Re: I have 12 hours for input :-(
Yes, a Chev. Van might have both a ABS ss and Vss. I did a google search and appears to be a not frequent failure but one that a typical failure mode is 2x on the speedometer.
Yes I did plot out Chev dealers along our route in the Canadian section. Bad thing is our cell phones do not work in Canada.
Almost 8am Sunday morning now. Will disconnect battery for awhile and look under van for loss connections (that would be nice fix.....).
disconnected bat for 20+ minutes. Found VSS, disconnected and reconnected it. Contacts were very clean, no corrosion. Did not find ABS ss.
Hopefully you will hear nothing from me for a week
