Hello, I have a 2004 Toyota corolla when I'm using the power windows to raise the window up I see my headlights dim a little but when lowering the windows it does not dim at all is this normal? if not how can I fix this problem? thanks

The window motor has to work harder when raising up because it's working against gravity. The motor may be wearing out and pulling a bit too much current. Also check your battery and your alternator, and check grounds. Spraying some silicone lubricant down the window channels may help a bit.

Check your alternator output.  It could be going out, soon.
