2001 Tahoe Window master switch lost auto down

[Spaul]

2001 Tahoe Master window switch. Everything on the switch works but the auto down feature. It used to work but stopped working. Functions up and down fine but no auto down or express down.

Welcome to the forum from Virginia. Sounds like a bad switch. Grab a new one. If that doesn’t solve it you can always return it.
