Product Details

The Standard Motor Products RU521 is a direct-fit HVAC blower motor resistor designed to restore proper fan speed control in your vehicle's heating and air conditioning system. This precision-engineered component controls the electrical current flowing from the fan switch to the blower motor, allowing you to adjust airflow at multiple speed settings for optimal cabin comfort.

Key Features:

  • Controls electrical current to regulate blower motor fan speeds
  • Engineered to meet or exceed OEM specifications for reliable performance
  • Manufactured in an IATF 16949-certified facility for quality assurance
  • Features tin-plated steel terminals for maximum contact and corrosion resistance
  • Constructed with high-quality ceramics and copper electrical connectors
  • Designed for direct-fit replacement and maintenance-free operation
  • Rigorously tested for draw, resistance, and RPM performance

A failed blower motor resistor can leave you without heat, air conditioning, or proper defrost function. Common symptoms include the blower only working on high speed, fan speeds that won't change, or no airflow from the vents. The RU521 provides a dependable OE-quality solution to restore full HVAC functionality. UPC: 707390746050.

I was out of town, so I didn't have much time before my Dad's birthday to send something.. Unbelievably fast shipping! A++ The K&N air filter was the cheapest in the web!

SMOOTH TRANSACTION- you wont find all the items you need all in the same place elsewhere

Fast shipping and best price I found anywhere.

They have the best prices and fast shipping too.

Ordered Thursday, shipped Monday... guess all in all we can't be disappointed. At least they had them in stock.

** Update 4/18/2012<br>Everything arrived in several different shipments. I did experience a problem with some FelPro Headbolts that I had ordered. I ordered two and only received one, but after a short phone call with Paul from shipping, the problem was fixed and my second set of bolts were shipped.<br><br>They had the cheapest price that I could find on several products. I did not like the order confirmations on there website as I had to copy and paste to search for my tracking number. I am supposed to receive my order today and I am scared because the two weights do not match up. Autoplicity says 37.7 pounds and fedex says 3.8 pounds. Maybe there is more than one tracking number and I just do not know.
