ISSUE:
An auxiliary blower motor that only operates in the high speed mode may be caused by an open thermal limiter on the auxiliary blower
motor resistor. The current location of the resistor does not allow the thermal limiter to properly cool.
ACTION:
Install a new blower motor resistor in a new location to achieve better cooling of the thermal limiter. Refer to the following service
procedure for removal and installation instructions.
1.
Remove the auxiliary "A/C-Heater" or "Heater" cover assembly.
2.
Disconnect the blower motor resistor wiring connectors.
3.
Remove the resistor and two (2) mounting clips from the resistor mounting posts.
