Start by flushing your coolant system and replacing your thermostat. You may later find that you have a clogged heater core.

SOURCE: need instructions for replacing heater core on 2003 Chevy S-10

The heater core may be behind the dashboard,passenger side. If you have never taken one out before,it may be best to take the truck to a shop.

How hard is it to change a heater core for a 2003 chevy trailblazer ext lx with the 5.3l engine and rear air? I have changed the heater control valve 3 times over the life of the vehicle and it is now...

Thats every bit of a 10 hours job, and thats if you know what to do and you have all the tools.

It definetly sounds like you have a leak, but would not say right off its the heater core....the control or a hose could be leaking....I would check those first.

No heat in my 2002 chevy s-10. Already changed

The heat is controled by a control valve installed in one of the heater hoses. It normally is controled by eather a vaccuum line or a cable coming from inside the truck at the dash where you slide the hot to cold adjustment.Find the valve under the hood at the hose,have someone move the control inside the truck.If its vaccuum you can pull off the hose and see if you have vac.If its a cable you should se it move.

Can get no heat

If the car is a 2000-2003 then first of all by disconenecting the battery you sometimes have to reprogram the heater control panel. This is done by running the a/c fans on hi and temp on lowest setting, then press and hold the temp settings to hot and continue to hold 10 seconds after it reaches max, then back to cold and hold for 10 secs, back to hot and hold for 10 secs then back to cold.
If this does not fix the problem then more and likely the car is going to need a heater control valve which is located on the right front lower corner of the radiator.
In replacing the heater valve you should also take off the heater pipes (quick connect) going into the heater matric and flush the system through, the system with time gets clogged and can prevent the coolant to flow freely and can also damage the heater pump assy which is next to the heater valve.
Hope this helps
Thanks and good luck
