If you recall from a previous post, my repair shop originally thought that the knocking was my water pump goiong bad. While the pump did need to be replaced because it was beginnning to leak, it turns out that was not it. It was actually the AC compressor. Not a cheap repair.
My question is...How frequently should the compressor cycle on and off. It seems like it cycle very frequently. Once it cycles off, it cycles back on within a matter a 4-5 seconds. Also, I can really tell an audible difference in the engine when it cycles on. I know that on most cars you can tell with AC compressor turns on but it seems like it should be more subtle. Anybody have any thoughts? is there a setting somewhere that controls the compressor?
