Heater fan does not work

you may need to replace the blower fan or the blower resistor

check blower motor spins freely
check fan switch and then, check blower motor power transistor.

The fusebox should be under the dashboard on the far left side. you might have to remove a small cover to access the fuses. On the fuse cover, there will be a small diagram, and it will tell you what each fuse is. The owners manual should show you the exact location of the fusebox if it is not under the left side of the dash.
Hope this helps;

If heater fuse in fusebox is good,try this,Key on engine off turn heater switches on high,tap on bottom of heater motor under passenger side of dash above right foot area. If fan runs replace motor.

did you tried to instal a new difernt power line to chek the fuel pump work? or do you chek if have pulses on the inyector rail or sparks in the spark plugs wires? maybe a fuse blow in fusebox or main fuse.i hope be helpfull

Hi there,

The fusebox lid/cover usually has the fuse layout inscribed on the reverse side - look for location of fuse, labelled TAIL or BRAKE lights.


Cheers,

Do you mean radiator fans or heater fans?

If radiator fans, they don't work all the time, but only when it gets too hot. When the car is not moving, they will usually go on eventually. But in normal speeds, you don't need fans.

If there is a problem, it is usually the relay, but could be the ground, one of two fuses, or the temperature sensor. The main fuse is a big one, because they draw more electricity then anything else. The switch is usually in the radiator, and powers the relay primary from a small fuse. The relay secondary then goes from the large fuse to the fan, and back through ground.

Let me know if you mean the heater fan.

check your fuses

check and replace the blower motor speed control assembly
