The front defroster in my 1998 C5 Corvette doesn't blow air on the driver's side so it fogs up. I removed the HVAC fuses (18 & 27 and 27 by itself) to reset the actuator but it didn't correct it. I could hear the actuator moving after replacing the fuse(s). The key was in the On position but the engine was not running. I just bought the car in July and it only had 45000 miles on it and looked immaculate.

I checked the DIC error codes but there were no HVAC codes and the codes that were there were all historical(H). I'm not sure what to do next and I don't want to just start taking things apart.
 
It's the actuator under the dash. The entire dash needs to be removed to replace the dead part

Moving to the C5 Tech forum for greater exposure...

Thanks smitchel87. I've been leaning toward that as the answer after reading many forum comments, I can hear the actuator moving when I reset it by removing the fuse but it doesn't correct it. The thing is I don't have any HVAC DIC error codes at all which seems odd. A mechanic friend of mine suggested rebooting the whole thing by disconnecting the battery for >12 hours and then touch the two leads together before re-connecting it, so I was going to try that as a last test.

If you don't mind me asking, what were the symptoms of your problem before you replaced the actuator?
 
Same as yours but I got codes too.. Strange
