1998 Cadillac DeVille Q&A

1998 Cadillac DeVille Question: How do I find out which door actuater needs replacing.

The heat does not come out of the dash vents at all. Works good in the floor and window vents. Could it be a vaccum problem. Would like diagram of actuater door location, and hopefully how to narrow down the location. Thanks for your time. FRANK -
