Technical Climate control not responding

[124spiderman]

Hi after fixing my air bag module after it failed and doing the proxy alignment I now have no air cond. the display lights work but go to turn the compressor on and it turns itself off after a few moments and will flash the air conditioner symbol and also no response from the fan speeds?
Any ideas?

Hi

Check what the OBD thinks the refrigerant pressure is

Check pressure reading with engine off then engine running
