Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the wiper transmission crank arm. This is the arm that is responsible for actuating the wipers as well as getting them down into the parked position. It's the same for this Impala and quite a few other GM vehicles. You'll need a new wiper transmission crank arm from 1AAuto.com, 10mm and 13mm socket with a ratchet, T30 Torx bit or screwdriver, and a flat blade screwdriver.

Start off by prying off these caps on the end of either wiper arm, and then remove the 13mm nuts that hold those in place. Use a flat blade screwdriver, and just pry right here at the bottom of the wiper arm. Lift it up and off the stud. You can just set that aside and repeat the process on the other wiper arm. Then disconnect your washer hose from the wiper arm; do the same thing with this wiper arm. Now your arms are free.

Pull off the weatherstrip and unclip your washer hose. Just set those aside. You want to remove this clip, this clip, and right there, there should be a third clip. To remove these, you just pry up the center, pull it out, and then pry out the base. Just repeat the process on the other two. Then for this clip right here, you just want to twist it out with a flat blade screwdriver while lightly prying up with another screwdriver. Then you should be able to pull it up and out. Now lift this cowl panel up and set it aside. Lift up this panel and remove it.

Now remove this bolt, this bolt, and this bolt right here. Each of those are 10mm. Next, you want to remove this panel. To do that, you just need to pry up on this clip right here using a flat blade screwdriver. It'll pop out, and you can lift the panel up and off. Now you want to pry this arm free. Just tuck it to the side and then pull your transmission up until you can access the harness on the motor. Then just push the tab with a flat blade screwdriver and pull the harness free. Now you can pull your transmission up and out.

Remove the plastic cover on your transmission crank. Then turn your transmission crank so it's up against that post on the side there. Then just remove the T30 bolt in the center. Use a large flat blade screwdriver to pry the crank arm free. If you do have a two or three jaw puller you could do this without removing the whole transmission assembly from the vehicle. Then feed your transmission back down into place and reconnect your motor harness. Don't pay any attention to the fact that the crank arm is already installed. You actually want to install it after you've run and positioned the motor, which we kind of did a little bit out of order, but if you stay with the video here, it'll all come together.

Replace the three screws that hold the transmission in place. The crank arm has to go on in a specific position, so turn your key on and turn the wipers on to one of the delayed positions. Let the motor go around once or twice and stop, and then turn your key off without turning off the wipers. In this next clip, the assembly is out of the vehicle. I realize this might be confusing, but it was just a better way to be able to film this and really show the line up pole and how to put the arm on.

Your arm should be in the locked or running position. Put the line up tool down here there's a line up hole right here. While you're tightening up that Torx screw, you want to make sure that the arm is not moved, so hold that line up tool while you're tightening that bolt.

Then just turn your key on and let it pulse. Then turn the wipers off, and it should reset like this. Then reconnect your arm just push it down into place. Then push this panel back down into place, line up that clip, and push it back down in. Then replace your cowl panel. Do the same thing on this side and replace those clips. You want to replace the base first with the center still up, and then just push it down to lock it. Re-clip your wiper hose. Then put your weatherstrip back into place. Push this clip back down and replace the other clip. Push the wiper arms down onto the studs and replace those 13mm nuts. Once you've tightened those up, replace the washer hose and the cap. Do the same thing for the other wiper arm. Then you're all set.
