So I had slow windshield wipers like many here and I got them fixed this weekend! It took forever to find what would work, but actually changing it out was easy and so much cheaper than a new wiper motor from Toyota.

I used the wiper motor off a 2003 Camry - this model year style (2001-2006) will bolt right up to your MR2 bracket. The earlier Camry motors use a different bolt configuration and won't work.

There are two problems you'll run into:

1.) The arm that bolts on the motor and spins in a circle on the Camry motor has a larger diameter stud that won't bolt to the MR2 arm, and the Camry one isn't bent correctly and won't work. The solution is to get the arm off a 1998-2001 Altima - this is bent correctly and will fit on the Camry wiper motor. You need the bushing to snap over the Altima arm after you connect your MR2 linkage to it - Autozone sells these and then you can get them for $5.

2.) The electrical plug on the new Camry wiper motor isn't the same as the MR2 motor - just splice the plug from your old wiper motor onto the Camry plug. I pulled the correct wires from the MR2 and Camry wiring diagrams and it works perfectly. Here are the connections:

MR2 (BLUE/BLACK) to Camry (BLUE/ORANGE)
MR2 (BLUE/RED) to Camry (BLUE/BLACK)
MR2 (BLUE/WHITE) to Camry (BLUE/YELLOW)
MR2 (BLUE) to Camry (Blue)
MR2 (Black Ground) to Camry (White/Black)

The ground on the Camry doesn't ground to the chassis like on our MR2's so just splice that (White/Black) ground to the MR2 ground wire.

The motor is great and slow and fast work perfect now! Plus, you can find the Camry motor and Altima arm at junk yards or pull-a-part for really cheap! I had tried the remanufactured ones from Autozone and they are just as slow as the bad ones - I'm sure they just plug it in and if it spins it's marked as good even though it is was to slow to be of any use.

Oh, I also got 2 of everything when I did this in case I needed something else, which means I have another complete setup if anyone is interested. I'll even pre-wire the harness so it will be plug and play. Let me know if your interested...

Dracon, totally interested in that second set. We don't have much for good import u-pulls down here in Huntsville.

You still gonna try to make the Dynosty meet? If so I can just pick it up there, otherwise I don't mind paying for shipping. Shoot me a PM and let me know.

Quick correction, the motor in the picture (85110-AA020) is for the '97-'00 Camry. I got one for a 2004 (85110-AA030) cheap on eBay and it's inverted from this one. Not sure if they flipped it on the linkage or what, but while the AA030 will fit on the bracket it won't clear the hood. Gonna head to the yard to raid an earlier Camry tomorrow, should actually be easier to find.

awesome work! i hate my slow wipers. but can you just swap the guts of the motors? there isnt much to them...
I tried this very thing, and I don't recoommend it. There are three spring-loaded commutator brushes, and a bunch of other fragile plastic claptrap shoved in there. You might be more electro- mechanically gifted than I am, though. One of my brushes flew off, and is orbiting Venus right now...

What you can do : slide the black metal motor housing out a little bit ( like a sixteenth of an inch!) and spray a healthy amount of contact cleaner in there. This would have the best risk to reward ratio.

I wish I had found this before I upgraded to my 93 which has much better wipers, but this may still be an improvement, thanks for sharing.

So, which is the correct part number we need to get? I am having this issue now and need to get parts to do this.

Should I be looking for part AA020 (I think)?

Also, does anyone have a part number for the Altima arm?

It was pretty expensive if I remember correctly, around $300-350? I wound up getting a pretty good deal on a lightly used one.
