Steering Noise Problems of Chevrolet Blazer

On several occasions, in the mornings when Blazer is cold and the weather is cold, I have heard a rumbling noise when I turn the steering wheel to the left. Once the vehicle is warmed up the noise goes away. The first day I took the the shop, the repair man said it was unusual but he did hear the noise and said it sounded like it was in the steering shaft. He made an appointment for the following day. While checking the vehicle they did not hear the noise. A week later, it was extremely cold and snowing, the noise returned I stopped on my way home from work and another mechanic heard the noise, he felt it was in the power steering system and made an appointment for the following day. On this appointment, they could hear the noise but " it was not loud enough to pinpoint where it was coming from" so they returned the vehicle to me. He made arrangements to keep the vehicle over night and give me a rental car. I told them that they should check it first thing in the morning as soon as they got there. Which they did not do. They waited until I returned later in the morning to test the vehicle and it had warmed up outside and could not be heard. They claim they have checked the power steering system and everything is fine. I am afraid that something may happen to the steering wheel or inside the steering system while driving and I will not be able to steer the vehicle or could be in an accident and possible injure myself or someone else.
