Why is your steering so stiff on your escort in cold days and light when warm?

Normally in most cars, when it is cold outside, your power steering fluid is thick, thus, needs more presure to push it through the pump and lines. Same with any oil, in your engine. Once this fluid has warmed up, and you've made a few turns it should work properly. If this continues to happen, check your power steering fluid level, or have it looked at by a trusted mechanic. If you lose power steering, all together, it's not fun.
