    Does it have automatic temp. control, or manual temp. control? I mean does it have a digital readout for the a/c or does it have knobs?

Where do I find more information on where the temp. door is and how to replace. I have tested the temperature control and it works fine.

O.K., there are two things that can cause this problem. The first, and most common is the control head itself. The other is the temp. door on the drivers side may not be closing all the way, which would mean that there is a problem with the actuator that controls that door. The only problem with both of these is that the only way you can test either of them is with a computer.
I have seen both of these cause a problem, but have seen the control head fix about 7 out of 10 times. If you just wanted to try something I would say replace the control head. If it turns out that the actuator is bad, then the whole dash will have to be removed to rapair.

    The control head is mounted in the dash and is what you use to adjust the temp, and fan speed. Should be right inder or above the radio.

Automobile air conditioning on max cool, blows hot air on passenger side tried dual climate control settings still cold on driver hot on passenger

I had the same problem when i was working on my 1999 Buick Regal and had to disconnect the battery. I didn't reconnect in the same way that I disconnected the battery from the terminal and noticed that the driver side had no heat or air but the passenger side did. I then disconnected the battery again and reconnected it the same way and now have heat and air on both the driver and passenger side. Hope this helps. Good Luck!
