Electronic Column Lock

Last weekend I was at Lime Rock Park for a vintage car race. I went with my freind that was driving a 1999 automatic coupe (a Canadian car). When leaving, his column locked up on him. Fortunately, I was able to shake it loose and we were on out way.
I told him about the recall and he went to a local dealer on Monday and had them look at it. They ran the VIN and told him the recall (00406) was already done.
My freind insisted that the column locked and that he wanted it looked at. After three days they verified that a new lockplate was installed and that it must be a bad column lock motor (a guess?). The result is that he was charged $350 and is not at all confident that he will not get stranded again.

I have two questions:
1) If the new lockplate is installed, how could it jam?
2) Consider question #1, how could the actualtor motor jam the steering???

C4C5 Specialist...can you comment?...anyone???

Nope, but someday.
HI there,
Comment, hm, basically, the relay would have to be checked and most likely replaced.
If the lock plate had been installed, the column WOULD NOT lock, at all.
It would be suggested to have another dealership look at it and get the regional service representative for Chevrolet involved.
$350, for something that should be covered under GM special policy 05081, is just plain wrong.
Allthebest, c4c5:hb
