5. Operation
The Dorman 748-295 Power Window Regulator and Motor Assembly operates in conjunction with your vehicle's existing power window switch. Once installed, the window should respond immediately to switch commands, moving smoothly up or down.
- Up/Down Movement: Pressing the window switch up will raise the window, and pressing it down will lower the window.
- Automatic Function (if applicable): Some vehicles feature an "auto up/down" function. If your vehicle supports this, a full press and release of the switch will cause the window to fully open or close without holding the switch.
If the window does not operate smoothly or makes unusual noises, refer to the Troubleshooting section.
6. Maintenance
The Dorman 748-295 Power Window Regulator and Motor Assembly is designed for long-term, maintenance-free operation. However, proper care of your vehicle's window system can help ensure its longevity:
- Keep Window Tracks Clean: Periodically clean the window tracks and rubber seals to remove dirt, dust, and debris that can impede window movement.
- Lubricate Seals: Apply a silicone-based lubricant to the rubber window seals to keep them pliable and reduce friction.
- Avoid Obstructions: Ensure no objects are obstructing the window's path when operating it.
