2002 Sequoia multiplex control module/BCM

We’ve been having trouble with the drivers side power windows and locks on the 2002 sequoia. The window quit operating last week and the drivers side door won’t lock at all. It locks/unlocks when the button is presses. In researching it seems the most likely culprit is a bad BCM. I found one on eBay for $40 but no where have I seen any how to’s on replacing it. I suspect it’s not trivial.

The only reference I found was on a toyota forum where a guy (girl?) replaced it and had to remove basically the entire drivers side dash and it took about 4 hours. Is this right? Or can anyone tell me where this is located on the truck?

We’re going to purchase a new vehicle this month and sell this but if I can fix it, there’s a big difference in price.
