Chad, Do both of your headlight doors sag? Or just one? I think the buzzing you hear is probably the warning buzzer to let you know your headlight doors did not come up. Chrysler was smart enough to put a warning buzzer in the cars with hidden headlights in case the doors didn't come up and you were driving down the road thinking your lights were on, but in truth you had no lights because the doors were shut. There might be something impeding the doors from going up all the way. On my 71, there is a sheet of metal, painted black, that is attached to the back of the door to make the headlights "invisible" when looking at the front of the car. This little piece of metal is held on by very tiny pins and sometimes they can get loose. If the backing is loose it can get stuck as the doors rotate up. If the doors do not go up all the way there is a knob, I believe, under the hood on the motor that will allow you to manually open them. I don't know if it's a good idea to push on the doors themselves--? MM Chad Zeilenga wrote: > Recently my 73 Imp has been making a slight buzzing > sound coming from under the dash.
