1) Your compressor is bone dry? The item driven by the belt at the front of the engine? Perhaps you mean the drier/receiver, up high by the passenger side of the firewall? If the drier/receiver is cold, and dry, that just means there's little humidity in the air. If that's true, then there should be little condensation on the evaporator, the cold part of the system that cabin air blows over and makes the cabin cold. That condensation gets collected and drips on the ground by a little rubber tube near the drier/receiver.

Could you explain a little more clearly what's dry and what you think should be wet?

2) I assume you mean the HVAC blower and not the engine fan. There is a failure mode of the speed module that could cause it to come on, and potentially drain your battery. Do you have the analog controls or the digital?

Thanks for the report. Nice to know about the software update as well, so it's not a surprise next time. It's odd the things that GM is fixing nowadays.

...there is no liquid coming out from the bottom of the vehicle.:thx

Ahhhh, that's going to end up draining all over the passenger's feet. Fiddle with the drain hose on the firewall and poke a wire in the end if you have to. Be careful as a quart of smelly water might suddenly show up.

I was also told by the dealer, that the condensor, will not produce liquid unless it is very hot out, ...

They lie. The AC runs to dehumidify the air when it's as chilly as 40F. It should drip all the time. Your drain is clogged. I have no doubt.

You risk it backing up, and dripping moldy water on the passenger's footwell. It's trivial really. I posted how earlier. Fiddle it, wiggle the rubber nozzle, poke at it with a stick, pull it out of its snap-in fitting if you have to. Clear the gunk/bird's nest/dead spiders out of the nozzle and plug it back in.

Just go out there and do it. It's not hard. It would take less time to do than to keep writing questions about it. :crackup: :woohoo:

If nothing drains out, then it hasn't been humid enough to collect any water off the evaporator.

Let's separate the two items. The fan blower is for airflow, and the AC compressor in the engine compartment is to get the refrigerant to get cold. The AC compressor can work independently of having airflow.

Did you recently change or disconnect your battery, or have to jump start it?

Do you have the digital or manual controls?

What do you mean the driver's side controls aren't working? What control are you touching and what do you expect it to do?

There are a couple of fuses to check, depending on your answers, and a possible DIY repair. How handy are you? Do you have a meter and know how to use it if necessary?

...the driver side controls which works the windows and the locks does work ...

It DOES or DOES NOT work? Please be careful and precise when you're trying to get troubleshooting assistance.

Your door controls have nothing to do with your ventilation blower. They may be flexed and broken wires inthe door edge near the hinges.

Are you going to do the work yourself, or do you have a mechanic?

Your blower problem is possibly a simple resistor pack as long as you're sure it isn't fuses.

...Is there a connection between the battery being disconnected and my A/C not working correctly? ...

Yes. A battery swap or total discharge will triggegr a recalibration of the HVAC system electrical actuators when the ignition first gets turned on. Search for "temp actuator" or "mode actuator" and do some reading. You might try a system reset by pulling a fuse (documented in those threads you will find), but due to a GM design error, many of the actuators are simply too weak to survive the recalibration.
