Ac will not cool air when stationary. Found coolant fan control module is defective and will not run the fans at high speed. To the point the overheat warning light came on. Basically the complete engine cooling fan assembly was replaced by a used unit from a scrap yard because buying the fan control module is expensive and requires to splice the wires. So I decided to look for a good condition used assembly and just a straightforward replacement to keep the wires intact without any splice connection. This fixed the ac and engine cooling. BTW diagnosis reviled that the fan control module as malfunctioned and the condenser pressure sensor fault.
