Hello
My 98 S-10 Blazer just stopped blowing air out on my feet. It blows
out the vent on vent setting and out the defroster on feet, blended,
and defrost.

Are there two damper flaps? and one is stuck/broke? Are they vacuum
activated?

What could be wrong?

Thanks!

I'm not expert on the S-series Blazer, but this is a common problem on
the Astro/Safari vans. In the case of the vans, it is almost always a
broken vacuum line in the engine compartment. I'd start following
vacuum lines under the hood first and make sure they are all intact.
(Note: GM uses some odd looking vacuum lines that are about the same
diameter of a heavy gauge [10/12] electrical wire and can be easily
overlooked.)

Wouldn't there only be one line run to the contol and if that did not
work I would not be able to switch from vent to defrost?
