Window Issue

[Tazman]

I recently replaced the weather striping around the windows of my truck. The drivers door has started having a click when at the half way point going up. In doing so it pushes in the striping on the post so it is not where it belongs. I am wondering if the window is not lined up correctly. Is there a way for checking this?

Thanks

Did you replace window felt on all four sides? Is the dr panel still off, use flashlight and watch as you roll up, see whats going on right where it clicks, could be the tracking unit.

Yes all the weather stripping was replaced. Did not have an issue until a couple weeks after this was done.

Most likely the window regulator, as stated watch it closely as you roll up the window.  Something may not be lined up right. I'm sure you' ve seen the regulator...

More often than not, "clicking" originates in the regulator gear.  Nonetheless, are you sure you completely seated the new felts into the channels?  Check that the glass isn't so loose in the channel felts that it cocks sideways or tries to jump out as it moves up and down.  Make sure you don't have a loose or broken channel bracket.
 
Going from memory - the forward channel has no adjustment.  It simply bolts to the inner panel to make it stationary once the vent window assembly is secured in place.  The rear lower channel has a fore-aft adjustment at its lower extremity plus a limited vertical and side-to-side adjustment at its top where it aligns to the fixed upper door channel that's integral with the door.

Loosen the two bolts that retain the rear channel to the door and raise the window about half way.  This roughly centers the glass between the upper and lower channel halves, aligning the two halves to one another.  Tighten the upper bolt.  Next, drop the window to within about 1" of the lower stop.  Push the bottom end of the lower channel forward as far as it will go, forcing the glass all the way forward into the front channel.  This removes all of the fore-aft slop in the glass.  Occasionally there isn't sufficient forward adjustment to remove the fore-aft lash in the glass, and you will need to bend the channel bracket slightly to make up the difference.  Tighten the lower channel bolt. 

Pick up some "dry silicone spray" such as CRC 05074 Heavy Duty Silicone, or PB Blaster "The Dry Lube" and thoroughly wet the channel felts that contact the glass as it moves up and down.  Be forewarned that "dry silicone lubricants" may leave a whitish residue that can create a disagreeable appearance, so spray the lubricant on a test surface and let it dry before lubricating the channels.  That way you can decide whether the look is acceptable.  In addition, make sure the sash tracks and rollers are adequately lubricated with heavy chassis grease or GM #1052196 Lubriplate Type A white body grease.  Finally, test roll the window up and down while checking for bind and tweak the adjustments as needed to provide the best result.

If you have power windows, you should consider installing relays to overcome voltage losses through the factory harness.  There is a good write up on the Forum from one plus years ago, or so, by frotosride.

Oh!  And, watch out for razor sharp metal inside the door!  Keep your hands out of the door when actuating power windows!

Huh, i recently did all my felts and didnt notice the rear channel was adjustable. Were they in the 77's??

I did the drivers side window and man it made a big change. The window works as good as it did when new. Will do the other this weekend.
This is why I tell every square body owner about this site, it is the best!!

Thanks

Glad to help, but what was the solution?  Seating the felts?  Lubrication and adjustment?  Regulator replacement?  Adding power window relays?

[Tazman]

Lubrication was that was needed.

Great!  The less it costs, the more rewarding.
