Only way I can open/close the sunroof is manually. Just bought the car. When I push the sunroof button to open or close, I can hear the motor turning but the sunroof doesn't even budge, like the motor isn't hooked up to it. Is this possible? How can I check it? Do I have to take the headliner off? BTW, the car is an 86 CRX SI. Thanks guys, I'm sure you can all easily help me.
