no flow to side vents

[johnsongang]

Just picked up a 90 B2 2.9L XLT. Its been sitting in a barn for near 7 years, and amazingly, just about everything works. One minor issue is that I have no heat to the driver and passenger side vents, Lots of hot air in the center dash area. I'm suspecting there might be leaves/debris clogging it up somewhere, but where do I start?

Are you getting any air flow to the side vents at all? If not, I'd say your ducts have become detached from the heater box. Unfortunately, if so, you're going to have to drop the dash to get to them. If anyone has info otherwise, I'd love to know.

Mine does same thing but the little defroster still works so idk.
