Tachometer and speedometer needles no longer illuminated. Removed instrument panel, removed needles, re-soldered new LEDs into needles, re-assembled everything. LEDs $5, find-point soldering iron $45, several hours of my time. Squeak from what sounded like driver sun-visor area when car goes over bumps. Removed headliner three times at attempts to resolve issue. Finally discovered squeak was from dash behind instrument panel. Removed instrument panel, found squeaking mounting arm, sprayed lube, no more squeak. Loud "bonk" sound from roof center when car enter or exiting driveways. Multiple unsuccessful attempts at resolving the sound, finally found cause as aged body foam between roof cross-member and roof sheet metal, the body foam sticking to then breaking away from the roof sheet metal when car body flexes. Culprit roof cross-member located adjacent to rear edge of moon roof opening. Used hack saw blade to grind away aged body foam, sprayed lube, no more "bonk." Squeak from roof rear when going over bumps. Removed headliner multiple times at attempts to resolve issue. Finally discovered squeak coming from upper rear windshield frame, confirmed by reading similar complaints in forums. Sprayed lube, problems solved. OEM subwoofer makes "tack" sound when playing audio. Installed used OEM subwoofer from EBay, problem solved. Vanity mirror light does not come on when mirror cover is slid open, as it should turn on. Removed stitching of visor fabric on the edge facing the rear view mirror, and pulled back fabric to reveal small hole for accessing the contact points of switch. Scraped contact points, sewed fabric back using ladder stitch. Problem fixed. Interior rear view mirror glass developed a flaky look caused by reflective backing going bad. Purchased similar part from EBay, disassembled faulty mirror, swapped out mirror glass. Problem solved.
