Sliding window not opening (Diamond Sea Glaze)

[Thomas B.]

Hi- on our 2005 R21, the starboard side front sliding window will not open anymore, despite all efforts.. It is, as far as I know, a D15 Diamond Sea Glaze product. The company has not responded to my enquiries. Does anybody know how to solve this problem? It would be appreciated.
Thanks,
Thomas

I experienced that issue on my EC21 with both sliding windows and finally managed to open them with GREAT difficulty. I now use a spray silicone on the weather stripping channels and have never had another problem. They glide very smoothly now and never stick. You might try the silicone spray on both sides of the window channel while it is stuck to see if that will loosen the window up. The silicone spray should be able to seep into the channel, saturate the channel and losen it up. I bought the spray at Home Depot. Forcing the window can cause GREAT problems possibly breaking the glass, bending the frame etc.
Good luck with this very frustrating issue.

I have had folks recommend the use of Pledge polish over silicon spray lubes. I haven't tried it my self so I don't know how well it works, or not.

Mine do that too, what I do is, I shut the window until it locks, then pull on it without unlocking the handle so that it goes against the lock. Everytime I do this, they open easily, without any product. If I foret... it takes lots of pulling to open them!

The handle has a slight 'hook' at the locking edge. Try pressing and holding the handle in towards the glass to unlock then move the window forward slightly to release the 'hook'. Then slide the handle/glass towards the open position while holding the handle against the glass.

That "hook" on the latch catches a lot of people, until you figure out the push-pull routine. We used Mary Kate Liquid Rollers (designed for use on your trailer bunks to keep them slippery) in the window channel, top and bottom - it does not collect gunk like some silicone sprays can do.

If you use your boat in saltwater, the salt-spray will collect in the tracks, making them sticky. Using a mixture of vinegar and water in a spray bottle, liberally applied to the window channel will help keep them salt-free, and less prone to sticking. Vinegar has plenty of uses onboard, including a good way to dissolve the salt streaks on your forward helm windows - makes it easier for the wipers to do their job.
