Blower Doesn;t Work - But Does!!
Use a 12 volt test light (not a DVOM) between the terminals at the blower motor and the hot lead to a body ground. Take care not to spread the female ends.
Was this car in an accident? Check for pinched, nicked and corroded wires. With stranded and corroded wires it is possible for you to read voltage with a DVOM but will not operate a load (blower motor/test light) because you are not getting enough current.
What we've got here is... failure to communicate. Some men you just can't reach. So you get what we had here last week, which is the way he wants it... well, he gets it.
