Went to Advance to let them run a diagnostic check, one code came back and it was this "P1633 Manufacturer auxillary control input and output".

They couldn't tell me what it meant, can anybody on here????

I think this code indicates the voltage is low. I would check the connections of the battery and check the voltage at the battery. Could also indicate a bad fuse. Seems like a weird code to get with out a low voltage gauge or battery lite.

going with what he said also check when you first turn the ignition on if the battery light comes on at all? you could possibly have a blown bulb, or you could just throw a dmm on it and check voltage.
