I am brand new to this forum and I'm hoping someone can help.

I have a 2001 Olds Silhouette and my rear A/C vents will not blow out any air. The front unit works fine so I know it's not my compressor.

It was working perfectly prior to an accident in January in which I had to have the driver's-side sliding door replaced. I have taken it to the same body shop 3 times since, each time a new issue with the same door. (They were responsible for each problem incurred).

This past weekend I tried to use the rear A/C for the first time since the accident, and now all I get is the sound of the fan coming on, but no air. I am wondering if the connection to the compressor may be in the door, and it possibly was not hooked back up.

Does anyone have any suggestions or ideas?
