1) This can be a can of worms. Could be tires, could be suspension, could be both! To me it sounds more like tires though.
2) P0449. Very similar to P0440, this code for the EVAP system is a code that is telling you the system cannot close, therefore can’t build the proper and necessary vacuum in the system, which is measured in the tank. Very similar to having a leak in the system. I do not have access to SI here at this job, but later I can pull it for you. However, in the interim, read up on P0440 just as a general overview to understand the system.
3) Sounds like an actuator issue.

As to the Freon issue, Freon hasn’t been used since the early to mid 90’*. It’* all R-134a now. So please don’t tell me you put Freon in? I hope that’* just what you’re calling it. Freon in your system would totally jack everything in the A/C. Also, don’t overfill with R-134a. When re-charging it, you need to add compressor oil as well.

I CANT ALIGN THE FREAKIN VALVE LEVERS TO GET THE MODE ACTUATOR BACK IN. I didn't even need to take any of this apart, this is the only difficult one to get back on. Please help me... does anyone know how to position the valve levers to get the mode actuator back on?

alright well after 2 days and countless hours, everything is back together, and thanks to the help of everyone... I have A/C on both sides.

To answer the questions above, I just call it freon, I used R143a.. don't worry. haha.

and I finally went to walmart and got a tube with the gauge on it, so that I knew how much "freon" or R143a to add.

Thanks again to everyone.

Questions about any of the process, feel free to contact me.

Can you turn the door at all? Is it bound up, or just that you can't reach it? Is there enough room to wiggle the actuator some side to side to get it to line up? You would think that putting the same actuator back in would leave things in alignment. If nothing else, if you can tell what position the door is in, hook the actuator up and then adjust the temperature setting to try to get the actuator close to the position of the door.

I got it, but for future reference, the controls default to the defroster setting, so when you put the mode actuator back on, plug the wire harness in,to the actuator and set the climate control to defrost, then un plug the wires so that the actuator is in the deforst posititon. Then you put the actuator on, and everything lines up.

Glad that you got it. The information about the default position for the mode actuator I'm sure will be useful. Thanks for keeping us posted.

Edit - for the record for those who may read this thread, freon is a general term for all types of a group of compounds known as refrigerants. R-12, now being phased out is not the only compound known as freon. For more information - the following Wikipedia page will explain that. http://en.wikipedia.org/wiki/Freon Then, follow the link that says for the entire list of freons/refrigerants.
