Typewriter noise in dash

[O2ShootTheJ]

Hey guys I noticed I have the infamous typewriter noise in my dash today. What did everyone figure that out to be?

It was an actuator for the A/C and the dealer replaced it under warranty but it came back shortly. I could never get it to stop. I hope someone knows a trick

Mine has done it since I bought the truck. And now the dual climate door has broken. The passenger side blows nothing but hot air

It's the Blend Door Actuator. I replaced two of the three and it stopped the cycling of the motor. The noticeable difference was the old motor shaft was out of position so when it closed the door the motor was not at the closed position and kept trying to apply an actuation signal to the motor constantly. Little did it know the door had hit it's end of travel.

The time involved to replace the drivers side and the upper passengers side will be about 5 hours and there is little to no room for your hands to get to the bolts to remove and replace.

You will need to remove the center dash cosmetic cover, radio, glove box, passenger air bag unit and lower covers under the steering wheel and under the center console. Good luck!

Thanks for the info Blowby! Will there be any further damage if I don't fix it? Sounds like more trouble than it's worth.

The actuator is already messed up so if it causes anymore damage it's going in the trash anyway. The only other thing that I might think of is possible heat from cycling but that could be a non issue. Nothing around it to ignite. The actuators are about $26 bucks so the time to do the job is the only thing that should hold you back.

I have he same problem but on a 2005 Chevy 1500. It even did it before lifting it and doesn't do it in the rain. I have taken the trim pieces off of the outside around the windshield and taken my a-pillar covers off as well with no luck finding it. I'm guessing this is the same problem?
