Squeeling noise- VIDEO

I've had this noise for a couple weeks.



I've been busy with work and I didn't have time to work on it myself so I dropped it at a supposedly reputable shop (Cambridge Auto in San Antonio). They said it was the ac pulley tensioner and replaced it. Did absolutely nothing to fix this noise.

Any thoughts on what else I should look at?

The belts look good. Almost look new.

I could be wrong but if memory serves me correct this is the noise my bad tensioner pulleys made.

My car does the same thing and I've replaced all tensioners and pulleys except for crankshaft pulley, power steering. Also being that the alternator and AC compressor run on the belt do those units count too? I'm also assuming you can't just replace the pulley on those parts.

I'm suspecting its my power steering pump and its pulley. I've been dealing with reservoir leaking for quite some time. I should be getting parts to replace today from pelican parts
