2001 Monte Carlo Remember current flow through the cooling fan circuit is

2001 Monte Carlo

Remember current flow through the cooling fan circuit is different during low and high-speed operation.

When the engine reaches a predetermined temperature the low-speed circuit is commanded on, as the temperature of the engine continues to rise the high-speed circuit is commanded on.

When the high-speed circuit is commanded on the low-speed circuit remains on.

These faults can have different affects during both high and low speeds.

Z is open.

A is shorted to C.

B is shorted to T.

R is open.

C is shirted to D.
