I have a 1993 S-10 pickup. I bought the vehicle used. Shortly after my
purchase, I noticed a hissing sound coming from the central vent. Recently,
I've experienced problems with the ventilation in general. I get air from
the floor vent but not the middle and side vents. Any ideas what could be
causing these problems?

Thanks

Chris

YOu have a crapped out Vaccumm(spelling sucks) hose under the dash. Usually
the VAC connector behind the dash is the problem (its connected to the hvac
control and has about 5 vac connections to it)
