I installed a new AC compressor in a 97 Buick LaSabre. How do I charge the system without taking it to a service station. Is there a way to get the compressor to kick on from the control panel.
Yes there is a way to kick on the a/c compressor.In my honest opinion you should get the system pulled down with a vacum to remove any moisture from the system before adding refrigerant.Doing the keeps the system running good and if you don't it may void your warrenty on the compressor.To get the compressor running to ad refrigerant locate the low pressure switch in one of the a/c tubes (It should be a two wire pigtail)now unplug it and jump it with a paper clip or jumper wire.With the car running you should hear and see the compressor kick on.Please be carfull there is nothing in the way of moving parts before you begin.
I believe your system takes 134a refrigerant which you can get at most auto supply stores. However you replaced a major part so you will have to account for the lubricating oil which also circulate in the system. If you take it to a shop, have them include an ultra-violet tracable dye so any leaks can be detected.
The comprssor requires refrigerant to run from the control panel.
I'm looking for the answer to this one too. THERE IS NO JUMPER. It's some sort of differential amplifier has 3 pins and it must be the best kept secret since no one seems to know this one.

Cannot locate the low pressure switch. Someone told me it has to be done with a computer or there was a combination of buttons on the control panel you can press to get the compressor to kick on to add the refrigerant.
