Hey Scotty, I have an LS400, year 2000, with 254,xxx miles on it, with no check engine light, and I have an issue with the windows where I can roll the windows down by holding the unlock side from the outside with the key and to roll them back up hold the lock side and every window will roll up or down when I want. But when I’m inside the car, not a single switch from the inside will roll them up or down, the doors lock and unlock every door from both the passenger and drivers side but the windows won’t work from the inside and I’ve already bought two master switches hoping the first one I ordered was a dud, I’ve also checked and replaced any relay and fuse to do with the windows, the previous owner didn’t tell me and I completely missed it, thanks for your time!
