Having problems with your Chevrolet S 10 ?
Heat exchanger valve
\015 Is there one on an S10? If so... where is it exactly?\015
Check the hoses going in and out of the heater core, if they are hot on one side and cool on the other the core is plugged, but that should only happen if the radiator is rusty. It is my guess u have a problem with the blend door actuator that controls air temperature.
