Killed a hub. Worst i have ever let one get, but had to get it home on it. After nearly 3 years though....it is bound to happen
Checked continuity on the climate control last night and it looks like the actual control unit is toast. I ordered a remanned one from Ebay last night, so that should fix my dash vents not working...2 new actuators and it's the control head, go figure.
Today I'm going to remove the rear sway bar.
Dealing with the same thing with my 4wd. Replaced 2 actuators and still need the control head. I swapped in a known good one from my 2wd trailblazer and I still have a little issue it seems like. When I put it on defrost, it blows out of the vents, too. On vents, it doesn't seem like it's blowing as hard as it should be. Like there's a door not sealing or something. Can't compare it to how the 2wd ac blows because the 2wd just got a valve job and new valve in the head and still needs the head put back on.
Ugh.
Manual with the sliders. I've got some sort of intermittent issue with the temp control. If I reset the system, it works fine for a bit. Then it won't change when I go from cool to heat or vice versa unless I take the slider and go up and down, from top to bottom, about 10 or 20 times and it will usually change to the desired temp.Is yours auto climate control or manual with the sliders for temp?

That's correctFound some interesting bits and now will likely watch for it...
LS1--"AC compressors aren't designed to be spinning at the higher revolutions so it disengages over 4k rpms and also at a certain percentage throttle opening. Its more for longevity of the compressor than performance. Just about all cars will cut the AC in this manner. Even my '93 GMC pickup does the same."
The electricity to the AC clutch is cut off, disengaging the AC clutch. It doesn't shut off because it's trying to free up power for you. It shuts off to save the a/c compressor from damage.
Makes sense.
installing my new HU, Pioneer AVH-X2800BS. Soldered the harnesses together last night, taped everything up and it's ready to go.
