Spent ~week fabricating fridge and secondary battery support for hitch basket, etc for wife's 2022 Sequoia (ole good V8). Loaded it up for the family camping trip. Made maybe 15 minutes, one of the kids farted, cracked down the hatch window and could not bring it up. The glass moves down, but not up.
Returned back, took the hatch door apart, could not diagnose the problem in an ~hour. Spent another two hours moving everything into my trusty 2019 Tundra. Driving 3 kids 500+ miles on the rear bench of DC truck is a nightmare.
Got back home yesterday, used my lab power supply to drive the glass up (motor works), so that the wifie could use her Sequoia while I'm out in the woods, healing family camping mental trauma. Took the switch out and apart, only to find it is a dumb mechanical device with couple of resistors and LED. Switch is good, motor is good, then it must be either a wiring harness or ECU mounted on the hatch, right?
Found the diagnostics step-by-step in the Volume 7 of 35 lbs of 2011 Sequoia repair manual. Highlighted the problem I found. I still have a week of PTO left, so facepalm imprints still have some time to heal...
