My heater isn't blowing as hot as it should. I already checked the valve and it was opened all the way open. Any ideas, i guess it is clogged.
Do you think getting the sytem flushed would help?
P.s. coolant is full

 

if you do a power flush make sure to have the heater on full. its not the blower speed you are concerned about right? if the flush does not work you will have to replace the heater core!!

 

yea I hope the flush works, the speed is fine
