First of all, is this normal for the windows roll down while I press the roof button?
It doesn' matter whether I close or open the top, the both windows still roll down.

Most times my roof button is working, but sometimes it doesn't..
where do I have to check??

 

for one, all windows roll down when going up and down, at least mine does.

second, make sure your e-brake is pulled up when rolling up or down the top.

 

the window thing is normal. It prevents the roof from breaking the glass if the roof is slightly off in alignment. Nifty feature. I damn near broke the passenger window on my old Celica GT Convertible because the top was warped ever so slightly.

oh yea that makes sense!
I was so stupid ha ha
Thx guys!

 

Don't worry. Salesman made the same mistake on my test drive. I had to do the test drive with the top up the whole time.
