Question about 2005 Chevrolet Colorado
So I think I have a bad bcm or maybe its the multifunction switch but im leaning towards the first. I drive a 2005 chevy colorado standard shift. The blinkers work sometimes as with the hazards. the hazards always work if the engine is off... the electric ports seem to work sometimes but always when the engine is off. the lights behind the air conditioning controls light up dimmly when i shut off the engine until i open the door some amount of time. (but not at all when engine is running) the highbeams work when the engine is off or when the lever is pulled towards me. interestingly this also makes the blinkers work. the automatic headlights stopped working when i discovered this. i can also make the blinkers work by turning the lamp nob all the way to the left but this turns of my low beams. and no matter wich way i flick the lever after doing this it blinks left until i turn on the parking lights or low beams. also sometimes when i flick the lever so that the right blinker should come on the left one does instead. also (seemingly unrelated) im throwing codes for both o2 sensors.
You have bad switch if it were a bcm you would lose all of your lights

YOU MIGHT WANT TO CHECK THE BULBS IN THE REAR LIGHTS THEY OFTEN STOP WORKING IF THERE IS A BURNT ONE . IF NOT THEN CHECK TO SEE IF YOU CAN HEAR THE CLICK WHEN YOU ENGAGE YOUR SIGNAL EACH WAY IT MIGHT BE IN THE STEERING COLOUM WHERE IT CONNECTS TO THE SIGNAL ARM

replace the main headlight switch and the connector to that switch, the connector can be obtained from the dealer only in most cases.

Sounds like a short or the relay is going bad to the headlamps. You may be able to google for the diagram but probably will need to get a repair manual from the nearby auto parts store for appx $25.00. I would start by checking continuity with the battery disconnected on that side from the positive wire to a ground. Also start with checking the relay, they are usually generic and you should be able to swap two as long as the numbers match and see if that fixes the issue.
