I used some weedwacker line and stuck it down the front drains a few feet. Didn’t really notice any clogs. I also put soapy water on the windshield edges and used a leaf blower from the inside to see if there was any noticeable leaks and none found (I hope).

 

Dumb question, where does the sunroof drain "exit" the car? Like where does the water drip/run out?

Will add this to the regular maintenance, but would like to understand where teh drain line runs.

 

It exits through the frame somewhere by the front part of the door. It’s hard to pinpoint exactly, but you will see it drip.
