my a/c is working fine but after a while compressor will not engage, hence, no cold air. if i re-start car, a/c will work fine. any advice will be appreciated.

This is the most common A/C problem that Mercedes(single belt drive) has. Now how many hours have been spent trying to figure it out? Start first by making sure the drive belt is tight! The reason that this happens is that MB installed a relay to monitor belt slippage due to the A/C compressor seizure.

thanks MB DOC for your reply. is there a way of tightening up the belt without replacing the belt tensioner. thanks again, cheers!!

When the tensioner breaks it needs to be replaced and can't to my knowledge be repaired. I think we sell it in the partsshop if you need one.
Good luck with the repair.
