Hey everybody! I need some help. I just bought a 06 supercrew 4x4, 46000 miles, well taken care of. The high beams will come on for 5 seconds at the most, sometimes not at all. Low beams work fine. There are no fog lights on the truck, but it has the switch to operate them. When I flip the switch to turn on the high beams, the indicator light for the fog lights illuminates. The high beam indicator ( blue light ) is not on. The flash to pass does not work either.
So far I have swaped relays. I replaced the Multi function switch. I inspected the connectors to the bulbs and the headlight switch. Haven't found anything obvious.
Thanks!
