Cannot get the car's computer to acknowledge and read the new air conditioner compressor that has been installed.

Hey MERCS600,

A scan tool is needed to access the HVAC and clear the codes. This video will show you how

Do you have pressure in the system? The compressor will not come on without having at least 70 psi of static pressure inside the system.

Here is a guide on how to do it
