I just got the truck and when I got it the right front blinker was not working (it will turn on but not blink) and my right low beam was not working. I got the truck home and replaced the bulbs and when I replaced the blinker it still did not work. When I replaced the bulb on the right side low beam my left side low beam stopped working. All other lights work even high beams and all other blinkers work as should. I am getting power everywhere but the sockets for these bulbs appear to maybe be grounding out but I cannot find where. The bulbs in these sockets are new and work when I put them on a different socket. Any input is appreciated.
have the same problem?

It sounds like you have a wiring problem or the BCM is bad and needs to be replaced but to be sure lets check all fuses for the truck none can be out.
Check out the diagrams (below). Please let us know what happens. If it is the BCM you may need to have it programmed if you cannot find a used one.

I checked all the fuses related to my lighting system and they were good. Should I check all of them even if unrelated to lighting? I hooked the scanner to my truck today at work and it threw a code on the BCM but it was not anything to do with lighting and I cleared the code to see if it returns.

Yes, check all fuses. Also, check the wiring continuity and if everything checks out I would replace the BCM.
