Single windshield wiper mod Mr2 7 Years, 4 Months ago Karma: 129
This modification will allow you use the OEM passenger side wiper to fully wipe the entire windshield and store in the stock location when not in use. This is a fairly easy mod to perform that will take about 1 hour using basic tools.

Reminder - what you do to your car is your business and I take no responsibility for any work that is performed from following, or not following these directions.



1. Remove the black plastic caps at the base of each wiper arm and remove the 12mm nut holding the arm to the swivel assy. Remove arms and discard the drivers side (left side of car), we won't be using it again.



2. Remove the two outer plastic caps on the black wiper cowl; remove the 11 screws and then lift off the cowl.



3. On the passenger side pivot assy., you will see that there are two tie-bars that are attached to the pivot arm. Remove the two retaining screws; one will be facing up, the other down. You may need to use a right angle Phillips screwdriver or a pair of pliers to get them loose, as the area is fairly cramped to work in. Now, using a flat head screwdriver, carefully pop off both Teflon swivel joints from the arm.



4. Now you can remove the 3 10mm bolts that hold the drivers side pivot assy. to the body and remove the whole assy./tie-bar from the car. You can also discard this piece; we won't be using it again.



5. Remove the 3 10mm bolts that hold the passenger side pivot assy. to the car and remove it also.



6. We will now perform the mod to the pivot arm that will increase the range of motion of the passenger side wiper from 90 degrees to about 145 degrees, which will allow coverage of the entire window.



7. Using a die grinder, grind the mushroom on the backside of the larger swivel ball, flush with the arm. Use a punch to pop the ball from the arm, being careful not to damage the ball.



8. Carefully measure exactly 9/16" from the center of the existing hole toward the wiper arm attachment stud, and center punch a mark. It is extremely important that this measurement be precise and exactly centered on the arm, for the wiper to function properly.



9. Drill a 5/16" hole through the arm. You may want to start out with a smaller pilot hole.



10. Press the ball into the new hole; making sure it is on the opposite side of the other ball. You may have to do some filing/fitting to ensure it seats fully onto the arm. Tack weld the backside of the ball, to prevent it from moving or coming loose from the arm.



11. The pivot assy. can now be reinstalled back into the car. Reattach the tie-bar from the wiper motor and install the retaining screw.



12. At this point, you can temporarily install the passenger wiper on the car at its normal resting position, turn on the wiper and verify it is operating properly and not binding up anywhere.



13. If everything looks good, you can reinstall the wiper cowl and permanently attach the wiper arm. You can fine-tune the resting position of the wiper by moving the arm left and right on the splined stud and than finally attaching the 12mm nut and the plastic cap.



14. Enjoy your new single wiper!

That is a sweet little mod. Two questions:

1. Any vids of it in action?

2. Do you reckon you could switch the polarity and then swap the arm over so it's resting position is under the driver's view? Just so it's the driver's side that gets wiped first

" Do you reckon you could switch the polarity and then swap the arm over so it's resting position is under the driver's view? Just so it's the driver's side that gets wiped first "

Thats easy done on the back of the wiper motor itself there is a rotating arm held on by a 12 nut .... Simply remove the nut and rotate the arm 180 degrees put back on the nut and it will change the direction of the wipers ..or rest position ...in effect the wiper motor is now pulling the linkage instead of pushing it ....

I had the problem of my wipers going down first then up and that was the cause of my problem ...

I'm not convinced. It looks kind of cool, but after the novelty has worn off I would want my regular wipers back.

Mercedes had a better way of clearing the windscreen with a single wiper.

It did not look pretty, but cleared more of the glass. It used a cam to allow the blade to cover a larger area.

Look it up on YouTube to see how the motor works.

did this wiper mod myself today, and took pics to make it easyer for everyone else to understand.
the big swivel ball has to be taken out so grind down the back side of it and hammer it out.

it said measure 9/16 whatever that is, so i converted it to normal units of measurement and got 14.2mm, it seems to be a bit much so i think 12mm would have been better,
anyway measure 12mm from the center of the existing hole toward the wiper arm attachment stud, and center punch a mark.

drill a hole with an 8mm drill bit, put the ball back in, spotweld it in place and put everything back together.
