1997 s320
1997 s320 AC issues.

Sold my air-conditioning unit worked fine until the compressor seized up on me. I replace the air compressor in the dryer and then I had to replace the battery on the car. When I replace the battery all of a sudden my AC unit would only blow through the defroster and will not blow cold after getting a recharge To changing the battery have caused issues with in the control unit? I've been to 1000 forums and I cannot figure out how to get in or read the error codes on this particular control module. I do not hear any vacuuming hissing sound so I'm praying that's not the problem. Help!
