So when I was leaving college today my lovely jeep spat a beep and 2 lights at me. The check engine and check guages light. I checked codes and got the following (a lot =[)

0443
0481
0499
0622
0645
0688

My question is....what now? I'm unsure of all of those and don't know what they signify.

Also note that the cooling fan is running CONSTANTLY. Not sure what's going on...
