Both used but were working fine when removed. I bought the AC compressor used from a used parts store...When I took it in to have the AC reworked the mechanic said I didn't need the compressor.....I bought the TCCM used and put it in thinking it would fix my Tahoe 4x4 engaging issue but no luck...So I put the old one back in and on to the next issue to try and figure this 4x4 issue out....

If your interested in these parts shoot me an email or response on this thread...

Thank you.

( These parts fit my 99 Tahoe 5.3L V8 engine, automatic trans..)
