Im Taking an A/C class For the next three Weeks So Chill Out for A while Until I learn How the Heater Works.. Which I think I Pretty Easy.....

Also Check If your blower motor Is working... I think All the Heater does is blow hot filtered air from the engine compartment.. I ThinK....

I just Started A/C Class This Week LOL:drool: :drool:

check and make sure your heater lines off of the block are hooked up correctly to your heater core. I didn't have heat for a while and it was because my lines were accidently looped instead of hooked up. Also, check to see if your radiator is at the proper level. Sometimes when its low your heater won't work correctly. Let me know whats goin on after that and I'll see what I can possibly do to help.

check for coolant leaking from under the dashboard on the passenger side. could be a ruptured heater core if it *suddenly* stopped working

[thx247]

may want to check coolant levels. Heater core is powered (warmed) by water coming from the engine block

well the heater used to work, so the lines must be correct, and i dont see any leaking coolant, the fan works fine, how much do new heater cores cost?
thanks

well found out i am leaking coolant, on my way 2day my engine was running extremely hot, like near the very top, so my destination was a mile or two, i stopped there and put some coolant in (after my car cooled off) and it fixed it, my car is leaking coolant somewhere soo.. its prolly in my ghetto-ized lines... thanks for your help guys!

my car same deal. Thermostat wasnt opening meaning the block and core werent getting hot fluid. Change your thermostat. half hour job.
