The blend door motors are not going to cause no power to the compressor.
So, we need to find out if the compressor is able to function by jumping 12 volts to it. You can do this by removing the relay and jump pins 4 to 2 and the compressor should come one with the engine running.

If it does, then we have to find out why the relay is not being commanded on.
We do this by checking power at pin 1 and 4 which should be 12 volts.
Then we need to check pin 3 for ground when the compressor is turned on.

If this all checks out, then we need to check the pressure in the system because it may be under charged causing the pressure switch to prevent the compressor from coming on.

Please run through this and let me know what you find. Thanks
