Blower motor/3rd fan speed not working

[bfiakas]

On my 88 B2 the 3rd fan speed setting stop working today and what is strange is that the 2nd speed was blowing harder than usual this morning and then later today the 3rd setting stop working.Could it be the fan switch or the resistor that would cause just one fan speed to stop working?

Resistor on the firewall heater box.

I found that the resistor connector needed to be replaced.

Did you get a new connector? I saw Rock Auto also listed resistors with replacement connectors.
