DIY: replacing electric motor / control module ?

Has anyone replaced their electric motor / power steering control module themselves ?

it looks like a 600-700 dollar repair from GM but they will not give me part #'s so i can fix it myself.
does anyone have any insight.
I AM OUT OF WARRENTY
basically the steering in idle and off idle goes immediately to the left. GM dealorship says replace motor and module.

any help is appreciated.

thanks,

Collision Catalog - 2006 - Pontiac - G6
Steering column, Steering column assembly, Motor assy, Motor assy - With electric steering - With electric steering $278.07 $164.84 $164.84 Delete From Cart


So i found the part i need and the Haynes manual is ordered as well. I also found out you need a tech II to reprogram it after the motor has been replaced. Also there are no open bullitens / recals for this problem. So now i wonder if it will still drive / steer after the motor is replaced or if it will have to be towed to the dealorship after the part is installed.

Any update? Did you get the part changed out? I'm about to go take the power steering motor out of my wife's car today. Did you have to get it reprogrammed or did it work fine? Please keep us updated!

i did swap out the whole motor. 3 plugs that are easy to remove and 2 bolts.
make sure when you replace the unit that there is 1 small orange colored rubber gasket inside where the gear set is. when i removed min it stayed in the steering colunm and wouldnt bolt up flush.

bolt the new unit attach the 3 plugs.

also you cant screw up where the plugs go because they all have special shapes.

Then once you start the car the wheel will go all the way to the left automatically !!!

I would suggest if you do not have access to a TECH II then you be close to the dealor as everytime you let go of the wheel the wheel will spin itself to the full lock position. Definately not safe to drive far.

it took my buddy 5 minutes to use the tech II to fix the car. and after that it was perfect. I was really suprised how easy it was to tune the computer after the new unit was in. I went with a unit from a wrecked car and it has fixed my issue !!

overall i paid 175 for the unit and computer tune...but i have a good connection with my mechanic he didnt want to charge me that i just gave it to him.

Thanks. I sent it in to get rebuilt. I just don't know how I'm going to program it since I don't have a tech II or know where to get one.

Hey, what do you guys mean by "Collision Catalog" or sending it in for a rebuild? I have the same damn problem and RockAuto shows my car as having a pump! I understood it as having electric, but I can't find the part. How did you do it, oh great ones?

So, I got the assist module back from the company that was supposed to rebuild it and they sent it back saying that they can't locate the parts to rebuild it. So i called the dealer and they want $495 for the assist module by itself or $700 for the whole steering column with the module and everything. So yesterday I called up to this little place in Rancho Cordova, CA called Recycle Road. They have every junkyard possible! The guy there told me he has an entire column for $240 with a 1yr warranty! Sweet, I headed up there yesterday and picked it up, but it was from a Malibu. No problem, they are the same part number, but it has an ugly brown malibu steering wheel and won't look anywhere in place in a black interior G6. So I figure that i'll just take the assist module off the new one and put it on the old column with the old motor and voila! Not so fast! I bolted (actually two little inverted torx screws that connect the motor to the "brain"/assist module) it together and started the car thinking, That Was Easy (kinda like the staples commercial), and low and behold the steering wheel shimmies all over the place just like it did before. so i turned it off and tried again. It still shook but i was like whatever, if it has the power steering i'll live with it. Then the infamous BING! No more power steering!!!!!!!!! So i'm now going to replace the factory column with the "new" one and see what happens. Now I am trying to figure out how to remove the air bag so i can take the G6 wheel off and put it on the malibu column.



And as to the guy that ordered the part and was waiting for his Haynes manual, How did that go for you? I came to find out that they don't make a Haynes manual for an '06 G6!!! It's not really neccessary anyway since it is just two bolts under the dash and disconnect the column from the shaft and voila!

FIXED!!!!!!!!!!! I just finished taking it for a test drive and it works great!!! no need to run the Tech II or take it to the dealer for any re-programming! I ended up not having to take the air bag and steering wheel apart after all. I gazed at it for a minute and i realized that i could grab the steering wheel and pull away from the motor and the shaft that the wheel is mounted to slid off of the motor shaft. I then swapped the "new" motor and shaft off of the Malibu column and it slipped right on. (This is all after you take the whole column out of the vehicle and have disconnected the clips for the wiring harnesses for the Air Bag, Wipers, and Headlight/Turn Signals). I then bolted it all back together and BAM! I was done.

