: : my understanding is that the motor will keep firing until it reachs a : rest position -- think about a windscreen wiper that stops in the : middle of the windscreen. if you have time & like playing w/ little : motors, this can probably be fixed. otherwise do as i would get a new : one. the rest contact will close & all will be well.
Thank you Richard. You've got it! Right on! and so did my son, in about five seconds....... (Kids!........) With the ignition switch on (first position) and the noise emanating, he looked at the headlight wipers and noticed that the left-hand wiper arm was not properly "at rest". He moved the arm to the "rest" position. The noise stopped. "Mission Accomplished"!! Well.......... maybe not, but at least that little puzzle solved. Thank you again.
In the meantime I've disconnected the offending motor. while I think about replacing it.
