2017 Tiffin Allegro Bus Windows stick

Window Latches

How to open a stuck window

I have a 2017 Tiffin Allegro Bus and the windows are very tight and stiff to operate. There is a small plastic pin that is used to “pull” the lock when the window is closed and locked. On my rig these pins break or come off and the window will not open. I have learned that the thin plastic cover, running from top to the bottom in the window center, over the latch and center lock release knob, may be easily pried off at the top and bottom. It cannot be removed since it runs behind the center knob and under the handle used to normally open the window. This reveals the two sliders, one at the top and one at the bottom. These sliders may be operated manually… slide both the top and bottom towards the window center to “pull” the locks out of the slots, freeing the window. The window should now pull inwards and you can slide the window sideways to open.

How to replace a window latch

Once the window is open, you can access the two screws that hold on the window handle. Remove the screws and handle and put aside until later. After the handle has been removed you can easily remove the thin plastic cover that was captured under the handle. Now the latch can be removed using the two screws holding it to the window frame. Note that each slider also has 2 screws holding them onto the latch. No need to remove the sliders.

You will notice the two rods connecting the center knob to each slider. More than likely one of the rods will not be connected. The plastic pin on the slider arm normally goes through a hole in the rod and has a “mushroom” head to secure the pin in the hole. The pin may be broken, or the “mushroom” head on the pin may be broken off, allowing the pin to slip out of the hole. In either case, the knob will fail to “pull” the lock out of the slot making the window impossible to open.

A new latch may be installed by reversing this procedure. I recommend using silicon spray on the sliders and window tracks both top and bottom to ease the window operation. Any rough places may be smoothed using a file. Once repaired use care when opening or shutting each window.

Welcome to the forum.

You are joining a good group of folks here with good information to share. It seems you have solved the problem. Silicon on the tracks is very important. We see a big difference when we spray it on.

Enjoy the adventure!

Also, if you will use Plexus window cleaner as Tiffin recommends the windows will slide easier. Plexus is a cleaner and lubricant.