For those of you that want to do it yourself it is pretty easy. Once you take all of the plastics from the lower dash off, take the metal shield that is below the steering column, like where your knees would hit, off. It is just four bolts/screws. Then remove the wiring clips off of the steering wheels for the air bag, wipers, and turn signals. There are also three clips on the Power Assist Module that is connected to the motor. don't forget to remove them! Then there are two bolts mounted vertically, one on either side of the column to the dash. Remove them. Then there is a bolt that goes through a clamp on the steering shaft after it comes out of the steering motor and before the u-joint for the shaft that goes through the firewall. This bolt is SUPER TIGHT! If it comes out while you are driving, no steering for you and CRASH!!! After you remove the bolt, tap the clamp a few times with a hammer or something to jostle it. then you can slide the clamp and shaft that goes through the firewall off the motor shaft. When you are all done with that, you should be able to see-saw the column up and down. There is one last bolt that runs through the top of the motor into a nut that is held into a bracket. Once you get the bolt out it is free. Set the old one next to the new one on a table or ground or whatever. You then can slide the steering wheel shaft off and switch it onto the one you just bought at the junkyard for $200-$250 and put the "new" shaft with your stock wheel in the car. Just put the bolts back in reverse order and voila! Don't forget to put all of your clips back in! If you don't put the wires back on the power assist module the car won't start and then your heart will fall thinking that it is because the new column and some wiring crap. Don't ask me how i know

Check your facts there chief.... they do make a haynes manual look on amazon.com !

It still doesnt help though as they just write " most cars have a electric assit motor."

You do need a tech II to reprogram the new unit. And all you need to do is replace the motor itself which is held in by 2 bolts. its a easy install. you dont need to replace the entire steering column.

Wow! If you could calm down on the attacking and racial comments that would be great. I was just asking how it went for you and that I couldn't find one. Secondly, I did just take the module and install it on my original column before I took the whole column apart and guess what! It didn't work. If you were to actually read the whole post that you replied to, you would find that in my case I had to replace the whole column. My car didn't need a re-programming and is functioning perfectly. I guess every case is different! All I was trying to do was help everybody else out that doesn't feel like going to the stealership and shelling out $700-$1000 for something that can be done in a couple hours and only a couple hundred bucks.

Well nice job to the both of you

I have the electric steering also (05) And this didnt happen to me so im just throwing it out there but the tech is to re-calibrate it?
Is that why it kept pulling to the left, it thought that was the center?

Hey, thanks to everyone. I ended up just letting the dealership do it. It became clear to me that it was hard to find that electric assist motor. I also placed an ad on craigslist asking for someone with a tech ii to reprogram it for me. No responses there either. $570 and our car would work right again. This car is a daily driver so we couldn't afford to be without it for very long. The dealership said it wasn't the motor but some kind of sensor. I don't know if I believe them, so we will be watching it closely. They did say they would have to take the steering column apart.

Thanks again.

The on going problem with EPS is the torque sensor, no field repair, column needs to be replaced.

Red face

Mine started doing it after replacing plug wire, o2 sensors and plugs. The only thing I touched was the alternator, the above of course, and disconnected the battery the third time (taken apart 5x) when the problem started. Only under HARD acceleration and when the vehicle is hot, it will flash all lights on the dash and then I lose power steering until I let off the throttle. Alternator has been tested in the car and out of the car. Works fine.

What the hell. I had GM replace the column because I received a letter, but not sure what was included in that replacement. The car rides much better but problem still exist. I thought I read that someone had a tensioner pulley causing the problem.

Any thoughts??? Please!!!

Daughter's 06 G6 with 16,000 miles had intermittant and unexpected failure of power steering for two weeks, almost crashed twice. Took it to the dealer Friday Jan 7 and got a $825 repair estimate to replace electric power steering assist motor. Same problem as recalled 05 G6 in service bulletin above, but not covered under warranty for 06. I filed complaint with NHTSA (888/327-4236). Contacted GM to work through this obvious warranty problem. As of Jan 12 I have had nothing but the runaround from GM/Pontiac. Spoke with three different folks at GM, including District Specialist yesterday (Jan 11), and have heard nothing back but "We will call you back." I have not received a single option from GM as how to proceed with this. Dealer did offer to insall new motor for $ 200 labor only bill. I will give him credit for trying. THIS IS A SAFETY ISSUE. If others are experiencing this problem, you must let NHTSA and GM know, in no uncertain terms, that this is a real safety issue.
