SYMPTOMREMEDY
Radiator fan does not run at all.Perform the procedures in the flowchart {see page 22-8).
Condenser fan does not run at all,Perform the procedures in the flowchart (see page 22-1O1.
Both fans {radiator and condenser) do not
run for engine cooling, but they both run
with the IVC on.
Perform the procedures in the tlowchart (see page 22-12).
Both fans do not run at all.Perform the procedures in the flowchart (see page 22-13).
