Hello, Hoping for the reset procedure. Buick service had to replace the battery a few months ago. Tried to open the sunroof this weekend and there was no response from either switch. Looked in the manual and it says it needs to be reset after power failure in order to function. Found a thread on a Buick group that suggested holding the switch halfway down, 1st position for 15 seconds. Did this. Sunroof opened to vent position. Now what? It won't open any further, won't close. Can't get to service for a few days.
