I started my car tonight and noticed despite the headlight switch being fully in the off position, my dash lights are on and my license plate light is .
Odd. Never saw that before. Headlight switch I imagine.... Thoughts? David Addedum-and saw what I thought was a wisp of smoke come from under my dash at the windshield....perhaps my imagination? |

Sounds like a bad wiper motor to me. A good one should read from power input to ground of at least 1.7 ohms or greater, like 2.0 ohms or more. 1.7 ohms with 12 volts = just about 7 amps. where 2.0 ohms drops the amperage to 6.0. Too much less than that and your 8 amp fuse will blow. When it is "0" ohms, well the amps go thru the roof! Blown fuse, burned wires, etc.
If you disconnect the bad wire from fuse #8 and power up the circuit, does the 8 amp fuse blow? It shouldn't! Tom |
