My heat/ac control knob that goes from 0-5, when i put it to 5 it just shuts off instead of full blast.

anyone know what causes this to happen, or find out maybe what caused it/how i can fix it.

i read through that, and it seems like they were having problems with auto hvac.

like i said it works completely normal in 0,1,2,3,4 but when i hit 5 it dies on me.

im going to switch out fuses today, if that doesnt work i'll look to see if my harness is melted (lord i hope not)
