Car is a 9-3 1.9TID MY07.5
Problem has been around for sometime,last summer I swapped the control relay(706A) on the fan housing hoping to cure it as all the electrical tests in WIS fault trace seemed OK.
Decided to have another go this weekend
So I swapped the ECU last night still the same thinking it might be a control resistor.
All fan activations with Tech2 work apart for control 2
I measure 5v across Pins 3/4 on activation.(ie activating control 2)
Is this a wiring problem from pin 4 back through to 69 at the ECU?
Got me stumped!
