Turn Siganls wont flash

this happened to me on a bunch of other cars i've had... sounds like a blinker relay to me, if that's what it is you're looking at like less than 5 bucks and 30 seconds under your dash, good luck

Doesn't the four way flasher die and interfere with the turn signals? The one that is usually behind the radio or glovebox?

change your flasher under the dash

Do your turn signals light up and stay on? If so, this is the blinker flasher. They were mounted various places depending on the year of your car. Check behind the glove box, behind the radio, and above the brake pedal (under dash). It's a small round cylinder about 1 inch around. Mine was light blue and near the brake pedal.

With the ignition switch, typically you'll have no turn signals at all and the blower for the HVAC also doesn't work. If this is the case, turn the ignition to the "key on engine off" (KOEO) position and gently rotate the key back and forth. If the blinkers and HVAC blower start working, your ignition switch is going bad.

Regardless of any vacuum issue, the blower motor will still work. Without vacuum to the HVAC system, I believe the air will only blow out the defroster vents.
