so i tried to flush my heater core and nothing came out of it. my heater blows sort of warm air when my truck has been driving for like ten miles. it also doesnt even warm up to the proper temp. the needle sits almost half way in between first and middle line(where it says 210). what else should i try?

What do you mean "nothing came out" as in plugged or just no gunk?
Are the vents working in relation to the setting on the controls?
I would be checking your thermostat, could be stuck open. If you have a 160 ditch it, if it is a 180 heat will be marginal on really cold days.

ya no gunk came out it was just clear water. my air controls do work because when i turn it to ac it gets colder. i recently changed my thermostat and i think the guy said it was aa 195. i got the oem one.
