Detroit ? Chrysler announced Wednesday it is closing all its North American manufacturing plants for at least a month, the starkest move taken by U.S. automakers as they anxiously await word about government loans.

All three companies have been taking dramatic steps as they struggle to survive the recession and U.S. sales have dipped to their slowest rate in 26 years. Chrysler and General Motors fear they might not have enough money to pay their bills in a matter of weeks.

Attempting to cut costs, GM was halting construction of a plant tied to one of its most important projects, the Volt. Ford also said it will shut down 10 plants for an extra week in January because of sluggish sales.

Chrysler said it would extend the normal two-week holiday shutdown that begins Friday to at least Jan. 19 at all 30 of its factories because of slumping sales.
