What would not allow my heater not to give me heat.the temp. is reading in the ok range-not running hot,but no heat coming out of the heater.


Is it a GM prouduct? If so it is a bad heat sensor and/or activaters that controls the interior heat and cooling..a common problem with GM ..need to have them checked out...can be an easy fix like defective operating arm or an expensive one if the problem is the door inside the heat/cooling compartment..hope this helps..good luck.

When I put the heat on in my car it blows warm air for a few seconds then goes to blowing out cold air.


The lack of heat in the car has little to do with the car's cooling system, other than the hot coolant is the heat source. 95% of all "no-heat" issues are related to heater controls and/or the heater core itself. Since you get some heat, and then it goes away, this indicates a probable vacuum leak in the heater controls. When you select heat, vacuum is directed to a vacuum motor. This motor operates a vacuum actuator that moves a linkage that moves a door inside the heater box to direct the interior air through the heater core. If this actuator has a leak, it will activate, then as the vacuum leaks off, deactivate. You probably need to have a part replaced in the heater actuator mechanism.

Heater not working blows but no heat


Oh no! What do you do when your car heater not working? How do you figure out why there's no heat in car? What if you have no heater in car? Before you start trying to figure out how to fix car heater yourself, you should know a little about how your car's heating system operates. That will help you to figure out your car heater problem and why your heater isn't working properly or even at all! So, let's talk about how your heating system functions and then about some of the more obvious reasons that it you may be getting no heat from car heater. In order to heat up the inside of your car, the heating system uses some of the excess heat produced from your engine. Actually the engine produces so much heat that if you didn't have a way to release it (the heating/cooling system in your car) it could harm and even destroy the engine! That is why the heating/cooling system is set up to remove some of the heat and keep your car running smoothly.

The heat in our 1998 continetal doesn't work. We replaced our thermostat. Still on heat. The a/c works fine. The vehicle run fine without any sign of over heating. We can't undrestand why the car's heating...


Two possible reasons, one is that your heat control valve that directs hot coolant to the heater core may be stuck or blocked. Two, you may have an airlock in the heater core that prevents water getting in to the heater core. You need to let the air out by loosening the upper most hose that feeds the heater core.

The interior fan for heat and ac will not run


Your car's heater is a life saver in cold weather. Before attempting to repair your car?s heater, you should understand how your car?s heater system works. First, on this page is an explanation of how your car?s heater system functions, further down the page are some pointers on heater system trouble-shooting. To warm the passenger cabin of your car, your car?s heating system makes use of excess heat from the engine?s internal combustion process. A car?s engine, in fact, when in operation produces so much excess heat that if the excess heat is not removed, it would destroy the engine. It is your car?s cooling system that removes that dangerous excess heat. Some of an engine?s excess heat is released through the exhaust. Most of an engine?s excess heat is absorbed by a circulating liquid coolant, which is a mix of water and antifreeze. The heated liquid coolant is carried from the engine through hoses to the radiator, which transfers the heat from the coolant to the outside air. That heat transfer lowers the temperature of the liquid coolant, which is then circulated back to the engine to absorb excess heat again. Whereas the radiator is located at your car?s front grill, the unit that transfers heat to the passenger cabin is located inside the dashboard. This unit is something of a mini-radiator and is referred to as the heater core. Heated liquid coolant circulates through tubes in the heater core and a heater fan blowing across those tubes, as well as through little fins encasing the tubes, directs warm air through heating vents into your car?s passenger cabin. Because your car?s heating system works off of its cooling system, heating system malfunctions are often caused by problems in the cooling system.

The heater core in your car is similar to the radiator in the front of your car; in fact it looks like a small radiator. The difference is the heater is mounted inside the car and air is blown through the fins of the core. The heater hosestransfer engine coolant from the engine to the heater core, this allows the heat from the engine coolant to be utilized and warm the passenger compartment.
