Heater not blowing any air

Ever since i had the teg the heat only worked on the 3 and 4 position but just today it completely stopped working. Nothing on the heat and ac panel even lights up anymore. What could the problem be? I checked the fuses and nothing was blown and every search that i looked at only said stuff about no antifreeze or the heater core is clogged. It worked when i went to the store but when i came back out it didn’t work

That typing hurt the brain. Check your anti freeze first. If good, when it gets hot and a fan comes on grab your lower radiator hose. If its cold it could be your thermostat. Check the fluid first though.:rockon:

Sorry about the typing. I was pissed off and typing. lol The fluid is topped off. Do you think the cluster is bad and not turning the blower on?
