My 2012 Ford Fiesta suddenly had this horrible burning plastic smell and then the fan speeds no longer worked on 1, 2, or 3 , but 4 worked fine. A quick google search told me this part would fix my problems and they were right! The part came in 2 days, then we switched it out and my fan speeds all work again! Saved me so much money over taking it in for service!

These resistors are a pain, because they seem to go often. Easy to replace. Mine is just behind to glove box. The original lasted about 5-6 years, and then I purchased a generic brand version. That non-name brand version only lasted about a year, so I came back to this Motorcraft version. I hope to get another 5-6 years on this. You know you need this if your A/C will only run on the highest speed or you loose any of the slower speeds. Worked in my Ford F150 2010.

Works as intended, fixes the blower fan problem instantly. Good part, too bad I needed it in the first place. Only installed recently so can't review for longevity yet.

To Ford Motor Company - I've had this problem on 3 different model Ford vehicles over the years, all failed due to the PCB seal failing and internal corrosion. Obviously this is a design issue, there are hundreds if not thousands of similar reports on car forums online. Find a better way to manufacture these components. Really with modern solid state electronics this is a simple part that should never fail.
Also, while I do appreciate that it is somewhat accessible for DIY repair, it's still in a very awkward location behind the glove compart facing upwards. It would make more sense to put the connection facing out. But then, if it were properly sealed it wouldn't need servicing in the first place.

The fan control on our 2012 F-150 XLT 4 door would not work on the lowest setting. Did a little research on YouTube and decided to take a chance. The YH-1715 was the exact match for the resistor I removed from our vehicle. The space behind the glove compartment is rather small, and removing the two screws is a bit awkward. I used an 8mm wrench, as the socket didn't seem to want to hold the screw head. Once that is done, the old one is easily accessed, but there is a retainer on the plug so it is a bit hard to un-plug. The new one was an exact fit, and instantly corrected the problem. 10 minutes on YouTube, 10 minutes of work and a $20 dollar part was much better than $150+ for my local Ford dealer to do it. Forgot to mention that delivery was ridiculously fast. If only everything else in life were this simple!

Fixed my 2009 Ford Escape heater/AC fan speed control. The 1 & 2 fan speeds quit working, 3 & 4 would still work. I went on line and found this was the fix. Not too hard to install. Remove the three screws below the glove box hinge to remove the glove box. Looking up to the top of the blower housing you will see an electrical plug. The plug is connected to this motor resistor. Remove the plug, you may need to pry it up to get it loose. Two 8mm screws hold the motor resistor in place. The flat section of the motor resistor is down in the blower box. Remove the old resistor. Notice the hole pattern on the mounting flange. You may need to drill out a few of the holes (3/16" drill) to match the open holes on your old resistor. This is really easy. Be careful to remove the the thin foam gasket before you drill out the hole. Install the new unit with its gasket. Connect the plug. Your fan speed control should now work. You can find a really good video on line.
