If someone has time and has a 02 or 03 F150 FX4 with a radio-cd player ..the OEM one. With the radio off and the key out of the ignition, turn the ignition switch to Acc. and see if a fan runs behind the radio-CD player. After that turn the Acc off and take the key out. Turn the headlights on and see if that fan runs...Thanks a bunch guys.

 

Yup, with oem cd/radio off
Turn ign to acc and cd fan/motor runs
Turn key off and turn on headlights and cd fan/motor runs
edit 2002 screw fx4
