Above is my last post on the noise i have had for two years, thats how long its been until last week... in the past all the electrics disconnected under rear seat, P/S rear door panel off... rear seats out... its sounded like a electrical noise like when a radio is searching for station that the best i can describe it..
So when i came to a stop in drive just touching gas i turned my head and listened.... Dam its coming from under the head liner, got into rear seat and pushed up on the headliner just behind dome light, it sounded like a metal crunching noise like strips of thin spring metal moving..
That noise was or is the spring clips holding the center dome light in.... pushing up made the creaking noise, pulled it out and didnt want to bend the clips might screw them up...so i put some very small pieces of paper where it clips onto the light, this solved that noise but was not what i was hearing prior.... i must have disturbed something pushing up on the headliner...
Few days later noise was back so i was wrong in my diagnosis ... back on the highway again all quiet, parked up for a few hours, started up turned lights on, as i was building up speed to the freeway noise came back again, getting off freeway at about 30 mph noise went away... still troubleshooting this...
