I can pretty guarantee you it is your altrnator belt.. By turning on your headlights, it creates more load on the alternator, which in turn makes the belt work harder. To confirm, you can try some silicone spray on the belt. The noise should change or disappear. This happens a lot in winter when dirt gets on the belts.
Usually that will solve it. If not, you may have to get the belt changed.
Good luck,

Dan

The belt is slipping or the compressor and/or clutch is bad.
If the compressor won't turn freely with the engine off, it may be locked up which will make the belt screech.

Check fuses to see if there are busted ones. Then check heater plugs if good. Heater relay included in check. Engine wont fire if the air inside the chamber is cold. Then check fan belts for wear, replace if necessary.

hi as the timing belt is toothed it would not slip however it may be loose and in need of renew? as you do not mention milage ie period the belt is due for replacement ? the screech if this above is problem? would/could be the belt slip on the adjuster bearing which should also be renewed with belt i would first check out the alternator/p/steer belt as the loading of belt if slack/worne when starting from cold will give screech as it starts to overcome load of alter and especially p/steer oil pump then noise ceases as engine warms?? if you drop this belt off bfore you first start from cold ? would give an indication of which belt req's attention ? ps! as for age of car/milage? would not ignore the recommended milage for timing belt renewal ? hope this helps you diagnose problem ?

Screeching noise when I turn on my air conditioner or heater


It may just need to be adjusted (it sounds like it's too loose). If the belt isn't cracked or frayed, you should just have it tightened up a bit . If there are signs it is worn (cracked frayed) replace it.
