Need a 99 E430 Blower Motor wiring diagram..
I keep blowing resistors every couple of months and have come to the conclusion I might have a wiring problem.
If anyone has the wiring diagram for this I would sure appreciate it.
TIA

If you keep blowing them you are much more likely to have a bad blower motor than a wiring problem, start by removing it and spin to check if there's excessive resistance it should do at least one full turn if you spin it with a bit of force, if id does not, you can try to free it up with some WD-40 as a temporary fix.
I attached a wiring diagram, blower is page 2, wires 4 and 3 are control they should have between 0 and 6V depending on the speed chosen(7 speed increments: 0.8, 1.0, 1.5, 2.3, 3.2, 4.0 and 6.0V)
Good luck.
