Howling Noise from Power Steering
If you receive customer reports in the above model vehicle of a howling noise from the power steering system when the engine is at idle and the A/C
compressor is on, especially during parking; this noise may be due to the high-pressure expansion hose of the power steering system. To resolve, replace
the high pressure expansion hose of the power steering system. Refer to WIS document no. AR46.25-P-3015VTF.
