Heater problem
2003 Hyundai Elantra 4 cyl Front Wheel Drive Automatic 85000 miles

The heat output is stuck at mid-level/dash vents only and won't switch to floor, plus we also can't get much of anything from defog/defroster vents. Blower works at all speeds and temp functions properly. The mode selector switch SEEMS to work, at least partly, because the A/C compressor kicks in when moved into the defog positions. I can't find an adequate drawing/pic/diagram of what I need to look for and really can't afford the $500 estimate that our local dealer wants to fix it. First they'd want $126 just to run diagnostics! Please, any clues on where to look? Maybe a dirty connector? If it could be a dead mode actuator, would that be too difficult to replace?

99.9% of the time it's the blend door actuator, Hyundai does give this info on their location! Remove the trim panel by prying it off, it just pops into clips, then unbolt the unit. Then you might need to remove the glove box door and some minor bracing.

Here is a guide to help you fix the problem. Then see the diagrams and images below with all for the blend mode door actuator locations
