Most Liked Positive Review
fits great
if you have a factory multi spline window motor. you will need to buy the motor that fits this as well. it wasnt a big deal just couldnt finish this project in 1 day due to my local store was closed on sunday
Most Liked Negative Review
Not a direct replacement. Read other reviews
I made the mistake of not reading other reviews before buying but I got my door ripped apart and pulled the OEM motor from my regulator and as others said they changed the splines at some point. So my factory motor that works fine was unusable. Also my truck had 2 bolts and 2 nuts to mount where this is 4 bolts. Had to return and spend 30$ more to the one with the motor. If I knew all this I would have just ordered from RockAuto but paid more for the "convenience"

New design does not work with previous unit's motors!
Verified Buyer -
Beware, vender changed from previous design of regulator where the previous motor now does not fit the new model's mounting location. They offset one of the mounting holes that precludes the motor to sitting flush with the bracket. I had to return this regulator and pay $50 more dollars for the complete regulator w/motor.
I would not buy this again.
The vendor didn't say that the new regulator wouldn't fit the sprocket on the original motor. Couldn't adapt. Waste of money.
Bring your old electric motor with you when you pick up part
I wish I had read the reviews on this window regulator. Like two others, I needed to return it, due to my good existing motor not fitting this regulator replacement. Advanced was Great about the return!
Bottom Line No, I would not recommend to a friend
Perfect Fit. Would recommend highly
