    it's ok to do that, but use a fill line that has a gauge on it so you don't overfill it. Stay in the "Good" zone. Or you could slug compressor. The clutch should cycle about 4 to 7 times/minute at 75 degrees f

The problem is that you have air in the system, reon leaked out so there is a leak somewhere,you need to evacuate the system using a sreial vacuum pump, suggest you find a certified A/C technician to check and recharege the system

AC trouble will not take freon.


Have you used gauges on both high and low? Perhaps system is full but you have a bad high or low pressure switch.

My compresor dont want to kikin


Which compressor are you talking about? The air ride or the A/C?

For the air ride, it has fuses and relays. All the door jam switches and cargo doors must be shut.

For the A/C, you would verify that the system has Freon before attempting to replace a compressor. A low pressure switch would deactivate the compressor clutch. The system would need to be Evacuated with a Vacuum pump and then recharged, It is not like changing a starter. After prepping the system, you may need to jump the low pressure switch to get an initial charge of Freon, then reconnect the low pressure harness to the cut-out switch.

You need some type of guage to measure the charge. When the system has enough Freon to let the Low pressure switch provide power to the compressor clutch; the signal will be restored to the compressor.

A/c compressor clutch will not engage


In this case, I would suggest that the low freon pressure switch has activated and prevents the compressor from running and damaging your system in your 15 year old vehicle. To prove this, find the switch and short the switch out and see if the compressor kicks on.

How do you fix this? Get the system recharged. Also have the mechanic check for leaks. The freon escapes somehow ...

Thanks for your question today.

You may have freon in system but compressor won't engage unless it's full under pressure. By jumping the the relay you're doing damage to compressor by running on low pressure. Have system evacuated and recharged to proper amount of freon - usually 4 lbs of freon

in order to recharge the ac you first must clear the trouble code for the ac off warning. when you get this warning the computer shuts down the compressor to keep it from running without the lubricant that is in the freon. clear the trouble code and the compressor will run and you can recharge the ac.

Need to jump compressor on to recharge refrigerant


You should not have to jump compressor to recharge a/c system, when adding freon low pressure switch will kick compr on, if it's not kicking on or it read low freon on your dash, replace both low pressure switch's, both sit along fire wall from left to right on a thin a/c line, when replacing these switch's make sure what ever freon in system is recover.

1997 GMC Savans 35500, Rear Air only warm air


well what I see you have two problems with you A/C ..1- if the compressor is cycling very fast , the system is probably low in freon , this ban takes like 4lb of freon, now, 2-if we have the right amount of freon and the rear A/C don't work and all the vents are working fine back there for sure the problem is the expansion valve located close to the rear evaporator , that valve get stock open allowing to much refridgerant get in to the evaporator and no cooling at all ,in the back,... you can also have a bad low pressure switch located on the accumulator, making the compressor cycling very fast ..the first you have to do is check the pressures if they are OK , change the low pressure switch..then go to the second problem

Air is blowing warm, compressor is not switching on when AC is turned on, I wondering if the compressor is broken or is it not switching on and off because it has no freon?


check the freon level first you need to have a shop recharge it if that dont work the check for 12 volts at the low pressure switch if you have power there then jump the wires and see if the a/c runs if it dose get a new switch

AC air is only cool, how do you recharge the compressor?


You can buy a can or,refil kit of R-134-A at walmart however only put the freon in on the low side (read the directions) if the freon gas will not go in; run an 18 gauge wire from the battery to the compressor clutch switch to run the compressor if the freon gas still won't go in it must be evacuated and, recharged by a shop. only put in enough freon to get the system cold any more than that and, you will lose cooling again (over charge)
