My heater only works on a rare occasion, can feel the heat coming through, but nothing blowing out. Any suggestions?
Also check ✔ out the water pump. My heat was going whacky too- mine turned out to be the water pump. (125,000 miles) I'd try the core first.Around 120,000 miles. It does turn on and blows warm air occasionally and there's no rhyme or reason to win it works. When it does come on. 🤷
