#4517640 - 09/16/17 08:12 AM 01 Tahoe - fresh air blend door issue (?)

A problem started yesterday afternoon. As I left a gas station, I started to get a loud clicking noise from behind the glove box. It sounds a bit like a relay being tripped, about 1 click per second.

Turning the HVAC controls to recirculate eliminates the problem.

In doing a search, it sounds like a fresh air actuator is shot? I also heard the entire dash might have to be removed to replace it.

Any thoughts or ideas are appreciated. I am going into my mechanic on Monday, I am just trying to prepare myself for the worst.

Appreciate it.

You might be able to access it by removing the lower panel on the drivers side.

Its the teeth in the actuator. Depending on which one is bad the dash may have to be layed back to get to it. We get 6 hrs and replace all while its opened up. There is 1 that can be done without removing the dash.

Yes I was talking to a guy at NAPA just yesterday. They problem with new cars is they run pretty well but its all this kind of carp that kills cars and makes them unmaintainable in 8 to 12 years. So next time your looking for that shiny new ride pick the basic model without all the bells and whistles and you'll still be driving it in 20 years if you want to be.

Hopefully its just the blend door actuator. Pretty easy fix for DIY.

A cheap fix is to rotate the Gear instead of replacing.

If the part is reasonably priced , if I managed to get to the old one , I would replace it , not just turn the gear .

But it is your money , each to his / her own .

Best wishes , :-)

yeah, unfortunately, it isn't that one. All my HVAC works correctly, it is the actuator that must open/close the fresh air intake....

It is right behind the glove box. I can put my hand on the black box behind it, and feel the actuator trying to work.

Yup, those GM door actuators are always going out.

Would be nice if they made those gears out of metal , preferably ferrous metal .

Best wishes , :-)
