    I have a 2021 Toyota Tundra Limited. I’m having a reoccurring issue where I must re-initialize the auto up/down position of the passenger window to get the driver side window switch to control the passenger window. After the truck sits over night the passenger window seems to lose its position, and I must go through the whole re-initialize routine. It’s sounds like the window doesn’t have a constant 12-volt power to store the position memory overnight. If checked all the fuses and they are all fine. Anybody know which wire in the wiring harness going to the window motor is the constant hot?
