My del sol windows all work great, but the passenger side one seems to struggle when it rolls up, I am not sure why or what is causing it, but it goes, then slows down, then speeds up, slows down and then goes up to the end... kinda weird... anyone have any ideas?

 

Your window motor is probably just getting old. They tend to slow down with age. All of mine are slowing down a bit. The driver's side one does exactly as you describe, I assume because I use it the most. Greasing the side tracks might help. I forget which grease would be good to use without leaving alot of residue/streaks on the glass.

 

'Honda Shin Etsu' for the seal works wonders.

A quick Google for 'Honda recommended lubricant list' will net you another site with a fine list including part numbers - G'luck :-)

 

SELLING A DEL SOL WINDOW MASTER SWITCH JUST IN CASE

 

Any tips on where to grease the track or how its done, I have shinitsu grease laying around still.

I do not need to lube the seals. They are lubed, the window going up / down on the passenger side is just slow then fast hten slow.

What part is this?
