+1 on the dirt dobber nest. Lost 2 blowers at once due to those little bastards building their nests on the fan blades.

Its probably that ECM reflash that failed and shorted out the blower sensor's, post your serial # of the engine so we can help

The jist
Fuse protected ? What size fuse ?
Dirt dobbers like to nest in them and or in the hose ducks
restrictions in the air ducts or vents and or again nests of some sort built in them or ducking from whatever ie animals - dirt dobbers, rats I have even stuck in them.
plastic bags or whatever gets sucked up into them or the hose ducking - check for any restrictions.
next when blowers turn on, the end vent hose portion can get sucked up against anything - the bilge floor, a stringer, a bulkhead or whatever creating a total restriction of air movement thru the blower inwhich causes them to run very hot. very common - the reasons installed vent hoses improperly or to long or end of vent hose not sucured in place that gets sucked up against whatever when the blowers are turned on,
or the vent hoses collapsed
Most of the time its installer problem that caused this for brand new installs that fail in short order.
or a wiring problem or fuse problem ie voltage problem of some sort as well

You'd almost have to disassemble the motor, look at the brushes, and look for missing shellac/black marks on the coils to figure out the failure. Most of the DC motors failures I've seen were crud/sticking brushes (R/C motors, drills, etc).
I say toss a set of 35k rpm Dyson brushless motors in those bilge blowers with billet fan blades with lithium ion batteries. Pimp.
