a/c not working, but no a/c codes

I took a look at a 2010 that has been wrecked on the front. It got a new used radiator support, condensor, radiator, etc. He said it worked for about 5 months and has quit working. He put a used compressor on it and charged it up. No luck. Then he changed the amplifier. Still no luck. When I put the laptop on it with techstream, it had no a/c codes. It did have some airbag codes due to him not replacing the airbag when he fixed the car up.

Going to the live data, I saw the target compressor speed was 0. I went to active test to try to turn the compressor on with no luck. While in active test, I was completely locked out of all fan and a/c related buttons. I couldn't turn anything up, down, or off with the controls. Once I canceled the active test, everything worked normally. I tried clearing codes and refreshing health check 3 different times but all the results were the same. No a/c codes. All lights on the buttons turned off and on normally unless I was in active test.

Any ideas?

 

He said he pulled a vacuum and it held, so I didn't put the gauges on it.
