a. try a new thermostat
b. take out the valve that allows coolant to the heater core and run a straight pipe (I did this)
c. take off the intake and exhaust hoses for the heater core put a pressure washer at the end of one of the hoses and letter rip. Sometimes a bunch of gunk comes out that is restricting flow.

I did all of the above to get my car to heat at all. It still didn't heat and I was pissed. Finally i grabbed the cable under the dash that controls the 2nd butterfly vent and tugged really hard on it and the vent opened. HEAT!

 

i had the same problem, except for me, mine didn't even get warm

 

remote start ownz.

 

as far as i know solution a and c work the best....
also if it's REALLY cold out your heater won't get hot untill you start revving the engine. if that doesn't help jam a peice of cardboard in fron of half of your rad. it'll help keep the rad warm when driving

 

Sometimes my car takes a long time to heat up, sometimes it doesn't. It's odd. But my heat can burn my hands if I turn it up to 4, I never even go past 2 or it's already too hot.

 

Did your heater core loose any coolant? You would know becuase of the coolant that would be on the floor of your passenger side carpet.
