Blower Blows on High?

Blower not working on low and medium modes,but only blows air on high mode.

Its problem with blower motor resistor.

Most  of the time that the blower only works on high it is due to a bad resistor.

You need an ohmmeter to test it. If you dont have one or cant borrow one, you can pull the resistor and take to a parts store and they will test it for free for you.

If you have an ohmmeter, then you disconnect the harness connector to the resistor, and on the resistor itself, check for resistance between each of the terminals. If resistance is missing between any of them, then resistor is bad and needs to be replaced.


This details will help.
Thanks.
