An Adequate Replacement
Terence
June 26, 2017
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.

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.

The part ordered was due to you tell me (googeld) what was wrong with my truck.. I am far from being a mechanic but I ordered the part from you.. it came real quick. The link sent with it was great and because of that it took only a few minutes to install the part and correct the problem. The link showed how to install the part
Great service

Thought I was going to have to replace my blower motor but with help from 1aauto they directed me to the real problem. Fan worked on high speed and only needed a new resistor to bring back lower speeds. Their video showed me how to replace it with ease and save a trip to a repair shop and save me a bunch of money. Thanks
Works Perfectly!

The fan on my 2010 Ford F-150 XLT formerly worked only on level 4. This part fit my truck perfectly and my fan now works great. The 1A Auto YouTube video also helped greatly. Ive had this part installed for 2 weeks no, and no issues. I highly recommend!
Came on time, saved about 1/4 the dealer cost

Installed on a 2011 Ford escape. It has been working well for the month that it has been in use.
Worked, but not fully

The resistor did help. However, it didn't completely fix the issue. I previously only had settings 1 and 4 on my switch. I now have 1,2, and 4, but there isn't any difference between 2 and 3. For the price, I am happy with this, but I wish it would have fixed all 4 settings.
Quick and easy

looked just like you picture. Had to go online to find where this part went. YouTube just said behind the glove box. NOPE! i ended up using a mirror and looking for 4 wires. It was on the right side of the console .Up high and out of easy reach. Took me 2 days to replace part. I now have my low speed fan working again. I would hate to have taken this to the dealer to replace .

Replaced the old & busted resistor in my 2012 Ford Fiesta, & now for the first time in a long while my vent fan works on all speeds. I likely saved over $200 in service garage fees.

My guess is that you have changed that actuator yet no luck so next I would have the blower motor tested to see if it has gone bad.

This resistor controls the higher speeds. If only 1 speed is working it may need to be replaced. I have replaced mine in a 2010 Ford Escape twice. The videos on line were informative. Tight quarters but pretty easy to replace and I am not a mechanic by any means. Good luck!

I took the resistor out of my F150 and there is no way the replacement part will fit. Ford part number is 9L34-19E624-AC. Google the Forn part number and compare?

The resistor (part number 9L34-19E624-AC) you removed from your F150 is for an AUTOMATIC temperature control system. The replacement part number you ordered was for a MANUAL temperature control system and why it doesn't fit.
