There's a Window Lock button on the driver's door console, you may have bumped it with your elbow.

Was this running normally and just started this, or has it been sitting for a while? How many miles on it?

Did you check the security system?

That is what mine do when the system is tripped. Also, you might swap the associate relay with the A/C or whatever relay is the same as the auto shut down relay in the Power dist. center under the hood.

Just spitballin'...
