thank you for showing us this burned connector repair.
Same exact connector issue is available with the DC in-tank fuel pump (passenger side rear seat).
> ROOT CAUSE ...
Electrical current is exceeded by high motor load condition.
-- Blower motor use tight dry sleeve bearings to acomplish high-load (lubricate dry shaft!)
-- Fuel pump pumping through 120kMi. dirty filter over heats on 2x current.
The actual fix is to reduce the load to normal levels.
> Funny Thing...
We know how excellent SAM's are at monitoring precisely load current... too high, too low except.Unfortunately blower & pumps are left out unmonitored. Go figure...
These circuits are only fused against short-circuits so vehicle tolerate abnormally high currents by developing poor connection.

Accessing the Blower Motor Fuse block??? 2014 ML350 W166
2014 ML350 W166 - I've gone into the battery compartment where the 40A blower motor fuse is located. However the fuse block is "hidden" next to the battery in a cubby hole there. After removing the battery there does not appear to be any way to access the fuses. Can someone give me some advice on how to access the blower motor fuse without removing the entire floor board and passenger seat?
Is there a way to check it while still in place?
Thanks!
