Ac help!!

[Rob_hall57]

Hey guys! Needin some help with my ac. For some reason it just stopped blowing out my dash vents. It blows super cold but will only blow from my defrost and on the floor. Nothing out the dash vents. Any help or solutions would be greatly appreciated!

Run the DATC self test. I'd tell you how, but it's different depending on what year LS you have, and you didn't say. Search this forum for running the DATC self test for gen I or gen II, depending on which you have.
It's probably going to tell you that the dash actuator has failed. If it says no problems detected instead, then the actual air door have broken, and that's a bigger problem.

Sorry I forgot, it's the 2006 ls sport.

Okay I did the test and the error codes that came up were 12-62 and 12-63. Can't seem to find anything online telling me what they are. Thanks for the help!

Here's the troubleshooting for that.
