my heater has been blowing warm and cool air and now it's just blowing all cool air. my cousin who fixes on cars told me i needed a new valve behind the dashboard. he didn't check, he just went by his own opinion. my private mechanic looks under the hood and he thinks it's a loose vacuum hose. ive been living in the North for 2 years and when i first moved here, my heater started blowing warm air instead of hot. i had my thermostat replaced about 3 times since ive been here. i went to an auto shop to get a third opinion and i told the shop mechanic all of this and he said i need a coolant flush. im asking a 4th opinion, what do you think i need. im very much confused!!!
