I love the horizontal sliding windows in the Rover. Now that it’s getting cooler, I’ve tried to “lock” them closed with the little knob thingy but once underway the vibration causes the windows to slide open. There’s probably a way to adjust the knob (or replace them) but I went the broomstick-in-the sliding-glass-door route.
Found these little plastic tubes at Lowe’s and cut them to fit in the groove. The little tape “handles” make it easy to take them out if necessary.
Please note, these are not for security. Just a lo-tec way to keep the windows closed. Sort of. There’s about a 1 inch gap between the two sliding panes in the back but I need that to vent the carbon monoxide. According to google, a diesel engine generates less but not zero.
