'94 sunroof problem

Hi,
My CRV's sunroof acting wierd. Someday, sunroof just turn itself on and drain all battery. I can't start the engine. I changed battery just a few month ago. Now, I have to jump start about three times a week. Anyone know the problem? Thank you very much.

Hmm well the first sign may be that they didn't make a 94 CR-V. Secondly its probably aftermarket since the first started putting them in around 02 i think
