As the temperature drops, you’ll likely give your vehicle a few minutes to warm up. If the air from your vents doesn’t heat up within 5 minutes, it’s likely that you have an issue with your vehicle’s heater, your coolant or your engine’s water pump. Whatever the cause, a faulty heating system just won’t work in the winter.

Signs Your AC Is Going Out

If your car’s ac isn’t as cold as it usually is, this could mean that there is a problem with the air conditioning.

There are many things that can cause these problems. If mold or mildew builds up in the AC’s evaporator, it can stop air from reaching the vents. Cooling problems can be caused by loose hoses or a fried ventilation fan.

Your cars air conditioning relies on a part called the compressor. In the compressor there is a bearing that with time begins to wear out causing a squeaking/grinding sound. 

The compressor also uses a clutch, and when this is worn out it will cause a rattling sound. 

An old of dirty cabin filter can cause this smell. Bad smelling odors can also be caused by a mold build up.
