Ok so could i fix this easily if its stuck? like maybe tapping it or something? or should i just pay and have it fixed. But its just so confusing cuz people are telling me diffrent things..my thermostat is what i was told so my mom bought a thermostat. So i am wondering if i should go have that looked at. Is that pricey to have that fixed? the coolant thermostat that is? I mean cuz it has just been confusing the shit out of me. The A.C button light turns on and off when i push it. I been told a number a things it could be the thermostat...the heater core and the coolant theromstat. But i am needing to get heat in my car because my son is gonna be it in and i need heat. so i am wondering how pricey something like that be, i mean i am an average joe so i know i cant fix that.
