I’ll try that trick but I was able to actuate the valves with my hand. I’m thinking it’s the pump. I followed the vacuum lines and I don’t see any cracks or loose connections. I lose sight of the line when it disappears behind the bumper area.
Yeah I was able to actuate mine as well, but it took some force. Try lubing it and let me know how it works out!
