Need help diagnosing power steering pump issue

[TooManyRaccoons]

Hey folks, I have a 2003 Baja, haven't had it for all that long so I'm not familiar with everything yet but recently I took it into the shop to have the timing belt and clutch replaced while I was out of town and when i got it back, it was making this weird squealing sound.

Now, i have done a bit of research, seems like its something to do with the power steering pump. The sound is sort of like a squeal that happens when I turn the wheel. The pitch increases as rpm increases and the volume changes the further I turn the wheel.

Some info that may or way not matter: the car was sitting for ~2 weeks while I was out of town. I never had any evidence of power steering issues before this. I did check the power steering fluid reservoir and it seems fine, slightly below the max fill line.

Any info would be a great help, thanks!
