Re: The a/c Compressor Does not turn on.
There is also a low pressure switch that is incorporated into your AC system. If you have lost to much R-134 the compressor will not engage. This is to protect the compressor so it does not seize up from lack of oil. Your AC system also has ester oil in the system to lubricate the O rings and seals to keep them soft so they seal. You can jump the pressure switch to override the low pressure. If the clutch on the compressor engages then you have a low charge in your system. Or, you can place a manifold gage set on the low and hi side of the system to see what pressures you are running. If you don't know anything about head pressures then don't attempt this process. Good luck.

Try unplugging the air conditioner compressor under the hood. There should be a plug near to its pulley. With the compressor unplugged, try turning the fan switch to AC again & see if it still blows the fuse. If it does, there's a problem somewhere in the wiring between the switch and the compressor. If not, the problem is in the compressor's pulley clutch.
Your compressor is not coming on. Test this by turning the car on and setting the AC to mac cold and out the top vents only. After 5 to ten minutes feel the low pressure AC line. Its normally the one witg the blue cap and has condensation on it. If it doesnt have condensation or doesnt feel cold, then the compressor may not be coming on. Also when there is an AC switch that axtivates the compressor when you turn the air on, this could be whats bad. If you know that the compressor is not comming on at this point, check your fuses for the compressor. Of you cant determine the problem at this point you may have to have it services.
First make sure the fuse size it correct. there may be a small ampere fuse when it should be larger
Then test your compressor. you could unhook the wires from the compressor (mark where they go and put some black tape on them so you won't short anything out) and then turn it on again and see if the fuse blows again. if it does not blow then it means that the compressor is bad.
if it does blow you may have a ground on the wires somewhere.
Look for a blown fuse or bad relay for the a/c in the front fuse box. If replacing fuse and it blows again, then there is a short circuit on the load side of the fuse which goes to the a/c compressor clutch. If fuse ok, try another relay to replace the possible bad a/c unit. The engine computer controls this relay. It also receives air temperature sensor reading from cold air path.
