I'm sure that this has been discussed before and I did a search on this forum and read many of the posts - but there is always hope that someone has been through a similar situation and has the exact answer.
I have a 98 Classic with a Sanden compressor. I turned on the AC the other day for the first time since last summer. It blew just warm air. I have noticed that for quite some time there is a whirring noise which is preceded by a good click/snap. This can be heard in the cabin while at idle. The whirring cycles for 3-4 secs, clicks/snaps and is gone for off about the same. Today I popped the hood and the noise is coming from the compressor. I started the vehicle and heard this noise. Then I went for a drive and the AC almost seemed to be working - not really cold but not warm either. The air does have that "refrigerated" smell to it. I turned the vehicle off for about 20 minutes. On restart the sound was gone and the AC blew very warm air. Suggestions? Does this sound like classic low coolant symptoms? If so, does it hurt the compressor running it with low coolant?
On another matter the vehicle was showing a Check Engine code for a few days but before I got around to having it read, it went away. Do codes just go away or do they only disappear when the problem goes away as well? I am thinking it was just a gas cap issue (not tight enough) and that it clear itself out after a number of restarts.
Any help or suggestions would be greatly appreciated.
