Usually cars that blow cold on one side of the dash and warm on the other side, are typically equipped with a dual zone climate control system. Dual zone systems allow the driver and front passenger to adjust respective temperatures to their comfort levels.
Either the engine is not getting to operating temperature, which means the thermostat needs to be changed out, or it is low on coolant, or the cooling system needs to be purged from air pockets, or the climate control blend door is not working. Check to see if the heater hoses are getting hot.
the problem is the heater bend doors. this part controls all direction of heat or air. there is one for each side of the car. replacing takes about 30 min.
The most common reasons a Ford F-150 heater isn`t working are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor.
A car A/C blowing hot air is often the result of a refrigerant leak. Refrigerant is a liquid that circulates through your car`s A/C system, expanding and contracting as it removes heat and humidity from the cabin. None of the other A/C components will function correctly without proper refrigerant levels.
If your coolant level is a-okay, but your car heater is blowing cold air and your engine is overheating, then you have a clog in your cooling system. Conversely, if your engine temperatures are unrealistically low after a drive, your thermostat is likely the culprit.
If you find your furnace blowing cold air, you may have a dirty or clogged air filter. To make sure, remove the air filter and inspect it. If it`s clogged with dust, clean it with compressed air or wash it in warm water with mild soap or just buy a new one.
The most common cause of a furnace that blows cold and warm air intermittently is a thermostat fan setting that is set to ON. Furnaces run in heating cycles and only produce hot air for short bursts of time. When your fan setting on your thermostat is set to AUTO, the fan only blows when the furnace is heating the air.
Faulty heater cores and low or contaminated coolant levels often come hand in hand, and both issues may lead to your engine overheating and your heater not blowing hot air.
Troubleshooting Tips For Furnaces Not Blowing Hot Air
Make sure your thermostat has not been set to a lower setting by someone else. Check your thermostat`s batteries and replace any that are exhausted or defective. Clean all of the parts of your furnace, especially the ones that are susceptible to dust and dirt.
Here are some of the most common causes of why air doesn`t flow out of your vehicle`s vents: Your air intake is clogged, meaning that air isn`t getting in from the outside at all or isn`t circulating properly. There is a blown fuse in the ventilation system. Electrical issues such as a bad relay.
A malfunctioning thermostat, no matter what kind it is, can cause a number of problems for your heater, ultimately hurting its effectiveness and efficiency. For instance, a thermostat sending incorrect signals—or no signals at all—can result in a heater that won`t even start up.
Warm air may blow from your vents if there is a big enough leak in your home`s ductwork. The ducts within your home deliver cool air throughout, but if there is a leak, warm air can be mixed into the already cooled air, producing warmer than normal air blowing from your vents.
Low refrigerant pressure can cause the left side to blow warmer air than the right side, but in no case will low pressure cause the air on one side to be warmer than the outside air. Your problem is that the left side heater is stuck on.
Low refrigerant pressure can cause the left side to blow warmer air than the right side, but in no case will low pressure cause the air on one side to be warmer than the outside air. Your problem is that the left side heater is stuck on.
If your air conditioner is blowing out warm air, your unit`s refrigerant levels might be low. This usually indicates a refrigerant leak in your system! If that`s the case, your air conditioner will continue to run and blow out warm air, trying to reach the temperature you set on your thermostat.
