i went to go turn the blower off (AC) and the blower fan wasn’t responding to me turning the fan speed knob. it stayed at speed 3 no matter what. i pulled the hvac controller out and the fan speed knob was extremely hot as well as the plug. the wiring didn’t feel anywhere near as hot. plug doesn’t look melted but hvac knob has seemingly some type of corrosion on one of the pins. i had it on speed 3 of 4 on my 30 min ride home. i changed the blower motor last year since it was original and caused high speed to stop working which i understand is a common issue with old blowers.
any thoughts?
