I have a 2000 4.3 4wd blazer and the a/c compressor is leaking. I bought a replacment compressor but was wondering if anyone has a link or video that can walk me through the process.. ?

 

Remove the belt, recover the refrigerant, remove the lines from the compressor, disconnect the clutch electrical connector, remove the 4 bolts, disconnect the high pressure cut out switch on the rear of the compressor. Some compressors come with a new high pressure cut out switch, some don't, so you mat need to transfer the old switch to the new compressor. Lube the new O ring with refrigerant oil, before installing the lines. Torque the bolts evenly in an X pattern to 18 foot pounds, then again to 37 foot pounds. If the bolts are not tightened correctly, permanent damage can occur to the new compressor case. Evacuate the system for a minimum of one hour, & re charge. If the system is not evacuated before charging, recharging to factory specs will result in an overcharged system and poor performance.
