Fleetwood Discovery Replacement window

[firecoop30]

I have a 1998 Fleetwood Discovery 36T. The drivers side window is foggy between the double pane window. I'm assuming the thermo pane has lost its seal. Anyone know how to fix this? Do I have to replace the entire window?

Thanks.

You can replace the window or you can go to a glass shop that specializes in repairing dual pane glass. One such is Suncoast Design Center in Hudson Fl. 727-868-2773. I believe they charge $200/window.
Depending on the window size, you may be able to buy a replacement for $250-$300 and install it yourself. You could check with Fleetwood Parts to see what a replacement will cost.
