Try the TSB info that Mik3y posted above first. This cures the squeak if it is coming from the cabin side of the dash seal. My noise was coming from the same seal but on the engine side of the dash seal. It's easy to see and get to. Have someone move the steering wheel back and forth while you listen for the squeak under the hood.
