My 2000 ml320 has had an electrical drain that has come and gone for about 6 months. I have checked everything on this car over and over. Both fuse boxes and the only thing I have found was the ac blower motor that had a constant drain and pulled the fuse. It keeps coming back every few weeks. Someone posted a while back that the tele aid or whatever you call it could be a problem. It was turned off at a dealer 15 years ago but at this point I think I should just take it out of the car. any thoughts on this would be great. Also any pictures of it and where it is will help. Any other things to check will sure help also
