There is a supply vacuum line that goes through the firewall next to the brake booster usually. It sometimes gets disconnected or damaged. I fixed one on a 97 with 5.9l diesel that was on the right side of the engine going through the firewall as well. It had melted on the exhaust manifold. Either way, look for a line going into the firewall.
