I'm getting a Ventilation Override Module Com Failure on one of my Intellipaks. Can't seem to find any problems with the communications cable to the VCM that tech support believes the problem lies. Anyone have any ideas what else could cause this? Never ran in to it before and have 13 of the same UCM controls. 1996 Vintage. Thank You.
