When ever its cold out and i start my car and put it in gear it starts to make a squeal noise like the bearings are blown but it also used to just do it when ever i had the heater or A/C on. when it does it to get the noise to go away i have to drop it in neutral and rev up to about 5500 then it goes away. So my question to you guys is what the hell is blown? Is it one of my bearings in my pulleys?
TIA

 

Could be pulley bearing but likely could just be you need to do new belts, or adjust your belts and put some anti-squeal goo on them.

It's most likely your belts. They stretch over time, and when the AC is on it puts extra drag on them causing them to slip and squeal.
