Some years ago, a mechanic "pulls the plug" so my car's speedometer
stops. It's been left like this for quite a few months before it's
pluged back in.
Since then, different lights on the dashboard turns on for no reason.
Another mechanic then suggest me to change the sensor (that plug).
That helps a bit, but now, the windshield fluid light is on all-the-
time. Now, another mechanic said it may be some salt (from the
winter) got into the socket (where the "plug" plugs into), so
replacing the socket should help.
Have anyone experience this before? Should I replace the socket as
what the mechanic suggested?
