Blend Door Actuator?

Sysrq4651 · 2019-08-06T13:54:59+00:00

Recently my front vents stopped working on my vehicle. I've tried to re-calibrate by taking out the fuse, waiting a couple minutes, putting the fuse back in, turning the car to run, letting it go through its motions, but that didn't work. The air blows cold, but it is only coming out at the feet, side vents and defrost. How do I replace the vent actuators?

No problem. We are very familiar to the "When I have time" situation.
