Saturn Repair Problems? Ask a Mechanic for Answers ASAP
It sounds to me like it's something as simple as re-calibrating the blend door actuator rather than replacing it.
Before paying the dealer you might try to get it to recalibrate it self. Sometimes it will work, sometimes it doesn't, but it doesn't cost anything and it certainly won't hurt:
Make sure the HVAC control module is off and the key is off and out of the ignition.
Disconnect both battery cables and then touch and hold them together for about 1 minute.
Reconnect the battery cables like normal.
Turn the key to the on position but don't start it.
If the HVAC module turns on by itself then just leave it alone.
If it doesn't turn on then turn it on and leave it there for about 10 minutes without touching anything.
Then turn the key off.
Then start it like normal and see what it does.
I wanted to see if you need any more help with this one.
Please let me know if you do.
