Does anyone know if I replace the manual tri-zone climate control panel with the automatic control panel? Thanks.

 

I don't think so. Be happy that there is something you have control over in your GM product.

 

I suppose anything is possible. Is it feasible? - Probably not. This is something that you just have to buy as an option the first time around. There are simply too many wires and sensors involved to make this an easy swap. In fact, you may not even have some of the wires available. It would not be a simple "plug and play" install.

Like I said, anything can technically be done with enough time and money, but this is not something easily done for the DIY'er, and at a low/reasonable cost. Someone can correct me if I'm wrong, but I would suggest putting your money towards something else.

 

This has been discussed at length. Short answer is No.

After having auto HVAC, I will never again buy anything without it. Love it.
