I have had my '99 E320 for about a year now, and it is a JEWEL. I do have one reoccuring problem with it, that I am going to have to get to the bottom of. Every few weeks the windows won't go down, the seat adjuster will be dead, the turn signals are dead, windshield wiper is dead, etc. Then out of nowhere, they all come back......for a few days. Then I lose the functions again. Because they come and go, I know it is not a fuse. Here is the big question; Because it appears that there is a loose contact that is causing this, WHERE do I look? I should preface all of this by saying that I am a female, and am not all that familiar with where things are on the car, so you will need to be specific in giving directions to me. I plan on taking the car in for a complete servicing shortly, but I would love to get to the bottom of this electrical problem myself. If I take it to the dealer and tell him this problem, no doubt they will try to sell me a complete electrical harness. lol. Help!
