Now Im confused..97 Lumi 3.1 A/C probs...

Well I replaced the Compressor several wks back and then tried to charge it...NO DICE... then I replaced the tube Filter still wont take a charge.. guage shows real hi Pressure 100 psi+ and in the red so I start looking around... the pulley is spinning but the clutch is not... Advice on how to ck this is always appreciated considering Im tired of Forkin out 75-80/hr... :banghead:........ I really could use your advice Richtazz.... Youve been a great help in alot of posts... along with all the other regulars on the forums


Thnx in Advance,

Myx

You can try getting an initial chrg in by holding the can upside down to get the compressor started, the right way is to pull the system down, then the first can will go right in. Don't forget an oil charge as prescribed. All this assumes everything you have done is correct and your present procedure is correct.

Tried that already maxwedge... the second I try putting any refrig onboard upright or upside down the pressure shoots WAY UP...100+ psi... its like there is no power getting to the compressor clutch... thats what I want to know,... how to test the compressor to be sure its even working... and Im going out right now in (93 degree heat LMAO) to ck the relays and wiring... atleast no wrenching so to speak... hoping its the compressor relay but I doubt it.... and lastly am I correct... there has to be some refrig. on board to get the clutch spinning or should it come on when I set the controls to ANY A/C setting??? .... For the sake of Mankind any clues would be Greatly Appreciated... I should be able to do this myself... Damn shops will hose me for sure....... Again thnx In Advance to all that reply!!!!

Could the sensor in the A/C line be bad? The sensor that tells all the systems you have refrigerant and pressure so the compressor and the fan will engage.

Unless there are bad fuses or sensors the compressor would engage if there was sufficient freon, you could check for 12v at compressor if ok ground the opposite side this will force the compressor to run even with low freon, the right way to do this is have a charging station hooked up evacuate the system, check to see if it holds vacuum and put an intial charge in it and check pressure as the compressor engages. The "hosing" is your view of a properly serviced a/c system, which is an industry standard, a/c is not a dyer type repair.

If the low side pressure is too high, then it's possible the evaporator core is plugged.
