'99 mazda b2600 A/C wiring

[1600dave]

Hi guys,
Just thought i'd ask here as someone may have a 4x4 b2600/bravo.
firstly, i have tried finding courier/bravo/b2600 wiring diagrams/manuals, but cant find anything! if anyone has anything, i'd love it.

the problem is, my a/c compressor wont come on! not getting any power to the positive wire that tells it to do its thing.
fuse is fine.
there is a 4 pin connector in engine bay. wire colours are
green/red - comes from fuse box
red/black - dont know where this comes from
green/brown - dont know where this comes from
green/black - goes to a/c compressor

if i just from the fuse box wire to the a/c compressor, it starts going, so i know it does work!

with the car running and the a/c and fan either on or off, the fuse wire has power, and so does the green/brown.

the a/c switch inside the car has 3 blue wires going to it. the light comes on when i turn it on, but i cant get to it to see if its putting out a signal. i'd assume so.

problem is i dont know where these wires are going to. another relay or something, somewhere i'd assume. i cant find anything though.

and its damn hot!

any idea's?

thanks,
Dave

There should be a switch somewhere which detects gas pressure in the system. No gas, no compressor.

Sounds to me like you're out of gas.

could be very well on the money! it doesnt have any gas!
lost all that when i had to pull the radiator/condensor out to fix some stuff on the front of the engine. thanks for that, i'll check it out further.
