DIAGNOSTIC PROCEDURE (MODELS WITH ZD
ENGINE)
SYMPTOM: Magnet clutch does not engage when A/C switch
and fan control dial are ON.
CHECK POWER SUPPLY FOR COM-
PRESSOR.
Disconnect compressor harness connector.
Do approx. 12 volts exist between compres-
sor harness connector terminal No.j
1and
ground?
No
cYe s
Check magnet clutch coil.
NG
Replace magnet clutch.
