2004 CHEVROLET TRAILBLAZER EXT Steering Problems

IN COLD WEATHER, THE STEERING FLUID BECOMES FILLED WITH AIR. THEN IT FOAMS AND BOILS OUT OF THE PUMP.THE CAR IS IMPOSSIBLE TO STEER. IT HAS DONE IT TWICE. *TR

MY 2004 CHEVROLET TRAILBLAZER HAD A SUDDEN FAILURE OF THE POWER STEERING PUMP. THE VEHICLE ONLY HAD 43,000 MILES ON IT AND FAILED WITHOUT WARNING. IT BECAME EXTREMELY DIFFICULT TO STEER AND FORTUNATELY I WAS NOT TRAVELING FAST AT THE TIME. NOTE THAT THERE WERE NO LEAKS IN THE SYSTEM AND THERE WAS THE PROPER AMOUNT OF FLUID IN THE RESERVOIR AT THE TIME OF FAILURE. *TR
