No heat

My heater just quit . Was fine last night? No fan? Fuses okay??Any ideas

i got a 98 f150, same here, got heat, no blow, damper door shuts on its own, resets when i turn truck off for a while, NO CLUE. maybe relay switch? ne ideas?

Zip , possibly the blower motor has seized up and blown the resistors (depending on make and year)

Could Be The Resister Or Fan Switch. Try By Passing Both Connect The Fan Strait To The Battery
