What year is your Dodge ram? i have a 1997 4x4, 318, and it has two vacuum check valves going to the heater controls. the first check valve is on the right side of the intake maifold, just below the hose going to the pcv valve on the right side valve cover. if you follow that hose to the right side of the firewall, there is a tee in the vacuum lines, if you follow the line that goes into the cab, that line has another check valve. i found that the one at the intake manifold was the valve that failed on me. good luck

Are clack valves used in cars?
If you define a clack valve as an automatic valve that allows flow in one direction but prevents it in the opposite direction, then yes, in lots of places (see the related question). For starters how about: * check valves in A/C compressor * check valves in diaphragm-type fuel pump * carburetor accelerator pump valves * vacuum retention valve on brake booster * check valve in brake master cylinder * usually several in the automatic transmission valve body * exhaust flapper on diesel truck (ok, that one's a stretch) * and probably others....
What causes the air conditioner to blow on the windshield and through the floor vents on a 2000 Chevy Astro Van?
This sounds like a vacuum line problem. First thing I would check would be the vacuum lines and check valves contained in line with them, as well as the vacuum canister. Could also be a problem under the dash with the vacuum actuators in the HVAC unit. Another slight possibility also could be that the controller isn't functioning properly. Hope this helps. Good Luck!

First check for vacuum leaks in the hoses, especially the hose going to the vacuum modulator on the distributor. Then check for a bad vacuum modulator. Other problems may be worn or bad valves, piston rings, or timing chain or timing gear wear.
