| sorry but there is no compressor relay on this system.
The clutch is controlled by the A/C amplifier, which gets its signals from the A/C switch, Dual Pressure Switch (in AC,luggage compartment),Vacuum Switching Valve (controls idle),RPM sencor, and Temp sencor (in evaproator). The A/C amplifier to the best of my knowledge is behind the dash with the A/C controls. it should be a 17 prong plug for 4agze and 13 + 1 for 4age plugs. If I remember correct you said your car was supercharged so I will take you threw voltage checks on the AC amplifier
the connection from the wire harness side looks like a box two rows with the top two corners cut out looking at this connection the top row is 1-8 and the bottom row is of course 9 threw 17
The first five are continuity checks, terminals 4,10,11,13,15 are all checked to ground and should have constant continuity.
The next nine are voltage checks and will be checked on and off positions.
2-13 ignition on bat volt; off no voltage
3-13 A/C on bat volt ; off no voltage
3-13 econo on bat volt ; off no voltage
5-13 ignition on bat volt ; off no voltage
6-13 start engine aprox 10 to 14 V ; stop engine no
voltage
8-13 A/C on bat volt ; off no voltage
9-13 ignition on bat volt ; off no voltage
14-13 ignition on bat volt ; off no voltage
16-13 econo on bat volt ; off no voltage
the final two checks are resistance and the condition is constant.
1-13 approx, 4.5 k ohms
7-17 approx 1.5 k ohms at 77 degrees F
if all these readings are correct and the amplifier isnt sending voltage to the compressor your amplifier is bad. Hope this helps cuz I hate to type LOL |
