The heater in my excel blows cold air only . The dimist still works just no heat what should i look for?


There are several things that you can do about a heater blowing cold air, but if you keep running into problems then it might just be time to call in a heating repair company. If need be, here is a useful article on: HVAC installation cost, and how to get a fair price. How serious of an issue this is depends greatly on where you live. If you live in the north (Bozeman, MT, etc), then I'd recommend you have your furnace inspected annually to ensure that it is working properly. I'd also recommend that you install a backup means of heat...just in case. ASM has over 25 years of heating and air conditioning experience. If you have questions about a heater blowing cold air or any other HVAC related topic, try the ASM Air Conditioning and Heating Blog or if something your contractor is telling you seems expensive or doesn't sound quite right, consider using our Online Air Conditioning Consultation Service.

No heat/airconditioning in Lexus RX 330


The warning lights are probably not related to no heat, unless the engine is low on coolant.
It sounds like a problem with the blend doors under the dash, or the main controller. You may need a shop manual to diagnose it.

I am in saudiarab i have crown victoria 97 model it is working good but i have problum in air condition system when i run my car its running good no problum but when i start my air condition it is heating...


The air conditioning condenser creates a lot of heat when the a/c is on. The cooling fan is supposed to run the whole time the a/c is on to keep it cool. If the fan isn't on, the radiator will absorb this heat and cause your car to over heat. You should also check your coolant level. So, it sounds to me like your cooling fan isn't working.

Heat does not come out passenger side of the car but comes out drivers side


There is a blend door problem.

---
prev.gif next.gif HEATING AND AIR CONDITIONING Refer to Section 1 for discharging and charging of the air conditioning system. The heating system provides heating, ventilation and defrosting for the windshield and side windows. The heater core is a heat exchanger supplied with coolant from the engine cooling system. Temperature is controlled by the temperature valve which moves an air door that directs air flow through the heater core for more heat or bypasses the heater core for less heat. Vacuum actuators control the mode doors which direct air flow to the outlet ducts. The mode selector on the control panel directs engine vacuum to the actuators. The position of the mode doors determines whether air flows from the floor, panel, defrost or panel and defrost ducts (bi-level mode).

Not getting any heat from my Automatic air conditioning and heating heating system


Could be a couple of things. The first thing that I would check would be the coolant level in the radiator, if that is low it can cause the heater not to blow hot air. The second thing I would find out is if the control to change from cold to hot is actually working? ( if it is a manual slider then the cable might have come off of the control behind the dash...if it is digital then there may be a wire off?) The third thing it might be is that your Heater Core went bad and will need to replaced. As I said above, I would check the coolant level first and go from there. Hope it helps!
