Dieselfixer Posted October 6, 2018 Share Posted October 6, 2018 (edited) Hey All I am trying to find the location of the switch that would turn the engine fan on when the A/C is on. The A/C cools pretty good as long as the truck is moving but not while stopped. I thing the engine fan should come on with the A/C? The fan comes on and off while driving. It's a E7 427 engine in the truck. Thanks!

tjc transport Posted October 6, 2018 Share Posted October 6, 2018 should be a two wire plug on top of the compressor with a connector in it. if the plug is empty run a jumper in it. the fan should the come on. i had two trucks delivered without the connector in the plug, had to go back to the dealer to have it connected.
