Unfortunately I have found this to be an issue in dic electronic it's self, the way to fix that I know of is to replace it. I have the same issue in my 98 transport I have taken it apart and can't find any bad contacts in the unit.

I must say it is a curious problem, we recently got a used 2001 and have just had the same problem. The way it was heating up I felt it was the thermostat so changed that but didnt help. It appears that air pockets are causeing the over heating. On the thermostat houseing is a bleeder vaule which you can use to get the air out. It takes a little time to get all the air out but once I bleed the system out it seems to be fine now. Hope this helps
