Weird AC fan issue

[Mr.Clean16]

Hey there, I have a weird problem with the AC fan and AC light/button.

Turning on the AC and the light comes on the AC button as it should... Fan settings 1,2&3 do not work at all. Fan setting 4 works fine but when it's clicked to setting 4 the AC button automatically shuts off.

To summarize : AC technically works because leaving it on settings 1,2 or 3 its cold but not blowing the cold air because fan is off. Clicking to 4 blows the cold air out momentarily but then it goes stale warm because AC switch automatically gets shut off.

Hopefully someone can help. Thanks so much!

Blower motor resistor/relay. It's melted or otherwise not working. You can test your actual A/c is working with an infared temp gun if you had one. Or FLIR (Hey it's not that expensive anymore)

Make sure if you mess with it, or anyone for that matter, disconnect the battery. Might just need some CRC contact cleaner. Rust + corrosion is brutal for electronics on these cars.
