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?
