Took my '95 ETS to Lund Cadillac to have the AC recharged this January. Had to wait over 2 hours to get an estimate that came back at over $2k because of a leak that would require major replacement costs. As I'm a snowbird I didn't want to spend 1/2 the value of the vehicle on the A/C so I left without the service being completed.
Fast forward to Nov - I'm back in town, take the ETS to a small service shop and get the A/C recharged for $205, leak was in the service port(think tire valve stem).
Boo-hisss Lund service dept. for trying to do major surgery where a simple fix was all that was needed!
