2004 E500 4MATIC Sports seats.

The heated/cooled seats keep blowing its fuse then I realized yesterday the fan on the drivers side is stuck on. It stays on until the fuse blows.

Can anyone link me a diagram on how to tear this thing apart and a schematic of the electrical?

Man, the 2004 E500 4MATIC is notorious for its finicky electrical systems. With the driver's side seat fan stuck on, you're probably dealing with a faulty seat control module or a short in the wiring harness specific to that seat. These high-end vehicles often have overly complex circuitry, and a malfunctioning relay or a damaged temperature sensor could also be causing the fan to run continuously, blowing your fuse. Given that the heated and cooled seats are both involved, the issue might stem from a central climate control unit that's sending incorrect signals to the seat fans. You should probably run a full system scan. There should be fault codes on at least one or more control modules related to this. You will either need to take it to the mechanic, but if you want to figure this out yourself, then you will need to get a full system scanner. the "youcanic full system scanner" is very good at diagnosing all systems, and there are other scan tools that can do this. Just be careful to use a full system scanner or you may scan the car and see no fault codes, as some scanners cannot read all vehicle systems.

All you need to do is replace the faulty seat blower regulator located behind the applicable seat-----remove the seat back lining and it becomes obvious bla bla
