If it is just a fluid issue, the problem is that there is air in the system, and every time air gets to the water pump, it can't pump anything. You need to pull it up on a sharp incline (as close as you can find to 45 degrees, run it for a bit and then turn it around on the hill to force the air out of the system. HOWEVER, I'd bet that it's the water pump. The water pumps used at that time had plastic impellers, and they disintegrate and little chunks get all through the coolant system. The dealership wanted almost $1,200 to replace it and I had to leave it for a week. I limped down the street to Firestone Auto Care and they did it for $450 in four hours. 50,000 miles later, no problems.

there is probably nothing wrong with the compressor the pulley cab be removed and the bearing replaced if necessary if the clutch coil is going to ground and blowing fuses then that also can be replaced all without removing the compressor from the vehicle the not blowing cold air could be that the ac clutch is not engaging either fro going to ground or a faulty ac relay that is going to ground I suggest that you find an accredited ac specialist and get a proper diagnosis and a quote first as the replacement compressor ( if a different gas is used ) will require a complete system replacement and not just the compressor as proposed even then compressors are not cheap so checks first may save you lots of cash

the codes refer to random misfires misfires come from plugs, ht leads , fuel pressure , injectors, coils As it heats up I suspect that you have a problem with an electronic component breaking down such as a coil/s, ignition module, fuel pump, or injectors

duh take a chill on the shop unless you want specific ideas of how to align it
