AC is out now..aggghhh!!!

[jtgh]

ouch, im stumped.

rattle some more yards.

hope you can find it..

all the best

The fuses are good..check the 25a heater fuse located in the block above left knee in the cab under the dash. Checked the AC fuse under the hood. Both good.

Ohming the resister now.

OK resister is bad. Hope this is all it is. Then all I have left is the P0740 code to worry bout.

you need a better scan tool , that AZ tools is converting real suz code to generic.

the real code is more accurate.
A/C
the resistor will only kill AC on the dead fan postions.
so if fan it blowing , the A/C amp logic module will be satified for that 1 input.
three are other inputs. that must be correct or the clutch will not engage.

list:
1: motor not over loaded (ECU /AMP comms) or wide open throttle.
2: core (evap) not signaling fozen core (termistor) [we have spec and test)
3: Freon loop has too high too low pressure (direct killing of AC)
4: A/c special motor over heat sensor signalling overheating (or bad)
5:Heater Fan ON
6:Not cranking motor.


as you can see there are at least 6 things(maybe more) that can kill the A/C
or 6 things that can malfunction and kill it.
a test of the inputs of the AMP will quickly determine the reason
and the output of the pressure switch.
that is all for A/C electric side.

cheers.

Thanks, I'll be back on here once I get the blower going. Waiting till July 7th for the resister. Then I'll go down your list. THANKS AGAIN!!
