Richard28 & george d............... I just had the wiring harness and fuse #44 upgraded on my 2000 ML430 last week under warranty. It is a known problem, but you have to tell them you've had problems with the fuse blowing for them to replace it. If you have a decent dealer it should be no problem to get done. Also got a new harmonic balancer and new window switches, windshield washer fluid tank, new rubber baffels on the sun roof, new power steering clamp, etc.
