Not a mechanic but just went thru this with my daughter's Trailblazer. Probably an actuator. Hers was blowing cold on the floor and the windshield but not thru the conventional A/C vents. It was about a $150 fix. You can try unhooking the battery and see if it resets itself but it didn't work on hers.

Is it the actuator close to the floor
the one I think it is is the one that turns when I raise and lower the temperature I want to make sure because it looks like it's fun to take it out

It's the lowest one close to the center console on the driver side of the dash. Keep in mind if your vehicle has automatic climate control, you will have to get the actuators recalibrated for the temp controls to work accurately.

No such thing. OP, order the part I linked. Make sure the part is installed completely BEFORE you operate the system. That will fix your problem.

No such thing as recalibrating? While it will more than likely work without the calibrating on a manual a/c system it is recommended on systems with automatic climate control to prevent premature actuator failures. Vehicles with manual a/c does not require recalibration. Not my vehicle, I don't care how it's repaired. OP asked for advise...I'm giving him mines on what has worked for us.

No going to get into a pissing match with you. I posted a link of the part that the OP needs. I absolutely does NOT need anything but installed. He must not plug it in to "check it". It will throw off the position of the actuator. Vehicle battery should be disconnected, and the actuator installed properly. There is a line on the part marking the correct position. Install part, rehook battery and enjoy equal air temp on both sides.

My parents have a newer Tahoe that had the driver's side vent blowing hot air. He researched and found that pulling a certain fuse and letting it sit and then going through a certain start up got it working perfectly. Blowing cold like normal now. He found the video how-to on Youtube. He said you could hear the vents re-cycling upon start up.

Just to make sure we are talking about the same part. When this part fails, it will allow one side to blow cold and the other warm.

No. No pissing match at all. I wasn't aware of another method such as yours. We have a GM Tech2 at the shop that we use to recalibrate the actuators same end results
