He says I need the following items: New primary and secondary condensor (the small radiator type things in front of my main radiator,right?), a dryer(the can thing to the right?), new o-rings and schrader valves, and however many pounds of new coolant.
I'm a commercial refrigeration tech, saying that i've never worked on a toy a/c but all refrigeration system work the same basic way.
Basically what he's saying is that u need to replace that condensor, i'm sure u could find 1 easily enough and hook it back up yourself, make sure the connections seal properly. A drier is only a filter, filters the moister out of the system. Since your system has been open to atmospheric moisture and refrigeration oil absorbs moisture, u should replace it. The O rings are probably the ones at the refrigeration lines that connect to your condensor, easy enough to find. The shredder valves are only the inserts where u hook up your refrigeration gauges, lol ther're excatly like the little valve cores in car/ bicycle tires, u know the ones, when u use your key to let air out of your tires, same valve. U could get those at any refrigeration wholesaler in your area, they'll probably just give you 1, or maybe charge u a 1$. The only problem with doing this yourself is properly leak testing and recharging the system, some special equip is needed to clean your system of moisture(needs to be evacuated to 500 micros) and then weighing in your charge. I guess you could repair it all yourself and leak test it with nitrogen and when your confident it has no leaks, take it to any refrigeration guy u see and offer him 100$ <img src="/forums/images/graemlins/ignore.gif" alt="" /> cash to recharge your system.
