What if that has power? It's looking like I might have to take it in. What do you think?

Does it have power? You need power to it for a signal to be sent to the PCM to energize the relay.

You may have a bad switch.

I don't know. Soon as I plug in the AcPro, it goes to red. Instructions say something is wrong if it goes to red. See Mechanic.

That means either the compressor is not working or the expansion valve/orifice tube needs to be replaced.

Air Conditioning problem
2001 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic

I have the dual climate controls in mycar. The passenger side blows very cold, the driver side is much warmer. I added refridgerant and it just made the passenger side colder. Why is the driver side so much warmer and how do I fix it?
Thanks in advance for the help.

One thing I would check to make sure of is the the temp slider is functioning see if it changes from hot to cold normally or if it seems to be stuck at one point.
If not that then id try to see if there is a air leak in the vents.

My heater blows warm air on the passenger side vents, floor and defrost but it takes awhile. It blows cold air on the drivers side vent and floor. My question is what's causing this and how can I fix it.

My heater and ac do not work on dial settings 1-4, but on 5 it works. In addition, when I change the dial the headlights turn off.

If you are talking about fan motor, then most likely the fan switch is bad, replace it.
