How I replaced my fogged window

For the last few months I've been attempting to decide if removing and replacing a fogged window on my 2007 Holiday Rambler Neptune was something for me to tackle. The fixed pane in the large combination fixed and sliding window assembly is badly fogged. I obtained a replacement for the fixed pane from Monaco parts a few months ago. Then after reading a few posts suggesting this was a job requiring professional experience I almost decided to turn it over to one. When I spoke with the shop I had chosen I found the owner willing to spend time explaining to me in complete detail how the window assembly is built. He was more than happy to do the job for me, but with his advice I decided to get out the tools tackle it myself.

After several months of indecision the entire job took less than two hours and my new window is installed with the price of the glass my only cost. My step by step follows for anyone considering this task.

First step is to remove the window shade and valance to give access to the window frame retaining ring. Locating and reaching the two screws holding the valance to the overhead cabinet was one of the more challenging steps of the entire job.

Remove the screws holding the retainer and carefully lift off the retainer. It's split at the top so could be bent or damaged easily. Open the sliding panel and grip the window frame while pushing it out a bit to break the seal around the outside rim.

Next get your step ladder in position and gradually work the frame loose from the outside. The seal used by Monaco is rubber encased foam so it stays attached to the window rim. It is not adhered to the side of the coach so the frame is fairly easy to work free. The frame assembly including the two windows is heavy so be careful lifting it out while on your ladder. I did it without help, not a problem.

The two screws holding the center verticle bar, and the four screws holding the split frame reinforcing strap are covered with a rubber calk or sealant. The screw heads require a # 20 star bit to remove. The rubber calking material must be removed before you can get the driver tip into the screw head. Exacto knife and patience for this part.

Once the strap holding the split frame together, and the screws holding the verticle bar, are removed the frame can be spread apart allowing the old fixed panel to be removed. Next slip off the rubber channel from the old window and place it on the new one. Before fitting the new window into the frame I sprayed some silicone lubricant into the frame channel.

I was paranoid about weakening the seal on the new window to I was extra careful handling it at all times. With the silicone in the frame channel the new glass slipped in without difficulty.

Now it's just a matter of reversing the process and you're in business.

Barrys, Thanks for the Great info. I need to do a smaller window in bedroom but put it off. I will tackle that job now.

I was advised that any petroleum product used could cause the seal of the window to fail. This was grounds to void my warranty, So to lube the window track I had to find a non petroleum lubricant. I finnaly found spray graphite to spray on the molding (carefully) JMHO (Food For Thought)
