up and down revs

[crate]

hi guys

about a week ago my 33 started clicking from the right hand door ,

so i pulled the trim off and found that it was comming from the white box that has something to do with the electric windows,

now the strangest thing is that it will click every 10 seconds twice .with every click the engine revs up and down ,not much but enough to notice it (say like when the aircon is turned on)

does anyone know what this little white box does in the door

and how it could be afecttting my revs

I have no idea why it is clicking but it will be switching the electric window motor on and as the window is up (or down) it is pulling about 10amps and loading up the alternator, causing the revs to fluctuate slightly.

Try tapping the passenger window up switch with the window already closed and it should have the same effect.

As for fixing it, maybe have a look for a short in the wiring, or swap the unit.

thanks for the reply bhdave

i pulled apart the electric button unit .and found that it ha s a crack on the bottom of the up and down switch ,which since has broken (due to my clumseness) and has made it stay on the up position,so it looks like ill be lookin for a new unit this weekend

thanks for the info

Hey my door motor started doing exactly this about 3-4 days ago. It doesn't happen all the time but i'd say a good 50% of the time the car is on, weird! Another problem i've been having is sometimes the up/down button doesn't work so I just open/close the door and it works fine, probably related no doubt.

I'll pull apart my door trim tomorrow and see if their is anything obvious wrong otherwise it's off to the Auto Electrician for a 2nd look at it.

If anyone has a perfect working driver-side motor for sale pls PM me.
