1. Window Switch:
>- Check the power window switch on the driver's side door; it may be faulty or have loose connections.
2. Wiring Issue:
>- There could be a break or short in the electrical wiring that controls the window's up function.
3. Power Window Motor or Regulator:
>- The power window motor or the window regulator mechanism itself might be failing or damaged, preventing the window from going up.
4. Child Lock:
>- Ensure that the child lock switch is not mistakenly engaged, especially if only the driver's side window is affected. It disables window operation except from the driver's master control switch.
