420 sundancer vent window doesn't work

[Greg Brophy]

Folks,

Looking for suggestion on a vent window that stopped working on a 420 Sundancer 2005. It acted up at beginning of the season and then just stopped working. Is it a common problem and who has the best parts selection?

small linear actuator - just take it apart and lube it up - sometimes just spraying wd40 in it and "exercising" it does the trick - otherwise determine the size and stroke and order one off amazon or ebay

Lots of us have had this issue. I spray the actuator rod (and all the other parts) with white lithium grease and exercise it by having someone push the toggle switch on at the helm while I manually move the vent glass up and down. That usually solves the "sticking" problem for a long time.
