    Perfect fit and function

    AutoZone has this part labeled as a "lift motor", but more specifically it's a window regulator. The electric motor isn't actually included in this part, but my motor was fine (and bolted right up to this part), it was the cable that lifts and lowers the window that failed on my Avalanche. Apparently just the cable itself isn't available as a replacement part, but rather this entire assembly must be purchased (but $67 isn't too bad to get a window working again).
    I was a little surprised that my local AutoZone had this part on the shelf, but they did!
    I'm not a mechanic (retired police officer), but can usually figure out most mechanical repairs on my vehicles when the need arises. Everything from brakes to coil-packs to exhaust work, I've tackled. While this part wasn't too technical of a fix, I still have to say how pleased I was at how smooth the replacement went! That's mainly because this Dorman part sold at AutoZone is a direct-replacement for my window regulator, and now my window raises and lowers just as smoothly and quietly as when new! (It had been making some strange grinding for a few weeks before total failure.)

    Pros: Cost effective, direct-fit

    Cons: None
