A/C blowing warm , temp dropped then skyrocketed, lost steering.

Goodyear says crank shaft tie broke. 500$ to fix. Say they can't tell what else is wrong till they fix that. I'll ask about belts. Thanks.

Suspect the crankshaft 'harmonic balancer' is the culprit .. That's what drives the belt and is fairly common for this part to fail .. *Strongly* suggest getting another (INDEPENDENT) shop to give you a price on the repairs!!
