Water dripping on the drivers side dash by the air vent. I cannot see where the leak is coming from... Is this the running light issue seal? Weird because I see no water entry point... Thoughts?

 

Check to see if your leak is coming from the plug on your grab bar.. Chances are your marker light is leaking and water is running down and coming out of that bottom plug on your grab handle, as that was a Senerio I've seen before

 

most likely a center marker light leaking but it could be the end marker too.

ive had mine leak and had to fix them. not really a big deal, i used a coat of silicone on my rubber pads but you can buy them too if needed. mine were all in 1 piece so it wasnt too bad. I also had to get mine sealed quickly and couldnt wait for them to come as it was leaking in mine in the slightest of rain.

I wil check it tomorrow... Thanks!

 

the easiest way to check the center 3 markers will be to pull the headliner cover off. the caps can feel tight but will still leak and it is really hard to tell which one it is.

let us know what you find out.

It warmed up enough in Denver to where I am going to attempt to locate and fix the probable leak. I bought some silicon and am going to seal all the lights above the cab. I will report what I found tomorrow.

 

Update: I removed the five marker lights above the cab and noticed that the two outside ones (on the rails) were loose and probably leaking. The middle three were more secure; however, when I removed them I noticed dirt inside the middle marker. I siliconed all of them, secured them with painters tape and they are currently curing.

 

UPDATE: I went through the car wash and the water leak's still present. Not sure where to go but I am going to remove the drivers side plastic post cover and start form there...

 

Can you take some pictures of what you do. There are certainly a few thousand hummer owners who have the same problem ...

 

Camera is a great idea... Unfortunately, I just put it back together - here's what I did:

1. Leak coming from the drivers side on air vent
2. Previously removed and resealed all lights above cab

Update (All on driver side):
1. Removed amber running light and noted seal was wet
2. Removed side rail and rear red light
3. Under front amber light noted that the rubber wire plug was wet
4. Cleaned, siliconed and reinstalled rubber plug (FYI - There's only one plug).
5. Cleaned, siliconed and reinstalled amber light
6. Reinstalled rear red light

Not sure what else to do. I noted that the drivers side door seal could use replacing and am going to order this week. I'm tempted to stop by the dealer and ask the service department if they've experienced this...
