AC blower has 5 speeds: 1 & 2 don't work, 3, 4, & 5 do?

Hello, could be some kind of concern with a blower motor resistor or an automatic temperature control concern. Hands on testing will be needed to determine what area to focus on - so that you can see what is happening and determine the cause while it happens. I would guess the climate control is confused as to the blower speed desired, since the blower works anyway. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
