I have a 2004 Dodge caravan. It was whinning first thing in the morning whe the engine was cold. Once it warmed up the whinning of the power steering stopped. I did as was posted here and replaced the reservoir and that fixed the problem. Thank you all. This has saved me hunderds of dollars in repair cost. To placed the unit only took about 1 hour and cost about $40.00 from the dealer.
