This could be caused by dirty or over-aged power steering fluid, it's not flowing enough when the engine is cold (so the fluid) lack of enough fluid flowing through power steering pump can cause the power steering pump to start whining. Change the fluid and you should be good. Hope it helps and please don't forget to rate the answer if it was helpful, it helps me, thanks!

problem could be a bad water pump.

If the engine temprature does not reach the normal level as it used to, it may be the coolant thermostat.

Iif it does, it could be air diverter gates not working properly, cold air blowing at a a light could point to that. The diverter gates are located under the dash.

It also coul be the valuve that controls the water to the heater core, but unlikely cause of the cold air at a light.

nothing try back flushing heater core, they clog up due to litle water preasure,you might want to flush cooling system if you already havent, hope this hleps.

Put key in ignition. Hold down one of the key buttons and hold it down while you turn the ignition on. Door locks should pop up and down. Then release button and remove key.
