I have a 1999 Cadillac STS I’ve changed the actuator behind the glove compartment because I was just kidding cold air instead of warm air. Now I have no air coming through the vents blower is working fine but no airflow through the front vents at all. I have change the cabin air filter is all three of them this is not the problem. Please send pictures And instructions how Find and replace the mode actuator which I think it is.


It should be similar to this repair on a Deville.

It is not an easy repair at all (physically challenging). The alternative is to remove the entire dash assembly.
