My 2001 Chevy Tahoe has lost its power steering. I checked the fluid and it is at the correct level. All belts seem to be intact and in good working order.
This happened suddenly last night - I think when I was taking a hard left turn.
Any ideas what else I can check to determine what is at fault? I don't have a service manual. Is there any relay or electrical component to the power steering?
Release the belt tension and see if you can move the PS pump pulley in/out. Could be a broken pump drive shaft. Seen that more than once.
