mwhite308 Regular Date registered: Aug 2015 Location: Birmingham, Alabama Vehicle(s): Landrover LR3, 1984 Ferrari 308, 2003 MercedesG500 Posts: 65 | replaced compressor but it wont turn on I replaced the compressor on my 2003 g500. The old one would engage but the new one will not. Hard wire tested and the compressor works. Do I have to do something with the star system to make it engage again? Kind of like the TC module? | ||

There is a pressure switch in the system that will prevent the compressor from engaging if the pressure is too low or too high. | ||

The only way that has ever worked for mew is to pull a hard vacuum for 30 minutes or so to clean out the old R-134a and any moisture. Then add exactly the amount of R-134a that is shown on the label. On my 2000 G500, that is 2.277 lbs. If you lost any oil in the process, I would guestimate how much was lost; and add it back with the refrigerant. Doing it that way has always worked the best for me when servicing my A/C. | ||
