I put a light coating of silicon on the barbs and just some small zip ties. It is secured in other areas with zip ties as well. Also put a dab of silicone on hose to the old run to firewall.

To be proactive on the driver side looks like I might be drilling a hole in the floor somewhere.... follow up metal protection of course

I wonder if these are some floor grommets I could leverage here for driver side drain?

 

I would just keep the factory holes, it lasted for almost 15 years before you had issues.

 

I may just get the new stock firewall piece for the driver side... passenger side ..train has already left the station on that mod but no new holes drilled

It sounds like the driver side one is easier to extract and swap.

 

I'm gonna do the straw and updated drain plug/grommet on the driver side

I typically check my sunroof drains a couple times a year. I hadn’t done anything on driver side since my 2021 posts above.

I went to test drain on driver side on a hot day and noticed water didn’t seem to be coming out bottom of car. Ok.. where was it going.. then started to see a few drops showing up on the driver floor mat.

Quickly popped off the A-Pillar trim and saw it was coming down from sunroof drain.

Dropped headliner enough to see that drain line had shrunk and pulled off sunroof drain. Just have to remove the ceiling hand grip to pull it down.

Cut off existing end, reattached and added a zip tie.

Add a 2 inch line extension in the A-Pillar using some parts from the other repair.

I’ll probably pull down trim to look at condition of passenger side where drain attaches to sunroof before fall.

 

Ordered two full replacement drain lines from Megazip for front drain lines. Even with costly shipping half the cost of what it would be in US.

Replaced the drain line from passenger line of my previous fix today. I plan to replace the drive side hose soon with replacement I purchased and Y into the large HVAC drain line that passenger goes into so I never have to worry about sunroof drain blocks beyond the actual sunroof assembly
