Window rolls down slowly

[Lothsahn]

I've noticed that the windows in my Leaf seem to roll down quite slowly--more so than other cars. I never thought too much about it until my driver side window stopped working. I replaced the window switches and that fixed the problem, but I'm wondering if the motor is having to work extra hard and it fried the switch.

I timed the window, and it takes 3.28 seconds to fully roll down, which isn't too bad. However, it takes 5.82 seconds to roll up. Is this normal for Leafs, or is mine slower than the rest?

I tried cleaning out the track as shown in this video but it didn't seem to help: https://www.youtube.com/watch?v=-CE5y3D4OMw&t=246s

Any thoughts? Should I be concerned?

My 2012 nissan leaf windows had the same problem, i cleaned the window and i try everything and while it helped it wasnt much difference, the window in the prius is really fast by comparasion, what i discover was nissan in order to save money they installed really small dc motors so because they dont have lots of power they need to rotate more times so it just takes more time for the window to roll up, is just cheap low quality from nissan the motos wont last long either.

Windows on my 2011 were much slower than the windows on 2015 and 2019. The windows on the 2011 were really slow when ambient temperature was low, but I never had trouble with the motors--they were still working fine at 3-1/2 years and 50,000 miles when the car met its demise.

I'd think it normal for raising to take longer. The little motor is having to lift the glass against gravity.

you need to clean the inside of the track where the glass goes.

Then use PTFE lubricant on the INSIDE of the track..

here is the stuff..

Yeah, as stated in the OP, I did that and it didn't help.

Thanks for the feedback, Gerry. I'll assume that this is as designed (especially since it's slow on both sides) and just leave it as is.

Thanks!

The switch is simply providing CAN signals to the encoder that is coupled with the window motor. Motor current does not pass through it.

Ah! Good to know! Thanks!
