1. Are the HVAC fans working (blowing air) when heat is called for?
2. Is the engine coolant up to temperature?
Sounds like it may be the valve that lets heated coolant flow into the heater core. If so, that could be the valve itself, or the signal that controls it.

I HAVE A 99 INFINITY QX4 AND WHEN I TURN ON MY AC/HEAT IT COMES ON BUT DOESN'T BLOW. I FIND THAT WHEN I DRIVE AT A CONSTANT SPEED (I.E. ON THE HIGHWAY) IT BLOWS OUT AIR/HEAT BUT I HAVE NO CONTROL OVER HOW HARD IT BLOWS OUT, ONLY CONTROL OVER TEMPERATURE... WHAT COULD SOME POSSIBLE ISSUES BE?

The blower fan isn't working. Check the fuse first. If it's not that, then see if the blower is getting voltage when it's on (voltage varies with blower speed). If the voltage is present at the blower connector, then the blower fan is probably bad. If it's not then it could be the control itself (manual or auto if there's climate control).
What your feeling now is just the air that flows through when your moving forward.

A/C not work. Took several visits to dealership. Was under warranty. Leaks not detected with dye. Evaporator cord replaced. Still no A/C. Condensor replaced. A/C working. Never had this problem with previous Impalas. Hope fixed permanently as don't want any problems when out of warranty.

It might be your blend door actuator, it is what controls your vent door from either giving you hot air or cold air. Sometimes the actuator might be going bad and let the door close a little forcing some hot air in. It is up under the dash and usually a pain to get to, a garage will charge you for probably 8-10 to fix so try and fix yourself (but).....check all your fuses first that have anything to do with the heater or air conditioner. Pull your climate control out of the dash make sure everything is still plugged in the back of it. After that your going to have to either look under the dash and see what moves when you move your climate control lever (you might have to disassemble dash not sure on your car) to see what is going on. You need to find out if your car operates the actuator by cable, vacuum or electric and go from there. It might be an easy fix, mine is a 1998 Bravada and there is a spot on the heater housing on the firewall (under the hood not inside the car), and on that housing it says (cut along here for access) well i cut on the line and there is some screws to take out, and then i have access to that door. I just opened the door so cold air was coming out all vents and then unplugged that actuator so the door wouldn't move and worked perfect until i could put new actuator on.

That's the garage will charge you 8-10 hours of shop time, which can be a huge bill to fix this, so exhaust all your options first!

A scan tool of the right type should be able to tell you if the blend door is actuating at its full range of motion or not.
