Blower Motor Resistor
The fan works on all speeds again and wasnt to hard to put in as long as you have the right tools.

the end of the resister bent and the solder broke off
This damage could of happen in shipping. I was able to solder the end of the resister back on. I had the under dash apart so I could not wait to have a new one shipped so I was able to repair the part. So far the Blower Motor fan speeds work fine at this time. I value the videos that 1AAuto has and it is of great help to repair my vehicle.

second resistor worked
The first resistor came quickly and blew fuses when the fan was turned to high. The second resistor came and has worked as is it supposed to. Customer service was good. Delivery time each time was quick. Just wish the first resistor would have worked.

Item was exactly what I needed. Contacted customer service with few questions. I got a quick respond. The website is also easy to navigate. Prices are very reasonable also compared to the big name part stores.

Excellent Replacement Part
Did the replacement and it works perfectly. Be advised though that trying to remove this part, which is located right against the firewall, behind the blower motor is very difficult. I eventually had to go to a Goodyear auto place where a much younger, shorter and more flexible fellow was able to get it out. One of the screws is almost completely hidden by the part itself and right against the firewall and you will have a tough time getting at it but it is possible. VERY awkward to get at the screws to take it out!

hard to install
I enjoyed the video on installing the part and realize all cars have little differences but this part is hard to extract on my model. I was able to disconnect the wires and plug in this new part with no success in blower function. Im still trouble shooting the problem . I might need to order a blower motor from you.

They sent the correct part , it snapped right in. Sales people were very helpful . I will buy from you guys again . Recommend 1Aauto to my friends.

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
So if you need a motor in your car will this fix it?
Ashley W August 7, 2017
No this will fix the resistor
Aaron S August 8, 2017
No. When this resistor fails it causes the motor to work on high speed only. If the motor doesnt work at all then check the fuse at your fuse panel or check for voltage at motor plug with volt meter. If the fuse is good and or you have 12 volts at the motor plug then motor is probably no good and needs to be replaced.
Jeff G August 8, 2017
Ive changed the resistor, and the motor but it did not help me.
Frank L August 8, 2017
Depending on the reason for fault, this will replace the resistor. There is a separate component for the blower motor but in some cases the motor will not operate on certain speeds because of this resistor.
Alex P August 8, 2017
Ok, so if your blower motor only works on one or two of the motor speeds or if it went out gradually then its probably the resistor. Seldom does the motor go out. Its a fairly easy fix, but watch the video on utube it really helps.
