On Golf/Jetta and new Beetles, current to the A/C Compressor Clutch -N25- is supplied by the Coolant Fan Control Module -J293-. This module is
switched by the A/C switch -E35- on the manual A/C systems. On Passat models, the current to the A/C compressor clutch is supplied by the A/C
Control Module -J314-. Inputs from pressure switches, temperature sensors and other control modules are processed by Coolant Fan Control Module
-J293- to determine the compressor on/off state.
