An Adequate Replacement
This is the second time I have ordered a blower motor resistor for my 2008 Mercury Mariner. The part arrived very quickly, even sooner than estimated. The part was a perfect fit. The "how-to" video on the site, along with others I found on the internet were very helpful in replacing the part. I just hope that this resistor lasts longer than the last one I installed.

Heater/AC fan speed control restored
When I was left only with the highest fan speed on my 2009 Ford Escape I googled the problem and was surprised this was a common problem. Further search yielded a great instructional vid along with good price and shipping cost from 1A Auto. I received the item in couple of days with regular mail. Note: if you have a problem with uncoupling the electrical connector, remove the blower motor resistor first, then uncouple.

great find
After about two years of putting up with one speed (high) on my fan in my F150 truck, I finally found out it was the resistor for the fan. I ordered this for about $25.00 and in 25 minutes I had it installed. Ford Motor Co.wanted $100.00 to look for the problem.

Exactly what I needed.
Exelent product. Shipping was faster than expected. Did exactly what I hoped it would do. Before the heat and a/c would only blow out when on the highest setting now it works great on all the settings. I would definitely recommend this product if you are having the same problem as I was.

No issues
The part came quickly, was easy to install, and works as expected. I can’t comment on durability yet because I’ve only had it for 3 weeks, but so far so good.
