Thanks for the input everyone.
ulitmately it was the #a fuse controlling the rf and lr windows. the wierd thing is that the fuse looked fine except for some wear on the end caps. that is why my visual inspection didn't turn up any thing. but that is an excelent point about the window switches. when i first got my 300d none of the switches worked consistantly and some not at all. i removed all the switches, cleaned the contacts with emery paper and like magic they all worked. keep this in mind future generations.!!!!
