Power steering issues in the winter

I'm not a power steering fluid expert, but PS fluid does have viscosity and that viscosity will increase as the temperature decreases causing the fluid to flow slower through the steering system. When the fluid warms up, it would flow better which is probably what you experienced after that 30 minutes. If you haven't changed the PS fluid in a long time, maybe you should and use a synthetic fluid that is compatible with what's spec'd for the vehicle as they tend to have better performance under a wider range of temperatures. Also, the PS pump could be getting weak or not pumping efficiently due to contaminates in the fluid (some companies sell after market filters for the PS fluid).

Having that same issue recently in our new to us '06 ll bean. I think the owners manual called for dexron 3 ATF as the proper fluid. Will look into changing out the fluid with a syn version to see if that solves the prob.

Even if you change it out with the required fluid, that should improve things as your PS fluid was probably never changed in that vehicle. Also check belt tension/condition to make sure the pump is adequately performing. I've always changed out Dexron III on other cars I've owned every 30K miles for the PS system and never had any steering problems during Boston MA winters.
