I have a 2000 ml and the drain tube on the passenger side for my sunroof has wonderfully disconnected, anyone have a fix, as the access sucks. Have done multiple searches on the forum and the web but no joy.


Thanks

You really don't explain your problem, you just say that the drain has become disconnected.

What is happening? Are you getting water inside the truck? If so the drain has just become clogged. Open the sun roof and pour a small amount of water into the channel at either end and see which one does not drain.

Then you should buy a spool of plastic weed whacker reed and insert it in the hole as far down as possible. You will know you cleared the clog when you see the water on the ground near the front or rear tire.

Front drain or rear? If you search there was a thread within the past 6 months or so about accessing the front drain tube. IIRC all that was involved was removing the interior trim on the A pillar.

If it is only a matter of cleaning I use the method 43sqd mentioned. Weed Eater line or very heavy fishing line.

Sorry if I didn't explain myself, the drain tube on the passenger side footwell has become disconnected from the elbow that exits the vehicle at the fender, water enters the vehicle and there is no clog. You can see the disconnected hose but unable to fully reach because of access issues relating to the blower motor and ventilation system. I did an extensive search but was unable to find a thread that showed how to access this.

Any help or link would be appreciated.

thanks again all!!!

It is still not clear what you are talking about. Look at the diagram in the pdf which shows that the drain hose #35 is a one piece item which runs from the top of the sliding roof inside the A pillar and drains outside between the fender and door.

The diagram does not show an elbow and a continuation hose. Maybe you can take a photo of the elbow you are talking about.
