Simplest answer is that the refrigerant (freon) may have leaked out. Also could be: loose wire - faulty A/C relay or fuse - bad compresser - you need to have it looked at and the possibilities narrowed down.
One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.
There are several reasons: 1. There is no air so you would suffocate. 2. It is extremely cold on Mars. 3. There is no water to drink. 4. There is no food on Mars.
Could be many reasons but the most common would be low on freon due to a leak in the system.
There are many reasons that the cars heating system may alternate between blowing hot and cold air. Some common causes of this include the heater core and air pockets in the coolant.
Cold air is heavier than warm air.
There are a few reasons why a central air unit is not blowing cold air. The coils may be dirty, the unit may need freon, or the thermostat could be broken.
Probably from a lot of reasons but mostly from a busted air compressor, faulty wiring, no more freon, or a broken fuse.
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.
could be many reasons i.e. thermostat, air mix door, temp adj, but 1st thing i would look for is to check the coolant level in the radiator. If it's low, cold air is what you are going to get.
Rabbits can get sick from their environment but are more than likely to get sick from other reasons than the basement being cold. Drafts, dampness and poor air circulation would be more likely causes. Also if a rabbit is already carrying a cold germ it may be exacerbated by any of these conditions where if in a normal environment with good air circulation they would not exhibit any cold symptoms.
There are multiple reasons why this might be, and no way to narrow it down without proper diagnosis.
It would be a cold-front
