I changed the thermostat changed the heat sensor and changed water pump and the car still has no,heat unless it sits but as soon as you start driving the temperature Guage goes back down and car starts to get cold again please tell me what could this be
Hi there. Check the heater control valve on the heater hoses under the hood. The valve is controlled by vacuum. Check the vacuum lines and see if they have came off or split. With the engine at operating temperature, check the heater hoses before the valve and after the valve. The hoses should be the same temperature with the heater on. If the hoses after the valve are not as hot as the hoses before the valve, then the heater control valve is not working and needs replaced. If the valve is replaced and the heater still is cold, then check the thermostat switch for any loose contacts or damage. If you need further assistance with your heater being cold, then seek out a professional, such as one from Your Mechanic, to help you.

Check the Coolant and Water Pump
First, check your coolant level to be sure there is enough liquid in there to even get to your heater core. If your radiator is very low on coolant, you`ll get no heat. If your levels are okay, you either have a bad water pump or a thermostat that isn`t opening.
Low coolant may prevent any from circulating through the heater core, as can an air bubble in the system. Make sure the system is full and free from air by filling it with the engine running and the heater controls set to maximum heat.
The most common reasons a Chevrolet Camaro heater isn`t working are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor. Search our network of RepairPal Certified shops near you to speak with a technician about your issue. Oops!
You May Have Low Coolant
Your engine accumulates a lot of heat when working, and coolant helps to collect this generated heat by transporting it to your vehicle`s radiator for cooling. If the coolant is low and your heater is on, you may notice that your car heater only works when driving.
A malfunctioning thermostat can make your heater or air conditioner unable to turn on. In most cases, this indicates the wiring has failed. Normally, electrical wires transmit messages from the thermostat to the HVAC unit, such as telling it when to turn on and what temperature to make your house feel.
A faulty or broken thermostat is the most common cause of your car`s failing heat. Stuck open or stuck closed, the part can not only cause issues with your heat but also with your engine`s cooling system.
The average cost for a Chevrolet Camaro Heater Core Replacement is between $908 and $1,139. Labor costs are estimated between $747 and $942 while parts are priced between $161 and $197.
The heater core in your car works like a radiator to move hot air through your car`s vents. Damage to your heater core will have some telltale signs. Excessive condensation on the inside of your windows tends to indicate a leak. Your heater will also only give off lukewarm or cold air if your core has a problem.
Start your car`s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
To do so, locate your home`s thermostat and tape an accurate thermometer on the wall next to it. Wait 15 minutes and check the temperature reading on both devices. If your readings are three or fewer degrees apart, you should be good to go.
Heater Core Gurgling Noise
Can you hear a gurgling noise coming from the heater core? This usually means that there is air trapped in the coolant that circulates through the core. This can happen for a number of reasons, including a blown head gasket or a leak developing in the heater control valve.
There are multiple reasons a car`s heater core could not be working properly. One reason could be due to clogging, as the coolant could become contaminated if it`s not regularly flushed out. Another reason for a bad heater core could be because of a leak somewhere in the system.
To get there as quickly as possible, the thermostat closes to keep the coolant inside the engine from travelling through the entire cooling system. Once the engine warms up enough, the thermostat opens. That now-warm coolant circulates into the heater core to keep you toasty.
You Have Cold Air Blowing Out The Vents When The Heat Is On Because of a Dirty Air Filter. Hiding in the filter of your heating system is dirt and debris. If you aren`t cleaning it regularly, this will accumulate over time, leading to problems with your heating system`s efficiency.
Water by itself can`t do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle`s engine. Plus, it doesn`t absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
When there is a leak in the cooling system, it allows air into the system causing an airlock. The airlock blocks the coolant from circulating through the system, potentially causing the vehicle to overheat.
The warmth from the engine goes from the radiator to the heater core, which basically acts as a heat exchanger. It allows coolant to flow through, and this flow of coolant is regulated by the heater control valve. As the engine`s heat is carried by coolant into the heater core, the device starts to get warm.
Yes, many air conditioners can be used for heating as well as cooling, with the inclusion of a reversing valve. The energy flow can be reversed which transforms the air conditioner into a heater. This is called reverse-cycle technology.
How Frequently Does a Chevrolet Camaro require maintenance? Overall – the Chevrolet Camaro has yearly car maintenance costs total to $585 .
Fixing a leaking heater core will always be much easier than replacing one. Since it is only a small leak in the heater core, we recommend simply sealing that leak and leaving your heater core in place. You can do this by simply by adding BlueDevil Pour-N-Go to your vehicle`s radiator when your vehicle is cold.
One of the most common issues with a heating system not functioning is dirty air filters. If your air filters are extremely dirty, then the airflow can be blocked. Check for clean air filters, vents, and registers. Make sure there are no rugs or furniture blocking vents or registers as well.
Low Coolant Level
The coolant (usually a mixture of water and antifreeze) in your engine doesn`t just work to keep the engine from overheating: It`s also the source of heat supporting the heating system. If there isn`t enough coolant in your system, the heater core will blow cold air into your car.
Adding coolant does nothing to address the problem that caused your engine to overheat in the first place, but it often allows you to drive safely to the nearest repair station. “A professional will need to inspect your car`s cooling system,” says Reina. While driving, keep an eye on the temperature gauge.
