my heater blows but not hot what do I need to do in order to fix it.

 

Sounds like you need a new heater core. That involves removing the dash to replace it.

 

I would guess its a heater core as well. Did you feel the heater hoses in your engine compartment to see if either of them have fluid going through them??

 

peak makes a radiator flush that you put in and run for 2 hrs and it really helps. I used it when my heater core was bad and it actually cleaned alot of junk out of it and the heat started working again. Check your autopart stores they should carry it and its alot cheaper and easier then replacing the heater core

 

NO check your heater core i replaced mine and it was full of crud. Put a new one in and blows hot again
