Assuming the coolant level is full, this problem could be a plugged heater core. You can remove the hoses from the core at the firewall and run a garden hose on full blast into one hose, then into the other hose. look for debre to come out, then the water to get clear.
If the engine is the 3400 v6, you could also have a headgasket problem. A blown headgasket will pump compression into the cooling system causing air pockets. Air pockets cause a no heat condtion. The rear head is common for this. Removing the spark plugs and looking for them to be corroded from burning coolant is one way to check for this.

I own a 2001 Oldsmobile Alero 3.4L and I am having a very strange A/C problem. I recharged the A/C and now the compressor turns on but there is no cold air out of any of the vents in any position (front, feet, defrost, etc.) The Heater works great though. Checked all fuses. I'm just absolutely stumped on this 1. Any help would be greatly appreciated
