    My 05` Trailblazer has started to make a, powersteering noise. Sounds like fluid is low, but fluid is at proper level and no leaks seen. A friend suggested maybe idler pully?

    Also check the belt tension and you might try applying "Belt Dressing" to the belt sometimes this will cure the squeeling.

    My '05 Trailblazer was making a lot of noise when I first started it up. Like you I suspected the power steering pump, but it was not leaking and was full. I took it to a trusted shop and the first thing they did was replace the belt. That took care of some of the noise, but not all. Then they replaced the water pump. That got rid of most of the noise. There is still a little noise for about 1 minute after starting, which is apparently the fan clutch. Total cost was just over $400.

    I had to have the thermostat replaced about 6 months before the noise really got bad. I do not know if one affected the other. The thermostat went bad when we were traveling in California. Caused check engine lite to come on. Estimate for repair in Fullerton, CA at a Pep Boys was over $600. Actual cost of repair with an oil change in Surprise, AZ was less than $350.
