'99 GMC SIERRA BLEND DOOR ACTUATOR FREE EASY FIX

This video was created with the idea or helping fellow YouTubers on fixing this actuator's most common problem. A lot of older GMC and Chevy trucks have this same actuator failure due to a cracked plastic gear. This plastic gear does not have the electric connectors that exist in other models, facilitating the repair by simply rotating the gear. This failure is noticed when climate control fails to respond to the hot and cold selector. The air coming out of the vents is either stuck in hot or cold. I hope this video helps the DIY out there as well as some other videos have helped me with my projects.
