Review on Air Door Actuator - Replaces OEM 89018365, 604-106, 52402588 - Compatible with Chevrolet, Chevy, GMC 1994-2012 - Silverado 1500 and 2500, Tahoe, Sierra - HVAC Blend Control Actuator - Heater Blend Door by Paul Gravely

I had the recirculation actuator replaced and this part worked great for a week. Then it burned out and stopped working. I emailed the seller and he confirmed that I ordered the correct part for my 2004 Silverado. They quickly sent out a new batch. Installed a new one yesterday and it worked great again but this time it only lasted a few hours. The part has a lifetime warranty and the customer service is good, but I would not recommend this part. There's a reason it's over half the OEM price. I bought an ac delco drive and now my recirculation damper works as it should. Buy a quality part, replacing the actuator is labor intensive and you won't want to do it again. You get what you pay for.
