Exactly how much refrigerant did you charge into the system when you recharged it? If the suction pressure is varying that much you most likely over charged the system and got a liquid flood back which took out the compressor valves.

Have to mash gas pedal on 2007 buick rendezvous to crank, after starting it will idle fine but sometimes die for no apparent reason, what would cause this?


Test your fuel pressure for leak down while sitting.. It should hold 52-59 psi... If not it could be a weak fuel pump..Also test the fuel pressure regulator to see if its leaking gas into the vacuum lines.. Alot of times you can do this by running the vehicle then leaving it set for 45 min and then removing the vacuum line at the fuel regulator and checking for wetness... If its wet with fuel its leaking and needs replaced..

I have a ch 28 gal (wl611700aj) air compressor,it pumps up to 80 psi.wont pump up any further but does keep running.whats your thoughts?


Here are a couple of things to check. While the compressor is running spray soapy water on all airlines, fittings, bottom of pressure switch, regulator and drain valve to make sure that they are not leaking. A small leak will prevent the unit from reaching cutout limit. Repair as needed. Next unplug compressor and remove cover to expose cylinder and piston. Move piston to top of cylinder and check for scratches or wear neer top of cylinder. If scratched, air is bypassing piston ring and will not reach cutout pressure. If cylinder looks good and no leaks then problem most likely is valve plate/ reed valves or head gasket. Problems within head will cause low pressure and air line to tank will be very hot. Bad reed valves will also cause air to blow out of intake when it reaches 75 to 80 psi. Parts are available at www.chpower.com or at www.toolpartsdirect.com. Good luck

Air not cold enough to cool house


Make sure the outside fan is running. Also check the high side pressure, I assume the 70# is the low side pressure, so you can tell what the compressor is doing. If the fan and compressor are both working, make sure there is good airflow through outdoor coil and check that it is clean. Let me know what you find.

1998 Jetta TDI - AC compressor turns but no cooling


something not right here ,firstly why didnt you just renew the clutch instead of a complete compressor ?? secondly do you have a machine to recharge the system and if so are you using it correctly ,the reason i ask is because in the machine the low and high pressure pipes are interconnected in the body of the machine so yes it would show these pressures.When refilling a car once machine has weighed the gas leaving the bottle shut off the red line and start engine leaving the blue line connected ,run engine at 2000rpm with A/C on full for about 3 mins to draw the gas in from the machine .Then close blue line and and do a recovery to see how much gas was left in the machine.Also did you put compressor oil in when you re fitted the compressor about 100cc is enough ,this is better put in directly into compressor ,then vacumn to about -750mg or a stage one vac pump and omit the oil recovery cycle .When running the air temperature coming out should be about 7.5centigrade is good but some cars will drop to 5C anything below 9C is ok ,and forget to clean out pollen filter

1997 tahoe wont start


it is not the regulator if it has 40 lbs of pressure try to pinch off the return line and if pressure drops quickly it is either the check valve in the pump or the rubber seal between the pump and the sending unit
