Maintenance Inquiry: Excessive Resistance in Driver's Side Window Regulator - Kubota RTV 1100C

[Joel P]

Hi All :driver's side window exhibits a significant amount of resistance when being rolled up. The effort required is substantially greater than for the passenger side window.

I would appreciate any recommendations regarding the standard maintenance procedure for this system. Specifically, I am inquiring if there are any specific internal points or guide channels that should be lubricated, or if there is an adjustment procedure for the window regulator or sash that should be performed to correct this stiff operation.

Thank you for your time and professional assistance.

Welcome!

I don't know your particular vehicle, but I think you'll find there's a panel that can be pulled off, and the guts of the mechanism will be pretty obvious. Window mechanisms are pretty simple and pretty much common. There's likely a track that can get gunked up, and the lube points should be evident.

It looks like there is an exterior door panel that is held in by a rubber gasket. Maybe someone who has done this on your vehicle can chime in.

generally speaking there's two areas for 'binding'. 1) the window assembly, 2 the crank assembly

if you disconnect the window from the crank, you should be able to easily slide the window up and down, If not then the 'binding' is in the channel/ window alignment. could be bent, twisted,warped.
If the window move nice ,then the crank/arms must be binding. Inspect how the linkages are supposed to move, see/feel where the binding is.

considering the environment these machine are in, it's kinda understandable stuff binds up.
