Blow into the hose connected to the wastegate and see if the armature moves to open the gate; alternatively, you should be able to open the gate with light hand pressure. Wastegates fail when either the armature freezes or the diaphragm perforates. Over twenty years, that unit has been thoroughly cooked.
I used to see gate failures at 150K miles on my Peugeot 505 turbos, which had a similar Garrett turbo.
