I have a 2004 chevy trail blazer it wont heat very well only luke warm air I have changed the fan thermostat and water pump


Possible plugged heater core. Check heater hoses when engine at operating temperature. Both hoses should be close to the same temperature. If one hot and one warm/cold, suspect a plugged heater core. A backflush will be required to correct the problem if it is plugged

I put a new heater core in my blazer and now the heater is blowing cold air why?


You need to verify that warm coolant is getting to the heater core by touching the hoses going into the firewall. If they are both the same temp or close, you might have a blend door actuator broken or sticking that does not direct warm air into cabin area

Is the fan turning on? I assume so.. when you change the hot/cold selector do you hear the flaps inguage? could be the linkage there. Otherwise, check your coolant level - make sure your heater core isn't plugged (let engine heat up, then see if the heather both heater hoses going into the firewall are warm). If one is colder than the other, flush the heater core.

2006 chevy silverado 2500hd truck heats up to operating temp while in parking lot blower works well but truck will not blow any hot air until truck is driving at at least 15 to 20 mph. fuses good think...


If I understand you correctly, your temp gauge shows correct operating temperature, your blower fan blows air that you can feel with your hand from the right floor or dash outlet, but that air doesn't feel warm until you are moving?

If so, several possibilities come to mind. One is that your coolant level is low. Even though your temp gauge reads in the right range, the coolant level could be low enough that it doesn't reach the heater core until there is enough engine RPM to create more pressure from the water pump and force what coolant is there toward the heater core. Another possibility is that your heater controls are not able to do their job. A stuck flapper in the duct or a malfunction with the temperature control system could be causing the problem, and at 15-20 MPH there is enough air coming through the outside air vents to provide some heat.

I'd check the coolant level first, though. The other possibilities are more far-fetched.
