Blend Door Actuator

[monstermarlin]

I changed my blend door actuator today, on my silverado 2500hd. I know it is a common problem for them to go bad. I held off for a while because of the price involved. I was quoted 1,000 from the dealer to fix. I bought one on amazon for 99.00 (dorman) and installed and re-callibrated in less than 20 min. Blowing cold air on both sides of truck now. Thought I would share as I know many will need to change theirs too.
