'98 Expediton Roof Leak Issue

[Eraser74]

I have a 1998 Ford Expedition eddie bauer 4WD with a sliding moonroof & have a few leak issues. When it's raining, a small trickle of water appears by the passenger side grab handle. Sometimes just above the passenger seat is a wet spot or 2 on the headliner. Recently, during a rainstorm, I noticed a larger leak coming out the access panel on the headliner where the moonroof assembly is. I'm at a loss on where the leak is coming from as I've seen it happen on several locations. I read somewhere about drain holes by the moonroof being potentially clogged or disassembled. I have no clue where the drain holes are. Does anyone know what's causing these leaks & how to fix them?

Mine does this to.
I have to push the glass up to make sure it's closed or it will leak.
Try that and see if it go's up any higher.

It lines up fine when I open & close it. I did notice that when it's closed, I can push it down a little & then there's a gap. Is there a way to seal the window or maybe replace the rubber seal around the glass?

Make sure the drain tubes are clear. climb up and look into the channel you will see them. clean all debris from channel also.

Which way do I look into the window to find the drain tubes? Should the moonroof be slid open all the way, vented forward? I'm not sure which angle to look in for the drain tubes. Are the drain tubes small, on the sides, etc. ?

Mine did this, the track,also the gutter for water was cracked. I had to take my track out anf fix it. PIA but it fixed it.
You don't want to leave this go to long water down the drivers side will get into the fuses and electrics.
Check first to see if the water poured from the top with the window open , into the track goes down the drain plugs. They might be just plugged !

 

[dpl200388]

open all the way. you will see holes in the corners. these are the drain tubes. the rear are harder to see cuz of the track for the roof.

 

[Eraser74]

How do I clear them out? Should I squirt water, or maybe used compressed air or some other method?

 

[jdan]

Compressed air should do it. Unless somebody has a good reason not to but I would try it.

 

[Eraser74]

Where are the rear drain tubes. Still having issues finding them. I did locate the front ones.

I have cleaned out the drain tubes on a few Expys. I use a can of compressed air. Please do not use your air compressor as this outputs too much pressure and can lead to popping of the drain lines. I build up the straw of the air can using some masking tape. This will allow you to get a good seal on the opening too as the tape will deform a little bit as you press the straw against the opening. I also use a little bit of water to act as a "hammer" to help push the blockage out. Once you get things flowing, I use a water pitcher and pour about 2 quarts of water through each opening to flush whatever may be left out.

 

[Eraser74]

I found the front drain tubes & cleared them. Still haven't been able to find the rear ones. Does anyone have a pic of the rear tube location?

 

[Canadian Expy]

I don't remember even having rear drain holes

Your roof really shouldn't be leaking that bad, i don't even have the drain track bar in my moon roof anymore because it fell off. The drain track is that cross piece towards the rear section of the room that makes it so you can't close the roof cover with the moon roof open. There is a tolerance for the seal between the roof and the glass seal that you should be in in order for it to seal correctly. I believe the glass seal should be .008" to .012" (inches) below the roof seal. My truck can go through a car wash and it will barely let water in but that's it.

leaking sunroof

hi everyone i had the same problem i found my rear rain trough pushed back in and the rain ran down my visor and i also found the sunroof track broke so i ordered the replacement parts and proceeded to drop headliner wasnt bad but it took me awhile then i dropped the sunroof out of the truck cause inorder to fix track i had to disassemble the whole thing to replace it i then went to the drain lines and yes there is 4 drain lines one in each corner i blew into them and found three was clear but the 4th one i coundnt get any air into it so i thought it was clogged i tried everything and could not get it free so i decided to find the hose running down the inside of the rear door and to my amazment i found the house was pinched between the inner and outer frame i freed it up and now it works good and i put it all back together but my concern is when i close the sunroof the rear middle of the sunroof sticks up higher than the roof can someone send me a picture of the rear of the sunroof closed on there vehicle from the front on a 2002 ford expedition eb
thanks
