heat only working on high... help please

my heat is only working on high and it is not getting as hot as is usually does. it is way to cold to drive around with no heat. anyone have any ideas as to what is wrong?

are you referring to the blower setting high, or twisting the temp knob all the way to hot. For the blower, search for blower motor resistor.

yep. sounds like 2 problems. 1 is the blower resistor

thank u searching for blower motor resister got me results… i didnt know what to search for because heat not working didnt bring me results… much appreciated.

Do a radiator flush and fill. The type where you use a flush chemical to clean out the radiator. Make sure you run it in the system, with the heater set to “hot” and blowing full blast, to run it through the heater core.
