blower works when ignition on ACC but not when on RUN
Weird one for the forum. The blower works fine - so i turn the key on to ACC - blower works ok - all speeds. Then i go to start the car - blower cuts out - when car is running, blower wont work - turn key off - back to ACC - blower cuts in again.
Is the blower wired via the IGN switch other than ACC / Start ? cheers |
IGN turns the voltage access on

It means that when the key is in the on position it allows voltage to be accessible throughout the car and that means that voltage is accessible when you turn the AC on---think of the ignition switch as a light switch---what happens when you turn the wall switch on and there is no light----what two things could be faulty?

Maybe i wasn't clear
Blower works fine and there is power . All works when the ignition is on accessory position. when I move to start positon and when engine is running , blower stops. Turn the car off and key back to accessory, blower works again. So that's my issue .why does the blower work except where .car is running ? |
