Problem with auto headlights
HELP!!!! I installed oem fog lights and a new stalk to activate them the stalk has the auto headlight switch so I purchased a sensor(on the dash) to active them and installed that. So I went down to the dealer where I purchased the jeep and asked them to activate those options in the PCM ($120 later) the fog lights work fine but the teck said he could not find the auto headlights in the PCM to activate them. Any suggestions?
THANKS!
THANKS!

I believe that function is controlled by the Body Control Module (BCM). It controls all that stuff that happens after you turn the key off.
