Low beam headlight issue

[DwnSthCummins]

06 3500 Cummins 4x4

low beam headlights are not coming on. High beams work, fog lights work. No power coming to the connector for the low beams. I’ve checked all of the simple things, switch, fuses, grounds, bulbs, etc.

Need some help from ya, it’s driving me nuts!

thanks!

Trace the wires back to the TIPM looking for rodent damage?

Test the in-cab switch with a meter? Wait, you listed that as something you'd checked.

Lift the TIPM out of it's holder and check for corrosion at the connectors?

Mine was the FCM on the tipm. I got one at the junkyard for $35
