Found this in the driveway, may be off our 2010 Chev Equinox.... Approx. 7" long, plastic pipe with rubber 90* boot. Had a dead bug in it. Suspect some kind of vent....
Just a stab in the dark BJ. I had a 94 Fleetwood it had a similar pipe. It was a drain that went in the bottom of the heater box. The pipe was needed to drain the box because if there was not one there, the wind pressure would not allow the water to run out. It was a big problem on the Fleetwood, Impala SS and Roadmaster..
