2006 H3 Adv and Lux, 77k miles. My moonroof works fine, but it makes a loud squeak/rubbing noise when closing (almost like nails on the chalkboard). I live in a hot summer/cold winter climate, so I am sure I have winter debris that got in there somehow. I have tried cleaning the tracks and lubricating it with silicon spray, but I must be doing something wrong. Any tips out there for how to clean that out and lube it? Thanks!

 

u really gotta get up and see if the glass is dragging on the roof metal.
close,get a light look in back?anything?do same with it open.

not ez to see in back

4 bolts ? takes out the window!!

 

I'll check it out. Thanks for the tip!

 

Is your forum name after the Ratatat song by the same name?

 

No, actually I'm a motorcycle freak in addition to the hummer, so that's where the loud pipes come from.
