The blower in my 2003 Dodge 2500 CTD worked intermittently for about 2 weeks and is now not working at all.
I tried to replace the resistor, but that did not solve the problem.
I have taken a voltage meter and used the ohm setting to check all the connections. I have good connections from the steering column to the motor, from the motor to the dash switch and from the dash switch to the resistor. I checked the resistor, the motor and the dash switch with no indication of a short.
It appears I don't have power to the blower. I checked the incoming green wire with the truck running and got a '0' voltage reading.
Do I need a new ignitiion switch? Multi-purpose switch? What could be causing this and where do I look next?
have the same problem?
