High Spead Fan 5 not working

[GangstaCowboy]

Hello-
Just replaced my blower resistor thing behind the glove box due to my fan selector not working on 5 and 2. Selector 2 works now but number 5 still does not work. Sometimes when I turn it to 5 and then turn back to 4 it doesn't work until I turn I turn it to 3. Beside checking the fuse panels is there anything else I can check before I start replacing more parts? Thanks in advance and Happy thanksgiving!

your fan switch is likely finally given out www.amazon.com/ACDelco-15-72275-Heater-Blower-Control/dp/B0012P2KB4/

check the wire connector on the back of it too and replace if needed.

on high, the resistor is usually bypassed.

There is only 4 fan speeds.

if he is counting off as switch position #1 then 5 would be high and 2, 3, 4 would be non high speeds. my answer is based on that assumption. it could be wrong. no worries.

Sorry yes it is the number 4 selector on the dial. I will update what I find.

Could also be a relay right near the resistor. I had that same issue, but because of what you're saying with #4, I'm also thinking it's the switch.
