My windows were pretty slow in the summer time, and now it's winter and they take tooo long and slow to close. They are very easy to open, but barely want to come up. Will putting new regulators in help the situation?

probably not, the tracks are probably super dirty, as mine were straight filthy

i used about 100 qtips coated in silicone to clean mine out. my spirit gave way and i stopped after the dirt just kept coming. that being said they are alot better now

in all honesty the motors are more of the fail point in most cases.

Get a can of spray silicone lube, put down all the windows all the way, spray a sh!tload into each track, put them up and down a couple of times.

Should run like new or better.

Earlier this week I was lazy, cold, and without a snow brush, so to clear the snow off my windows I rolled them down and back up. They were all reluctant to come back up (not that big of a surprise during Canadian winters); but the driver side one would only come up a few inches before it gave up and rolled back down. It took three tries -- with me helping it up -- before it'd fully close. At the time, I shrugged it off and told myself "I just won't use the windows in the winter".

I do remember doing this with my '03 shortly after I got it, but this is the first winter with my '04 and it completely slipped my mind to try this until I came across this thread. I finished off the half can of silicon lube I had into the tracks for all 4 windows. They're still a bit slow (actually, probably "normal" speed for -20C temperatures), but they're all way faster and show no sign of "giving up" like they wanted to before.

So yes, this certainly helps out. At least it has in the two Pathys I've had. It obviously won't fix bigger problems, like failing motors, but at $3 for a can of silicon lube it's a cheap fix to try.

Check to see that the windows in question go up and down squarely with the frame. The amount of torque the motor produces is about equal up or down if the frame pull and lubed areas are OK, but going up may take more because of the weight.

Before doing any spraying of lubricants down the side slides use clean compressed air to help remove crap, dirt and dust if you have access to a compressor or used compressed gas that is available in small bottles.

Silicon sprays are so so, but you must remove the dirt first. With very hesitant windows the use of a bar of ivory snow soap acts as a good lubricant if you take your time to get a very little each side of the edge of glass.

The worst in amount of labour is to take off the inside panel and clean all the old grease add new grease and clean the friction slides...but a warm area is needed to help with your comfort in doing this.

The car makers know this is a bad area and install self resetting breakers to protect the motor and wiring instead of fuses.

i have changed countless window motors and regulators. generally i change them both at the same time. however given a case of slow windows it could be one or the other or both.

how many have you changed specifically on an R50?

it's a known issue on R50s, and the vast majority of the time, it is just a case of dry tracks/guides.
