Wiring diagram air conditioner will not turn on.

Are the A/C fuses good? what transmission, auto or stick?
the first check is , does the compressor, cultch, engage
and spin the actual compressor main shaft at full speed.
yes, then loop is bad. (freon loop) (fan good)
No, then below is wrong. (electrical)
94/metro/swift
did you check pressures yet?
if not , then the hi/low limit switch may be open killing the compressor
so it dont self destruct, never bypass this limit switch.
the High low switch if open kills DC power to the A/C main relay. coil.
coil yellow wire must be at 12vdc or the loop has wrong pressures.!
dig,. it refuses to destroy its self. so kills the relay.

all posts, USA.
does the A/C lamp on dash turn on? if not the blower is dead.!
on the 94,(i dont have 93 drawings)
you can get better drawings for 94 at alldata.com, any time.
yellow wire is hot. (clutch dead)


the next point of failure is the car has throttle pedal switch
that is closed all time but wot, wide open throttle cuts AC.
so this switch can fail and cut A/c (USE A VOLTMETER) opens.
the clutch has its own relay, that is controlled by
the A/C amp module (better name A/C logic module)
it cuts A/C for many reasons.
we use a voltmeter at the AMP mod..

inputs that can stop A/C compressor, are:
1: engine overheat sensor bad. 0v , goes to 12v at 235F engine temp.
pin 9.
2: pin11, not 12v means dash lamp out
3: pin 5, transmission cut, or throttle pedal cut out (WOT).
4: pin 4 and 10 , evap core iced up cut, thermister sensor.
5: pin 8, lost 12vdc power.

The TCM cut out , to pin 5 is just for automatic trans, with TCM shifter electronics, it sends cut when the trans detects overload.
(hills? or tranny goes to limphome mode, {sick})
see amp below.
that is it, for electrics. answer my first questions for better answers.
