2004 chevy avalanche z71 4x4. 
Problem- when turning to only right at slow speeds(parking spot etc) I have no power steering.  Steering to the left I have no problems.  Any ideas?

If your power steering is normal to the left and it goes away to the right, I think this indicates that the fluid pressure supply from the p/s pump is good and you may have a mechanical failure or blockage of fluid flow in the assist side of the steering gear. you will most likely need to disassemble the steering gear to look for debris in the fluid return passages or replace the steering gear altogether to correct this condition.

An internal company bulletin shows that the Chevrolet Avalanche, Tahoe, Suburban and Silverado Classic; GMC Sierra Classic and Yukon; Cadillac Escalade; and Hummer H2 are at risk for the steering lock-ups. The problems affect various model years dating back to 1999.

Quote
GM's bulletin says the condition, which stems from a lack of pressure in the power steering system, can be aggravated by worn tires, low tire pressure and tires larger than stock size. For nondiesel engines, GM has told dealers that adding a pressure valve may help fix the problem. Vehicles that run on diesel engines cannot be fixed.

Quote
General Motors Corp. has told its technicians the problem occurs when customers apply the brakes and turn the wheel at the same time, which easily can happen as drivers try to park.


Quote
In November, however, a Wisconsin jury awarded $120,000 to a plumber who was often unable to steer his GMC pickup truck and was denied a refund or new vehicle after he complained. GM must pay an additional $259,000 in attorney's fees by Tuesday.
