1997 Mercedes Benz E420 Base 8 Cyl 4.2L - Engine
Bad blower motor/regulator.
I bought blower motor and blower motor regulator from Autopartswarehouse and installed it. The fan blows from low to high speed is fine, butas soon as u connect the fan with the fan switch off, the fan will run on low speed. When u start the car and turn off the ignition switch the engine continues to run even when the key is pulled out of the ignition. What could be the problem, could it be the regulator has to be grounded?

    Its difficult to say what was gone wrong, probably its a bad wiring i suspect. A wiring diagram from your local library will be helpful to fix this.
