then it goes to the positive side of the AC compressor clutch coil; goes thru the coil, activating the compressor, and then goes to complete the circuit through another switch (high pressure protection switch) in the back of the AC compressor and finally reaching negative or Ground.

Disconnect the AC compressor clutch connector and using a 12 V bulb with 2 wires (test lamp) check the following:

1.- connect 1 lamp wire to battery neg; with the other check both pins at connector with the AC in the RUN (AC and ignition switch on ) you should have power in one side.

2.- connect 1 lamp wire to battery positive and with the other check both pins at connector, lamp should light getting the ground from the clutch connector thru the high pressure compressor switch to ground.

On the other side what makes the relay close and let the power flow to the clutch works with the low pressure switch, (if the freon pressure is too low it opens and kills the ground to the relay coil and that kills the compressor), that low pressure switch is in the low pressure side of the freon tubing, the fat pipe that comes from inside the firewall into the accumulator/dryer, a big aluminum cylinder sitting on the right side of the engine compartment in GM cars.

To know if the low press switch is the cause you can unplug it and connect both legs with a paper clip for a minute or two, no more, you don't want to damage the compressor. anyway if jumping the switch makes the compressor come alive and kick in, you either have low freon pressure or a bad switch; it's time for the pressure gauges and check how the compressor is pumping and that is better left to a pro.

By the way you said that your system is a R-12 system, have you considered switching to R-134a the new "ozone friendly" freon? to do that you need to evacuate the system with a recycling machine and pull vacuum in your AC, if it holds the vacuum for a while, then you can be sure that there are not leaks and then dump 1.5 or 2 pound (check the labels in the engine compartment) of R-134a into your system. it will be a good idea to put some fluorescent leak detecting dye in the system to check for leaks, just in case..
