Background : 98 S500 80,000 miles , owned by my 85 yo grandmother and is rarely driven. I went out to start it and of course the battery is dead. I charge the battery / take it for a wash and find that the power seats/mirrors/ steering wheel are not working. Check fuse , its blown. Try putting the spare fuse in and it blows , buy a few new fuses and the same thing happens what could be causing this?

Also I had asked about a year ago about the truck , it is no wanting to shut. The power assist doors work fine and the truck will work sometimes but most of the time I have to slam it closed and the handle never retracts into the deck lid. I have tried pulling the fuse for the assist pump but this does nothing. Also sometimes if i slam the trunk closed and then start the car it pops open again? Any ideas? Go to love the W140s. She spent $4,000 on servicing the car a year ago but it has not moved 50 miles since then. Also the blower motor for the A/C and heat is not working, anyone have a blower motor?
