The Window Regulators/motors are starting to show their age.
All the replacements seem to cheap Chinese knockoffs.
Question: Wait till they die or replace now?
If so where to get replacements?

 

much better to replace now

 

you can probably get more life out of them if you CLEAN and lube the track or slot that the window rides in on both left and right side...
Honda sells a lube that they use specifically for that, but you can use white lithium grease, or a silicone spray
make sure you clean them good before lubing - if you dont then the lube will collect any dirt or dust that may be in there and will act like a paste... it will stress and slow the window motor probably more than it originally was.
You have to excericse the window regulators...if they sit for a while without being used they tend to go bad sooner...

I have noticed that majority of window regulators I replace are on the passenger side, because they're used less frequently...this is just my opinion

have fun
