AC/heat 4th fan speed not working

[aj213121]

Hello, the 4th speed for my fan on my heat/ac is no longer working. Speeds 1-3 work perfect. I replaced the blower motor resistor already and just trying to figure out what's next to look at.

Thank you.

As it wasn't the blower resistor it might me the fan that switch is bad.

The switch on the interior of the car?

I had to replace the connector on mine. The connector on the resister. Was a couple bucks off eBay. Mine was pretty melted and corroded. Sounds about like what you got going on. Highest amperage draw setting can’t pull enough amperage through the dirt connection

Switch panel is the only thing you got left then. At least they are one of the easiest things to get at a junkyard just need a 7mm socket

Replaced the switch along with the connector. Still no 4th speed
