Wish I could help a fellow Dutchman. My name is Dirk DeYoung (deJonghe) and my daughter's middle name is Holland. My family came to the US 3 generatins ago from the Ede area and founded South Holland Illinois.
Anyway, I have the same Jeep as you, 2001 Anniversary. As well, I have the Service Manual for this truck, and it is not addressed in the manual.
I would think that the painter could just tape off the window and respray with the glass in tact. That would keep you from removing the rear defrost also.
