The fan in the front doesn't turn on.

In the past, the fan would turn byitself after driving for a while, but now it doesn't happen anymore.

The back fan/AC is blowing just fine.

Fuse seems alright, also, I tried replacing the blower motor resistor but it didn't help.

Any ideas on how to fix that?

 

Most likely the blower motor is bad and needs to be replaced, but you’ll want to verify it’s not a wiring or control module issue first.

Unplug the blower motor. Inspect the terminals for signs of overheating such as a bluish color or melted plastic on the connector. If that’s ok then use a test light in place of the blower. Turn the key on and cycle through the fan speed settings - the light should get brighter and dimmer relative to the selected speeds. If that checks out, replace the blower.

I know you said you already replaced the resistor, but it’s recommended to replace them anytime the blower is replaced. If it’s less than a year old though it’s probably ok.

 

I will try. Thank you GumbyRT!
