It could be a temp sensor problem. You need an ac manifold gauge set to check the pressures. Could be a pressure switch problem or an expansion valve. System could be over or under charged.
You need to read pressures. Also need a high end scan tool to check for codes in the HVAC module. You can use a scan tool to read live temp sensor data as well.
