Review on 🔍 Enhanced SEO: Standard Motor Products RU-638 HVAC Blower Motor Resistor by Brian Cruz

Installed, lasted two days, relay closed and keeps HVAC fan speed up no matter what position fan switch is in. In fact, when the ignition key was turned to the ON position, the fan turned on immediately at high speed, even with the A/C off. I installed this part to fix an intermittent problem causing me to go back to the original factory part and I felt safer using the stock engine part, they've been around for a long time, I still remember the ignition parts of the Blue Streak series. years ago always top quality. Two days is pretty bad though, there's no excuse for that
