No blinking?
Did u flip the dials around, smack the dash a little, push the recirc/frsh setting, do any prior work in that area?
Does the ac actually turn on? Rpm will fluctuate if it does, plus the vents will blow.....cold....air.
Do your hazards work?
Clock work?
Orange?
Any symptoms leading up to this?
Does it come on when u select defrost?
