I've seen it happen many times on the older Caravans, if you hit a really deep puddle, the splash can knock the accessory drive belt off of its pulleys. You can just gently pry the belt back on, consult a service manual for detailed installation directions.

Belt is slipping because of wear or loose tension. Now it is contaminated with power steering fluid it needs a new belt. Clean the all the pulleys it runs on first.

If the belt gets wet and flies off, or starts to slip, the power steering and alternator will stop spinning causing this condition.

Check belts to see if they are still on the truck and spinning the pulleys of the alternator and power steering pump.

The most likely cause of your concern is a slipping belt. Check the power steering drive belt for adequate tension, and the overall condition of the belt. If it's shiny, cracked, oil soaked or frayed it should be replaced.

This is very common, Tires, especially wider tires, have hard time going straight through puddles. It is very common. You may want to think about thinner tires. Also, thinner tires go better through the snow as well.

pull belt off and turn pulleys until u find bad one. first start jeep with belt off and make sure its not in motor. check power steering fluid. dont leave motor running for 2 long with belt off

chances are the belt is getting so wet its slipping on the pulley causing you to lose power assist temporarily
