not the usual window issue!!!

[ttmedical]

This sounds an awful lot like a microswitch error in the roof mechanism. Particularly because the window is dropping three inches (like when you try to put the top down) and that it is happening bilaterally. I'd start my investigation there. Not sure what the proper diagnosing strategy is but the symptoms really do sound an awful lot like that microswitch is the culprit. Google or search the forum to get an idea of the part I am referring to; might help to call it the 'roof microswitch'. If this is indeed the problem, replacement would be a quick fix (but trying to fix the microswitch may be the cheapest fix). Hope this helps!
