Hey all, So my dad has a 99 150 with the 6 cylinder and his heat decided to not work I guess. I may be wrong but its something screwy with his heat, im pretty sure it doesnt work at least thats what I understood over the phone cant really look at it from GTMO haha. He said that he already replaced his thermostat and that didnt work and also I believe he said he blew are into it to try to clean it out..Any Ideas?
Is the truck reaching operating temp? There's plenty of different things it could be... Thermostat Water pump Collapsing hose Clogged heater core Stuck blend door Faulty climate control
