HVAC ISSUES.

2006 Mercury Marquis

When I start my car up and turn on ac or heater, it blows out nothing as if it's congested/clogged on all cycle modes and will do this for like 5 minutes then blow out as normal for a few minutes then back to congested/clogged blowing. What can be causing this and how to fix it?
