Luxury Coach Lifestyles - View Single Post - Air Leak From Exhaust Port of The Vaccuum Venturi Assembly

Thanks for your answers. Here is a post script: After trying two new valves which acted the same as the original, i concluded that the valve was manufactured incorrectly. I carefully pried the cover from the valve, cut about 1/2 inch from the spring and reassembled the valve using RTV as sealant. The valve now works correctly. It exhausts air as it is building a vacuum in the reservoir. When the vacuum reaches about 18 in. Hg. the valve shuts off and no more air is exhausted. It will remain in the shut off position until the heater controls are operated. Vacuum is used by the blend door motors and then the valve goes into action and generates vacuum

If anyone is interested in this repair, I am willing to share my information. This is such a great website for us DIY guys.

Thanks again,
Carl Tesch
