Worked exactly as expected on my 1995 K1500. The design of this particular one varied slightly from the original, 29 year old fan speed controller. This one had the resistors spaced just a little more and all seemed to be less easily bent/more durable.Just as easy (or hard) to install as the OEM part. 10/10, would recommend.

It fixed the the problem. Before my blower only worked on high now each low med high works. The part is easy to locate but it's a bit harder to unscrew then you'd think. It took a bit longer to take out the old part then I thought but simple non the less.

Installed this on my 1998 Chevy Tahoe. Worked like a champ to give me back all my speeds! When these go, you will only have off and high. All of the speeds in between are gone. Very common thing to go. Installation wasn't horrible (I've replaced some dandies of these in other gm cars). Great price on this also compared to all of the local parts stores.

Direct fit and much cheaper than the parts store. Matches the OEM part and hasn't failed. I would recommend it. I bought it for my 99 Tahoe.

Other than an awkward job replacing the original, the unit itself worked as advertised and allowed me to drive without scraping the windshield the whole trip. Great to have heat at -35º

Resistor works great. Way less money than GM replacement. Not enough room to install as is. Had to bend resistors to make it fit. Original was the same way.
