Review on 🔧 Dorman 76845 HVAC Knob Replacement: Simplify Control of your Heating and Cooling System by John Ghattamaraju

Didn't work on my machine. It will not sit flat. It hardly spins, so I can at least go from red to green areas (hot-cold). I just have to leave it there and then remove it and keep it handy. I compared it to my original pen and they look different (in size) to me. I'll go straight to Chevy to order it. My original is broken. The center hole is TOO SMALL on this model and won't fit my Camaro! Arghhhhhhh, not sure which car this fits. I need 2 for AC, heater etc. I have a 2 door hatchback.
