Q:
I've installed this ac compressor per warranty and specs in my 2003 Trailblazer.
Maybe the old compressor was the same way and I didn't notice (compressor was fine, pulley went bad), but it's definitely the compressor--I hear a faint, but noticable humming coming from it that varies with RPM's, only with AC running...AC performance is rock solid and pressures are in range.
Is this normal?

When replacing a A/C compressor, You always have change all the Filter Items such as Accumulator/Drier, Orifice Tube, and in some cases the evaporator valve. Also flush the system,Air out with compressed air. The Following items mention, "cannot be" flushed. So, with that said, The condenser coil, and evaporator coil "can be" flushed. So, when you do your job, remove the: Compressor,Accumulator/ Drier,Disconnect Hoses From Condenser and Evaporator coils!! After you flush theses Item, begin to replace your Compressor, Accumulator/Drier, and Orifice Tube or Evaporator Valve to torque specs. The Next Step to Vac down the System to 29.7 CFM for at less 2 hrs on average. Now,the tricky part,You need A/C gauges to read High & Low reading.Their is Also a hose to fill the system with R-134a. You should have hook them up before you vacuum the system.Now study Dag Oil and your system.Do it right. If you did it right, the compressor will drink the Freon! 3 to 4 cans.Good Luck!!!Answered on 8/22/2011 by KH from Orlando Florida
