Default AC compressor problems, advice?

there has been a strange noise coming from my engine on my 2002 Dodge Dakota v6 3.9L. i determined it to be the AC compressor, and took it to my auto repair guy, who told me the drag it was creating was very bad for the engine. at that time, the compressor still worked, and i could use the AC with no problem. the noise went away if i engaged the AC, as the clutch would disengage.

so we had him bypass the AC with a new serpentine belt.

now that it is getting to be high 70s to mid 80s everyday, i would really like to have my AC back.

i spent $80 at junkyards yesterday getting a new bedliner and new bumper (both in great shape) and now i think it is time to work on my AC. so, since the compressor works, could i just replace the clutch on the AC unit? i have had several offers for used, full assemblies (compresso+clutch) from crashed trucks, or from junkyards on ebay.

as it looks to me, my options are:
1. purchase a brand new AC compressor+clutch assembly for $250
2. purchase a used compressor+clutch assembly from junkyard for $70
3. use my current compresser+NEW clutch assembly kit for $78.75

any help, or more suggestions to help me save some cash is much appreciated. sorry for the long post.

If your AC works, install a new clutch.

If you replace the compressor you will also be paying to recharge the system. Also you know that your compressor is working, if you get a used one, you do not know for sure that is is OK.

Mr car guy is right. If the compressor doeas work, no need to replace it, just fix the clutch...

I found a rebuilt compressor/clutch assembly on ebay for $86.35 plus shipping of $15.88. I have bought from this seller without any issues.http://cgi.ebay.com/ebaymotors/Rebui...#ht_2523wt_732

For an extra $13 including shipping I'd buy the rebuilt compressor/clutch unit, pull the clutch off and save the compressor in case I ever needed it or resell it.

From my experience if the clutch is bad so is the compressor that's why the clutch failed. Usually either through higher strain on the compressor or from a front seal leak washing the bearings.
