The Active Aero on my VR-4 doesn't function properly at certain times.
How do you take the Active Aero motor out and clean it?
Remove plastic trim panel on rear hatch. There are a few screws and
snap clips. After the screws are removed, pull gently wherever a clip
Remove bolts on rear wing. There should be 3 in the middle, and 2 on
each side. Then disconnect the wiring harness and remove the wing.
Turn the wing upside down and disassemble. The motor is in the
middle inside the "third brake light". Also remove the actuator tubes
since the motor is acutally attached to this. Note that there is a
small removable retangular plastic piece with a metal pin. Don't lose
it and remember it's orientation.
Disassemble the motor. There are 4 bolts holding on the cylindrical
armeture cover. Clean the brushes and armeture. I used a little "TV
Tuner" cleaner from Radio Shack. I put a little lithium grease on the
gear and shaft, but too much might gunk up the brushes.
Reassembling the motor is the most difficult part. Reinsert the
armeture so the gear engages properly. You'll have to pull and hold the
brushes open so it drops completely into place. Next, drop the ball
bearing into the cylindrical cover. Use a straw (the fat milk shake
type from McDonalds) since the cover has strong magnets that will snatch
the ball bearing before it gets to it's home. You can drop the ball
bearing through the straw to the bottom of the cover. Now, keeping the
cover with the opening on top, drop the armeture assembly into the
cover. You have to apply a little rotational pressure on the armeture
so it doesn't slip out. Hopefully, the ball bearing will remain in
place, the armeture won't fall out, and the brushes will stay in place.
Plug in the motor and test. I used a batter jumper cable to ground
the motor housing to the car hatch. Insert the key, and activate the
aero switch, the left most toggle position. If the motor works, your in
good shape. Make sure the motor is in the "down position" when your
done testing and you unplug it.
I also greased all moving parts on the wing. I removed the actuator
cables from their tube and greased those as well. (I noticed that the
cable is thick and spiral wrapped with a plastic cord. The plastic
appeared to be worn, but it hasn't failed yet.)
The next tricky part is getting the cable at the correct position
before you attach the motor (the motor has a gear which contacts the
cables). I think I installed the tubes without the motor attached.
Make sure the wing is in the down position to match the motor. The ends
of the cable have a small hole that a metal pin fits into. Slide the
cable in or out until it fits over the pin, now the cables are in the
