What do you drive? Are you low on coolant?

sorry,i drive '00 tahoe limited the coolant is not low at all it just seems like the coolant is not flowing thru the heater core or maybe it trapped in the h/c somehow even in park with engine running, rev. the engine you hear the coolant slushing in the h/c.

kinda hard to explain.

could this cause the ses light to come on?

thank you,
