Is this an electric fan MOD to make the fan run constantly?
The electric fan comes on when the ignition key is turned on and runs constantly until the ignition key is turned off.
I think I verified that this added relay is a bypass for the electric fan.
When the added relay is disconnected the electric fan does not come on.
When the relay in the PDC is removed the electric fan des not come on.
We have replaced the sensor in the thermostat.
I have replaced the relay in the PDC.
Since it does work with the added relay....does that mean it is the ECM and it needs to be replaced?
When the AC or defroster is turned on the electric fan should come on, right?
