My 2002 chevy avalanche is in 4 wheel drive low and will not go back to 2wd. (1 answer)

It has been difficult to switch between 4 low 4 high or 2 wheel drive for about a year. It would do it but it took many attempts before it finally clicked. Now its in 4 lo and when you hit the button you hear clicking then it just stops and stays in 4 low. I don't have any codes or problem...

2005 Chevrolet Avalanche 1500 Recalls

Fuel May Leak from Fuel Rail

The retainer clip for the fuel rail pulse damper may fracture and allow the damper to come loose from the fuel rail. A fuel leak in the presence of an ignition source may result in a fire. Dealers will replace the engine fuel rail pulse damper free of charge. The recall began August 31, 2006. The GM recall number is 06080.

Rear Seat Belt for Smaller Passengers May Not Fit Correctly

The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005. The GM recall number is 05037.

Hydraulic Brake Booster May Fail

On vehicles equipped with the Bosch hydraulic brake booster, the boost pressure accumulator may crack and break away from the hydro-boost assembly during normal operation. If this were to happen while the hood is open, fragments from the accumulator could injure people standing in the immediate area. The loss of fluid while driving would cause increased steering and braking effort and a crash could occur without warning. Dealers will test the hydro-boost assembly for function of the two-function valve. If the hydro-boost assembly fails the test, it will be replaced free of charge. The recall began March 23, 2005. The GM recall number is 05006.

I love my Chevy Avalanche, it is the most versatile vehicle I've ever owned but I have one complaint. It is on my mind right now as winter is beginning. In the winter the tailgate freezes closed and when I do get the door loose, the latch freezes so the tailgate falls open when I drive. Sometimes the handle frrezes so I can't operate it to open the tailgate. If anyone has suggestions, I'd...
