Slowwwwww Windows.....
Discussion
Same on my Griff on drivers side only (passenger side is fine), but I have noticed that the rubber in the door that the front edge of the window runs in is a bit knackered, with a few bits coming off it. They are about halfway down, and after the window passes them its fine. Have a look at yours, as I suspect sorting this out would make a fair difference.
It is possible to have 12v but still not enough current to make the motor work properly. Rather than check the voltage I would connect a live/earth straight from the battery and compare the speed both ways. This would rule out any supply problems 100% if you suspect this may be your problem.

Mr Beer will have meant that he was only getting 9V across the window's motor was running. That would have meant that 3 or more volts was getting dropped across the wiring between the motor an the alternator/battery ... i.e. the wiring was inadequate.

And of course there wouldn't be an easy way to change this wiring...? Or is it just the connectors that need cleaning?

The point is that, with respect, measuring the voltage as described is not a conclusive test and therefore not a very good way of fault finding. You could measure it, find 12v assume there is no wiring fault and run off to buy a new motor. If the supply of current available to the motor is low then it will run slowly even if there is 12v there.
The best way to check if there is a problem with any of the associated wiring is to eliminate it. By running the wires direct to the same power source all you have to do is compare the two speeds - no guess work involved.

Agree with above. Also, if there was no voltage drop, motor would not be "working" !! Just accept that the window motor is OK, but it's doing too much work and hence is slow.
Believe you need to look else where in the window mechanism, the cable driving the window up and down. Has that any grease in it ?? I think you'll find that squirting some WD40 over the outer will help "soften" the hardened grease within and you'll see a difference.
A total overhaul will solve the problem - but is it worth it ?? Silicon on runners and WD40 on the cable/mechanisms will "speed" things up.

I was getting 9v across the motor and rewiring has given me back the 12v.So there was a 3v drop along the many metres of high spec TVR wire. Easy to do as you can do it at the plug just before it goes into the door, that wiring is up to it( i assume a Chimaera is the same, white four pin).A couple of relays and you are away, you will have to do + and -. I had been spraying silicon stuff on a regular basis to reduce friction, but this has cured mine.Other terms and conditions apply ! Mine may have been a one off.(nah)
