That is incredibly frustrating on a high end truck. Grrrrrr. Any idea on a service bulletin number or something like that to present when I go to the dealer?

2023 GMC AT4. It's hot outside, I get in the truck and start it. Auto climate control fan speed takes over and starts blowing full blast. Good. Here's where it gets weird. There's a half second pause in the radio and then the fan speed drops to a minimum. Move the auto climate temp knob, nothing happens. I have to go to manual climate control then back to auto or cycle the end call/mute button twice to get the fan speed back up. This happens twice on every start up. Very frustrating. Has anyone else had this issue? I thought maybe it was just my truck but I had a rental Suburban this week and it does the same thing. It's almost like the truck drops the fan speed to reduce the noise so the microphone can hear me better. But I initiate no action to need the microphone. Hopefully have time to go to the dealer in the next few weeks.

Succumbed to the condenser problem myself. 2015 with 72k miles. What brand is everyone DIY'ing this with? Murray from orielly, spectra from autozone, oem dealer and risk it failing again?

Recently flat towed a Jeep just shy of 6k loaded to Moab from Texas. Truck is 5.3 4x4 with 3.73 gears max tow package. 1,000 miles each way. In Texas on mostly flat ground going 65 the truck would rarely settle in 6th gear. Once we got into southwestern Co and the hills in southeastern Utah the fun began. I was routinely dropping to 4th and even 3rd to keep speed up. Ambient temps were fine so temps in the truck weren't an issue. It did open my eye on how dismal these things are at pulling on anything with a grade. Truck was able to do everything I asked it to do but I had expected more umpf to be honest. If I ever start towing regularly whether it be a camper/boat/trailer for jeep I'll be looking at the 6.2 or a 3/4 ton. I averaged about 12mpg staying around 65-68 the majority of the way.

18" Vrock Recoils

Any idea if this keypad would work for a 2015? I found the listing for a 2018.

Paid it off.

You took a full size on the Alpine Loop? Yikes. I like to take mine in the mountains but I'm not that brave! Ha.

Offroading Yankee Boy Basin in SW Colorado

Got back from a camping trip in SW Colorado. Took the truck up Yankee Boy Basin. 4Lo and HDC did a good job on the 10+ degree descents.

New wheels and tires! More pics/specs in my build thread!

Got my wheels and tires on. Very happy with the outcome! Bilstein 5100s on max setting. Vrock Recoil 18x9.5 (+15) 275/70/18 Nitto Ridge Grapplers The truck now sits at 38.75" in the front and 39.75" in the back. I just got the tires on this week so I don't have a real estimate to my mpg hit. There's a few more pics in my build thread.

The way you measured how tall your tires doesn't net true results because the weight of the vehicle shrinks the height. Ideally you should lift the tire off the ground for a true measurement otherwise the other way is to measure the radius from the center of the wheel to the top of the tire and double it.

I concur. Take it to local DT. Either they need to shift the tire around the wheel or match it up with a different tire. Way too much weight.
