Question about 2002 Chevrolet S-10
When the setting is on the vents it blows a little bit hotter. As soon as i move to floor of defroster of floor defrost setting is blows cooler than when set on the vents.
You may have a problem with the blend door motors on the side of the heater box. As one other person said: "Look at the controls right above the driver's feet area toward the heater box". If they are moving properly all the way, when you move the selectors on the dash, then there may be a problem inside the heater box. If they don't move all the way, then the blend door motors may be bad or binding. Another common problem on these is the control head on the dash not working properly. The control head can be diagnosed with a scanner that can read codes for it. Hope this helps out.

Your dial in your truck works off of a small vacuum line switching the gate for flow. I had the same problem in my s10 truck and it seemed like after a minute or so i would finally work. Come to find out there was a small rip in the hose next to the dial causing a leak.

Did this problem start after the battery was disconnected?
For the digital system disconnect the battery again for a few minutes, or remove the HVAC fuse for 2 minutes. Reconnect everything with the ignition off. Then turn the key to the RUN position, but don't start the engine. Don't touch the HVAC controls for 2 minutes, and you should hear the actuators and blower motor going through all the modes and speeds. This is recalibration. If you touch the controls during this time it will fail and you will have still air/flow problems.
If this does not solve the problem, you can take the dash apart to observe the mode actuator. It may need to be replaced. You may see it at www.parts4chevys.com or eBay.
