The computer that contors the AC is not responding. Lucky for you this part is no longer in circulation. Take it toa professional electricle repair shop and have them by pass the computer that controlls theACcompletly. In other words wire dirctly to the dash controls. I just had this process done to my 95 olds after repacing my compressor twice in less that 3 years andhaving the system rebuilt behind the dash board becauseof leaks due to the system being overfilled by previous shops that had preformed work on my ac system because it would not blow cold air. What a head ache and pain in the wallet. email@example.com
Blower motor working? Could be bad vacuum motor or connection could be plugged evaporator
Compressor not running?Heater control in heat position?
There is a short somewhere. Probably the condenser fan motor or the compressor. Time to have it checked out by a competent, trusted techenician.
There are heater doors on the heat blower box that direct the path of the heat. Apparently the heater door to the floor vents is stuck closed.
Air still in the vents or freshly-shut coils still contain heat for a short amount of time after turning off the power. Also, it could take a short amount of time for the fans blowing the air to slow down, even after cutting power.
I have a 99 Ford F250 super duty. When I turn on the fan to the heater and AC I can hear air moving in to the vents. No air moves out of the vent on any setting. It is like all vents are closed. what could be the problem. I have replaced the switch. I check the blower motor.
There are several different types of heat vents. Vents come in metals such as aluminum, copper, stainless steel, bronze, and brass.
Could be,blown fuse, bad blower motor, bad switch, bad resistor,
Car not blowing air or heat
heat and a/c barley blowing in back?
Having the ceiling fan blow upwards will circulate the heat through the entire room.
perhaps because the engine running heats coolant that cycles through the heater core and has air blowing across the aluminum to exchange the heat into the air that is forced through the vents
Its your Heater core if it smells like a syrupy sweet smell if not then its your thermostat
If that vehicle has a cabin filter, the filter may be plugged up and in need of changing.
The inside blower keep operating until it has used all of the cooling your compressor has done. it is the same on central heating. The fan keeps blowing until the heat changer is cooled.
What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
There is no heater matrix for the back air vents, only and evaporator for the A/C. My suburban always blowed cold until I added an extra rear heater matrix.
In a car the heat usually comes from engine "waste heat". You just need to be running the engine. The compressor is part of the air conditioner, which is used for cooling not heating.
Vents in the volcano are passage ways for the magma, steam, and heat to escape the earth.
The temperature blend door may be stuck in the heat position. In my Caravan, the fan belt was broken when this happened.
there are coils in the back of the fridge with a fan blowing on it when the compressor gets to hot it takes a break and then the fan cools it down mostly stays off for a few hours..
It appears your blower motor is not working correctly on your 1980 Cadillac Coupe Deville. The vents are for both AC and heat. You may also be losing vacuum pressure. If you cannot find the source, your mechanic can help you do so.
A duct has come apart under the home?
what i am assuming is being talked about is that when you go to turn on the heat in a Seville, heat will only be produced out of one side of vents. there are a number of valves in a Seville which control wether the air that is coming out of the vents in hot or cold. in a Seville there are a pair of these valves one for the passenger side air, and one for the driver side air. the reason why only one side of the car is blowing hot air is because one of these valves has gotten stuck in the "cold air" position and needs to be replaced. the same thing happened on my car but the drivers side was the one not blowing heat.
