Why does my Lincoln LS V8 Blow cold air on one side and hot air on the other side
The heating system doesn't get heat until the car warms up and the thermostat opens.
Low coolant, failed thermostat, partially plugged heater core...............
most likely it's a bad thermostat, or your vents not working properly.

Could be a number of reasons for this condition. I would check the coolant level. A low coolant level could cause your heater to blow cold air when the engine is warm. Is the engine warm? If the engine is fluctuating temp it could be a faulty thermostat. Hope this helps.
This is often caused by air being trapped in the cooling system. Get a qualified mechanic to drain, flush and refill the radiator/cooling system.
There are a few possible reasonsÊthat an air would only blow cold when accelerating. The top two reasons are that the compressor fan might be malfunctioning or that the compression clutch isn't engaging.
It doesn't really blow it out it just warms the cold air.
I'm far from an expert but it sounds like you have a small leak or had one and the A/c just needs a recharge.
If it does blow just not cold air you should see if it needs to be recharged
An air conditioner blows out heat
