A 355nation How To presented by

Project Name
How To Change out a windshield wiper motor

Project Description
Removing the windshield wiper assembly to change wiper motor then reinstall

Skill Level
Moderate

Project Vehicle
Make: Chevrolet
Model: Colorado
Year: 2006
Engine: 2.8L
Power windows: No
Sun Roof: No

Tools Needed
-Wrenches 5/16, 1/2, 5/8
-10mm socket
-Wire cutters or Trim removal tool


Project Time
1 hour or less

Project Cost
$117 at Autozone


Step 1. Remove windshield wipers by removing nut caps and with a 5/8 wrench remove the nuts. I used the wrench to pry up on the base of the wiper to remove it.


Step 2. Remove 6 retainer clips on the front side of the wiper cowl. When removing wiper cowl pull straight up because there are retaining clips on the back side bottom of cowl.




With the wiper motor assembly being on the driver side you can just roll the cowl out of the way but if you choose to completely remove the cowl you will need a 5/16 wrench to remove the antenna

Step 3. With the wiper motor located. Remove the wiper motor retaining bolts located on each end of the assembly with a 10mm socket





Step 4. With assembly bolts removed rotate assembly clockwise and up to remove from cowl area. I was by myself when I did this so the hood is still on. It's much easier with the hood off but can be done with hood on.



Step 5. Unplug wiring harness. Its located between the master cylinder and the fire wall. Once unplugged feed the wire through the firewall.


Step 6. With assembly removed from the truck, remove the connecting arm nut (1/2 wrench) and 3 motor bolts (10mm socket)


Once old motor is removed, install new motor in reversed steps.



I almost forgot when installing motor make sure that the connecting rod is on the passenger side of the motor like shown. If it is pointing toward the driver side your wipers will work backward (I found out the hard way lol). I had to pry up the cowl to get this picture.


Thank you and good luck

Heading to junk yard....

Hey all, heading to the wreckers today. Going to be looking for a wiper motor and hopefully multifunction switch. Any ideas on compatible parts? I think Canyons work and maybe H3's.
Also going to try and get anything else I may need in the near future.
Much appreciated!

No matchy on the wiper motor for any vehicles that are even close to the same platform. The part numbers only show up as being compatible for the colorado/canyon/izuzu's

Sorry bud!

Multifunction switch is a little better story though!

You need to understand that the only way you can pull one out of an H3 is if you already HAVE cruise control. The H3's did NOT come WITHOUT cruise control, so as long as you already have cruise you can pop one out of a Hummer or any other colorado/canyon/izuzu.

Re: Heading to junk yard....

Thanks Colby, I do have cruise but am probably hard pressed to find an H3 at the local junkyard.
I found a "Universal" motor online however I am hesitant on the "universal" part. Say some mods will be required to fit. I'm searching eBay now, I think that'll be my best bet.
Thanks again for the parts listings. Hopefully I can fix this soon.

I would say your best bet would be finding another colorado/canyon to pull the wiper motor out of. If you can't find one let me know...there is 3 colorados in the local yard here.

Re: Heading to junk yard....

I'm just looking on eBay right now, getting to the yard has proven difficult since the roads are pretty messy here. I'm in Alberta, CANADA. Seems like the only place I can find parts is (anywhere) in the States!
That's and our Buck is not good right now, a $60 motor turns into $90 or more?

I think I figured it out, there IS another post about this and mentions the position of the control arm when reinstalling but the pics are all dead. Anyone have an idea here?

Make sure to plug in the motor first with it out and cycle the key to make sure its at it's starting point when you install it in the vehicle.

Did you do that?

Yup did that before installing just to make sure it worked in all cycles. In the How To section Rooster says to point the control arm a certain direction 9or 10, or else it'll go in reverse. I didn't quite think of that but I think it's he way the linkage or transmission works.
I'm gonna head out in an hour or so to take a closer look. I'll post some pictures will I'm at it too.
I assumed it was plug and play, the motor will only spin one direction so you'd think so.
