My blower fan only run on the 3rd and 4th gear.
Should I replace the resistor or I should consider something else.
Some says that if it's the resistor it will only work on the fourth one...
Help
Thanks

Blower motor resistors contain controls that determine air settings, each control on your dash relates to a resistor inside the Blower Motor resistor module.

The fact 1-2 don't work, is enough to say replacing the blower motor resistor module should fix the problem.
