Just looked at your profile and I notice your from Aruba, South America and your Vec is badged as a Chevrolet. In that case I could be wrong then as I'm sure the US didn't get the YH, in which case sorry for confusing things. Re your "check safeguard" in your other thread, you don't drive an Estate do you, you might know it as a Sport Waggon?
EDIT:- Just thought, the Brazilian "Vectra" is our Astra,but the Mexican Vectra is the same as ours. notsure.gif Does your car look like mine? If it doesn't then my Estate question might not come into play in that case. On our Vectra Estates there is a little glass breakage wire that runs around the glass, it can get damaged and the Check safeguard comes on, its quite common. I have also had the safeguard sign come on when I have disturbed the wires around the ultra sonic sensors in the roof, a quick clean on the contacts solved the problem.
