was a lot easier to install than the video looked like. Solved a lot of a/c problems directing the air flow

Poor quality part failed from the start.

Chinese part failed to function from the start. I had to have my local garage repair the problem. They installed a new part from their supplier and now I have a functioning blend door actuator.

Actuator

Fit exactly like OEM. Received in 2 to 3 days, even during Christmas season! Only thing I would improve is to keep the moving white part as metal. But the plastic may be engineered to be be just as durable...? It fixed the issue and I would buy it from 1A again!

Temperature Blend

This unit worked great and I have been using it awhile now. The old unit died while on a trip back home, got this unit from 1A Auto and been work nice ever since. Fit my 2001 Chevy Tahoe living in Phoenix it stays on Cold a lot. But these cool mornings now I can see how it really works.
