Some customers may comment about various types of noises that seem to come from somewhere in the front of the vehicle or behind the instrument panel. These noises may be described as a hiss, buzz, rattle, or ground-out condition.
These types of noises may be caused by one of the power steering cylinder lines contacting the HVAC case (refer to Figure 1).
If a cylinder line is found to be in contact with the HVAC case, carefully reposition the line away from the area of contact. Avoid severe bending.
Start engine and check for leaks at the cylinder line connectors.
