AC Compressor wont turn on
I just replaced my seized compressor and recharged the system but I cannot get the compressor to turn on.
I manually bypassed the pressure switch (shorted it) and nothing happened, so I dont thinks its a pressure issue.
I directly fed 12V to the compressor and found that it does turn on, so somehow Im not turning on a relay or a fuse is blown.
Could someone please help me to find where the correct relays and fuses are for the AC system. I looked at the fuse box near the battery and I dont see anything labeled AC. The fuse box near the clutch fluid reservoir has no label on my car, and I dont see anything relevant on the fuse box label near the clutch pedal inside the car.
Thanks in advance.
Also, I put in 1.4lbs of refrigerant, and It might be too much, the manual says 600g=650g in the beggining part, but then says 550g-600g in the AC section, I filled it to 1.4lbs which is 635grams.

With the machine that they had in the shop. I don't know the model number but a mechanic friend of mine who is familiar with the equipment did the work.
I believe we evacuated it, then vacuumed it for moisture and then recharged it to 1.4lbs

does anyone have a pic of the sticker which should be on the lid of the smaller fuse box under the hood.
And if the AC fuse/relays are in one of the other fuse boxes could someone please point me in the right direction, there is nothing on my stickers.

Did you ever find the problem? Ive been searching myself for some help with my compressor not turning on. system is charged and no leaks. How did you know your compressor was seized? I would assume it wouldnt allow the belts to turn which not let the car run.
