Has anyone had problems with their Autometer guages fogging up? My trans temp and EGT guage fog up behind the display glass, especially this past winter. The boost guage isn't such a problem, I'm sure due to the intake air flowing to it, but the pointer will stick periodically on it. A light tap on the pod and it comes back to life. The trans and EGT guage is getting to be a bigger problem as time goes by, as the the glass is being stained from the buildup. Anyone out there with the same problem? If so, did Autometer replace them or can they be serviced? Thanks.
