On my way into the car wash, however, was not a good time to discover this.
Fortunately, I managed to jump out of the car, find the call box, and get the wash shut down before serious amounts of water were fired into the car, but it was a rather nerve-wracking few seconds there.
It seems to be intermittent; soul_diaspora tried a few times later in the day, and eventually it worked, so it's closed now, and we've put a piece of tape on the switch to remind us to keep it that way until we get it fixed.
The folks at the car wash1 were kind enough to give me a voucher for another car wash once the window was fixed.
1: The Pioneer station on Industrial Ave., if you're interested; I've been happy with their soft cloth wash since they built it.
