Drove my "new" used 1990 Buick Reatta from Dover DE to Denver CO the past 3 days. The dealer replaced the blower motor just before I began the drive cross country. When using the ACC system manually to switch modes for air delivery between different outlets (Heat, Bi-Level, Defrost, Dash) the system did not redirect the air. Somehow either the heater box door is not getting the signal to change position(s) or it's blocked. Any ideas which it may most likely be and how to diagnose it without tearing the entire system apart? Thanks for any help! Mike 2 Answers
