blower motorbecame very loud then just stopped working all together.
The blower is not working where can i find the resistor ive been test all airconditioning fuse and all of them is good.
Fan was becoming erratic and then suddenly stopped. Yet to be fixed.
Heater blower motor failed, also causing control module to fail
Clogged drainage tube caused a water backup into the resister resulting in a short circuit. Replacement was required.
heater blower motor needs replacing
aircon suddenly not functioning
A lot of noise in the ventilation system. Looks like the fan motor problem or it needs lubrication.
Worked this morning, wasn't working on my lunch break.
Blower Motor suddenly went out without warning. Currently looking for a cheaper than dealer place to purchase the Blower Transistor or Heater Control Transistor.
