The ac compressor clutch isn't engaging so I went to a local scrapyard to find a new clutch and ended up getting talked into buying an ac compressor off a 2007 1500 hd will this work if I put it in my truck. I was told they have the same engine.
If the mounts and drives are the same it should work, but you will have to discharge your system, remove your compressor, drain the replacement compressor oil and refill it to specs and install it then evacuate the system to remove any moisture that my have gotten in, manually turn the compressor to distribute the oil, recharge the system and hope they didn't sell you a bad compressor. You need to find the actual problem first. it could be that the system just needs serviced, it could be a cycling switch bad, it could be a bad clutch/coil assembly. Hope I gave you some ideas .
yes they fit on many years.
