The part number on the one I purchased is: 1-05174703AA. If I remember correctly, it was about $25.00. Before I bought it, I noticed the same problem that you did; replaced the bulb and still no light. I cut a small strip of aluminum and bent a tab on the end to make the contact that on the the original had broken off. I then fit it into the slot over top the original, reinserted the bulb and housing, and it worked. (I had learned to be very resourceful when I was younger and had no money.) When I went to the dealership to see if they had the part (several days later), I thought if I don't buy this part, my fix will stop working, and I will never find this part again ... That was about a year ago: My repair is still working. You are correct in observing the the replacement is a bit thicker. I think if I ever have to actually use it, I may have to file the slot that the tab goes in just a bit. TBW
