I need help with a 1991 BMW 325i.

Hi, I’m currently working on a convertible BMW 325i. I’m trying to take out the ac motor so i can get to the windshield wiper transmission so it can be repaired. However I’m having the hardest time. There are 3 bolts on both sides of the motor that I have removed. However i cant get it to budge. What can I do to remove it?
