I've got a vn commodore with a fan that doesn't work on 4.

I can get a the resistor array which is apparently the most common fault that causes the fan to stop working. I'm wondering how I test as to whether it is the cause or not.

I have a multimeter and there is no open circuit between any of the contacts. I'm wondering if it's possible to find out what resistance should be between the contacts or whether there is some other way of testing whether the array is in working order.
