This demonstration guide answers one field question about nests in blower housings and chewed kill wires. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with housing inspection before the first pull. That reading separates nests in blower housings and chewed kill wires from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the loom and housing as the primary path. If it is in spec, do not replace the loom and housing just to complete a parts list.
Repair the failed system
The usual correction is the loom and housing, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about nests in blower housings and chewed kill wires.
Stop before you make it worse
Do not starting a nested engine to "blow them out". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the loom and housing is corrected, convert the visit to a broader diagnosis rather than stacking parts.
