thought all cars come with a timeout for rear window, so it didn't cook once frost had melted
know my old 96n ford escort did anyway
think it is 5mins, but no doubt will be corrected.
do i assume yours doesn't work?
does it not get hot after a few mins?
do the wing mirrors not get warm either? as uses same switch mechanism
[edit]
have a look here:

even gives a price
bit pi$$ed that it doesn't timeout by default though and apologies for possibly inaccurate info
