W211 fuse 45 keeps blowing
Hi!
I just got my 03 220cdi wagon up and running after standing for a while, but one of the fuses in front sam (nr45, 7.5amp) keeps shorting.
The spesifications of what the fuse is powering is;
"AIRmatic with ADS control unit
Electronic selector lever module control unit (Automatic five-speed transmission (NAG))
Rear axle level control system control unit
Gear recognition switch (Sequentronic automated manual transmission (SEQ))"
I have tried this:
Changing and disconnecting shifter unit and everything around such as airmatic buttons
Tracing wires from shifter unit as far as i can reach inside dashboard
Disconnecting and removing TCU (passanger side)
Disconnecting and removing airmatic module (passanger side)
Pulling fuse 37 on driver side fuse box
Still no luck and 45 still keeps shorting. Ive tried looking for wiring diagram for this fuse, but internet and my diagnostic tool says different colors and pins, and i dont wanna start cutting wires if its not the right ones
If anyone have ideas or experience with problems like this, i would gladly appreciate some input
