So i got this annoying screeching sound while im in drive and accelerating. I cant pin point because it only happens when im driving not just accelerating in place. If anyone could help me out that would be great.
Things that could help
-When it first started happening i turned on my ac while driving and it stopped immediately
-It happens only when reving the engine while driving but not when in park
-Also while rolling in neutral and accelerating
-Gets louder the higher i rev
-Most of the time it is screeching but some days it doesnt do it at all
-The ac pump squeaks when i turn the car on and the ac is on already
So im leaning towards the ac pump but i wanted to get some other points of view before buying parts.

Be sure to eliminate your belt as a cause. That's a lot cheaper than an AC compressor. Sounds like your compressor has a bad clutch or bearing, but it could possible be a bearing on another pulley.
I had a mystery screech before and finally figured out the location by removing the fan and shroud, then starting it up. You can do that for a couple of minutes without danger.
I got an AC compressor on ebay from ky_scrap for thirty bucks including shipping and it is working great three years later...
