I took air pressure thru the holes on side of the sunroof. Work for a minute .

 

I have the same problem. After a long search I figured out the sunroof drain tubes aren't draining like they should. Water is coming in my interior lights and dash area, flooding my floors. Also have some water under back seat that fried my amplifier so I have no sound in my speakers. I'm hoping to borrow an air compressor to blow out the drain tubes. If that doesn't work I'll be pulling down the headliner to check if the tubes are not corrected somewhere.
