Hello All,
I recently purchased a 2012 Tahoe LT package. I'm noticing some of the exterior/interior switches and lights behaving oddly. 1st it was the power folding mirrors won't fold in it out, not even a click or buzzing sound like they are trying.
Then it was a TPMS sensor didn't want to be programmed.
And then the passenger side low beam was out. So I replaced the Sensor(TPMS) that's golden now. I put a set of low beam bulbs in. I tested low to high and back several times. However when I checked for the flash to pass, the lights all went out, instead of the lows staying on and the bright coming on momentarily while the multifunction switch was pulled back, and when I let go of the stalk, the passenger side low beam went off and hasn't come back on since. I'm thinking multifunction switch. I've also noticed the side view mirrors don't return to where I have them set after I shift into drive and get a block away from the house. I have to moved them myself not manually, but with the adjustment switch in the driver's door panel. The headlight control switch has been set to off, auto, and on. The first time I had both low and high beams working before hitting the flash to pass stalk, the switch was set to Auto. After this i went through the reset process for the auto dimming feature, praying that would reset the passenger side low beam(nope). Hopefully I've given enough details of switch orientation, and what happened when I took an action, that someone here might have run into a similar issue. Thanks in advance for any help given. Other than those issues it's a diamond, no stains in the carpet, leather seats are like brand new, and I do mean brand new, 3k miles under 200k and that lil LS motor is healthy, performance exhaust and the DOD has been physically deleted.

Check the right side headlamp fuse?
Might not solve the weird behavior, but hopefully will get your passenger low beam working..

How old is your battery? Batteries can cause gremlins in several areas and still crank your ride.
