AC Diagram

Anyone know where I can download a diagram of the AC system on 94Z28? AC blows cold but will not blow thru dash vents. This may be the wrong list but it was close.

Make sure the vacuum line that goes to hvac contol head (in dash)is not disconnected,pinched,or leaking. Thats how it changes the mode doors positions is with vacuum motors.

Re: AC Diagram

Can any body explain how to get into the dash, does it take a special tool are what? I have not tried to remove it yet as I did not want to break anything. [as I do not see any screws etc]!

B-4 you do that check the vacuum line under hood first. This is the place it is likely to have a problem.I think on it turns into a black plastic line & goes into firewall.
