RE: 1994 dodge dakota heater dosnt work
Check under the hood on the passenger side of the vehicle. It is towards the back of the engine compartment on the rear wall. You should have a rectangular plate fastened to that wall with a connector harness. There should be at least 4 wires coming off of it. mine has 5 because I have A/C and one of them turns on the A/C when the fan is running. Just unscrew that plate and it should come right off, but since it's machine screws, you might need a flat screwdriver to pry out on the screw as you're taking it out because it most likely has been driven in too far and the threads on the screw won't be catching on the threads of the hole to make removal easy. After you have it out, look it over and there should be coiled solid wire. That is the "resistor" there should be one wire for each fan speed setting for a total of 3 or 4. Check these wires to see if they corroded off their connections. You should have spaces available to make new connections either before or after the original connection. That's what I did for mine since I have been through that already. Mind you, this won't last for long. Mine lasted for a few months, then I just recently had to redo it. It would be a good idea to either replace it with a new resistor network, or do what I am doing an build your own and keep it out of the engine compartment.
