First thing to check is the vacuum lines coming from the intake manifold, to the A/C controls, to the vaccum resivoir. Lots easier than it sounds!
The hose comes from the intake manifold (top of the engine) on the drivers side toward the rear and goes across the power brake booster. The booster is a large (~12" in diameter) round metal object mounted in the engine compartment right in front of the driver. The hose goes to a "T", with one side going on to the resevoir in the drivers front fender, and the other side going to a vacuum line down below. Both are easy to get to, and will probably be dried out and cracked. This is very common, the vacuum lines are available at any auto parts store, and shouldn't cost more than a couple of bucks. Takes about 10-15 minutes to fix.

My IAT Sensor is causing my check engine light to come on. Does anyone know where this is located?
