No breeze from vents at all
by: Paul

After having new fuel pump put in and charging ac, I am getting no air from any of the vents. The shop checked to see if there was a vacuum leak, but nothing. Is there a fuse that may be involved? The mechanic said there might be a device in the dash he can look at, but maybe there is an easier fix that I can do?

a/c not at vents
by: Ron RDE

you have a loose or broken vacuum line, in, by the heater box, or you have a stuck actuator door in the heater box, spray all the mving parts with a little wd40, remove the passenger side dash panel, you will have ful access the heater box, see if the activators on the box move when you move the dash slides for heat, a/c warm cold
