I have a 02 silverado and the a/c stays on the outside air function instead of going to recirc mode. I know that when you shut off the air it goes back to the outside air duct but it is staying on that setting all the time causing stinky air to come in. Also when the air is on with that setting the fan dosnt blow has hard as in recirc mode this is my biggest complaint......Does anyone know where I can look first to fix the problem....I have changed the cabin filters and the light comes on when i hit the recirc button...anyone have any suggestions..thank you :thumbs:

I know on my '03, it depends on which vent you're using. If you turn the vent dial to defrost or anywhere to the right of the 12 o'clock position, the system automatically opens the refresh vent. If you go left of the position, you have the option of turning the turning the vent button off or on.

My '02 Sierra does the same thing, I am not sure why the AC compressor comes on recirc. mode, but probably to keep the windows from fogging up. Doesn't make much since when you have 30% humidity outside.

On my '05, recirc mode will only work with the vent control knob left-of-center. Plus, even then, it only recirculates some of the air. It still draws in some percentage of "fresh" air from the cowl. And that means there's no escaping those gross polluters' stinky exhaust.

 

It's a shame that GM can't let the driver decide if he/she wants to recirculate. But I think it's because they listen to their stupidest customers, and ignore the smart ones. The stupid customer will complain that their windows fogged up, because they're clueless about humidity, and clueless about the need to draw in fresh (dry) air during cold weather. So GM makes it impossible to run the defroster in recirculate mode. Stupid customers therefore can't screw it up.

 

But thinking customers who own GM products lose in the trade off. After a while, they go buy a honda, or a toyota, where the recirculate decision is left to the (intelligent) driver, regardless of which vents have been selected.

Sounds like maybe your actuator on the recirc door is shot, either that or the heater/ac controls are busted.

 

Could replace the actuator and see what happens...

"Thinking" people will always be in the minority, and therefore not appeased by a large corporation such as General Motors. I don't blame GM--it's just what's profitable. Un-Thinking people outnumber the rest of us by

"who-knows-what : 1"

The large corporation stereotype is well demonstrated by General Motors, but most of the Japanese manufacturers don't fit that stereotype. That's why in a lowly Honda Civic, when you change the vent mode to defrost, the a/c button lights up and you can press it and turn the compressor OFF. That's why in that same vehicle you can press the recirculate button during any vent mode and the system will recirculate. Honda realizes there's a way to appease both the stupid, and the thinking, driver.

 

GM doesn't bother.

 

I worked at Ford for a few years, in Dearborn, MI. I had an idea for a driver's computer that I prototyped on my own time, and used, and it worked! But in its initial incarnation, it was pretty complicated. I demonstrated it to a product planner at Ford, we went for a test drive, yada yada. One of the things he said to me: "It's too complicated. We have suppliers come to us with a 13 function trip computer and we have to have them dumb it down to 4 functions--people just can't handle the complexity!"

 

Doesn't that just tell all. We could have 9 more functions on our trip computers, for the same price, if it weren't for all those stupid people who won't bother to read instructions. I'm pissed! They're stealing 9 functions from me!

      Joke Thread

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
