Replaced the intake gasket on my truck yesterday and got everything back together and running, well I only have defrost now. Im guessing its gotta be a vacuum problem and was wondering if anyone would possibly have a diagram showing all the vacuum lines that may have been broken.

Spray some carb cleaner around the hoses to see if one is loose or broken, also the vacuum lines are pretty well formed to fit where they go.

If you're sure it's due to the intake work, there are only a couple of options.

From the intake vacuum tree, you'll have several lines that aren't involved with defrost - brake booster, cruise, egr/smog, bmap, fuel pressure regulator, maybe more.

The one to look for should be going toward the passenger side firewall near the heater core/blower motor housing.
