What`s making my CR-V A/C put out warm air? If your car`s air conditioning isn`t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system. What can cause an A/C system leak?
Malfunction Indicator Lamp: Also known as the Check Engine light, this Honda CR-V dashboard warning light looks like a yellow car engine, and it will come on when there`s a problem with the emissions control system. If a misfire in the engine is detected, this warning light will blink.
Honda dashboard warning light symbols and meanings

Red or amber lights are the most critical and indicate that there may be a problem with the vehicle. Blue or green lights are informational for the driver and are designed to let the driver know that a system, such as cruise control, is on or running.

If the radio displays and error (ERR) message, disconnect the black negative under hood battery cable for 1 to 3 minutes to reset the system). TURN THE RADIO BACK ON AND LOOK FOR THE WORD “CODE”. ENTER THE 5 DIGIT RADIO CODE. THE RADIO SHOULD COME BACK ON.
A second reason for the air conditioning unit to suddenly prefer blowing warm air may be because the compressor itself has gone bad. The main function of the compressor is to pressurize the contents in the refrigerant, and then pump it throughout the necessary components of the AC.
What is the MIL? A dashboard light that comes on when the vehicle`s computer finds a problem that could cause excess pollution. Often this means you should repair your vehicle to avoid costly damage in the future. If the light is blinking or flashing, have your vehicle serviced at once.
Just be sure to have your car inspected as soon as possible after the light turns on. Don`t neglect needed engine repair! If nothing seems out of the ordinary, you can continue driving the car. The cause could be anything from a faulty oxygen sensor to a bad MAF sensor.
The check engine light is usually the most serious and feared warning because of the kind of damage it can signal. This warning often indicates the potential for serious engine damage. When ignored, your vehicle could suffer from a blown head gasket or a seized engine.
There are two main types of dashboard warning lights: red and orange. A red warning light generally indicates a serious issue with your car. You should act quickly if your dashboard warning light is red – it could be an overheating engine, low engine oil pressure or a braking system problem.

Press and hold the audio system power button for 5 seconds. A menu may pop up and ask you if you want to reboot the system. If this doesn`t work, turn the vehicle off, open the driver door, close the driver door, and restart the vehicle.

A dying battery or even changing the battery will reset your radio the same way a power outage resets your home clocks. Usually, when your battery is changed, all you need to do to reset your Accord radio is to hold the power button for a few seconds until the radio starts up. No code is needed.
If your car is overheating, you should pull over at the first safe opportunity. Don`t touch the hood until you`ve given the vehicle at least 30 minutes to cool down. There are many reasons why a car would overheat, but issues with your coolant or your radiator are the most likely causes.
Overheating can be caused by a: Cooling system leak – This is the most common cause for a car to overheat. The radiator, hoses, water pump, head gasket, and thermostat housing are all components of the cooling system, and all can be susceptible to leaks.
One of the most common reasons your car AC is blowing hot air is because of a refrigerant issue—specifically, a loss of refrigerant. This loss of refrigerant can occur either due to a leak or because your car`s refrigerant levels are too low.
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.
The most common problem with the Honda CRV climate control is due to a leak or leaks in the AC compressor or condenser, resulting in a loss of the coolant. (The coolant is required to cool the air that is in the Honda CRV AC climate control system.)
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.
The most common reasons a Honda CR-V ac isn`t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor. You may not realize there`s a refrigerant leak until the air conditioner stops blowing cold.

What does the heat error warning mean?
ANSWER : When the CD player is in use and gives you the Heat Error warning, then the CD player is operating at too high of a temperature. Turn off the audio system, and give the CD player sufficient time to cool down before playing it again.

A/C and heat are not working properly. Car blows heat in summer and cool air in winter.
ANSWER : Common causes of no cabin heat include malfunctioning blend door(s) (part of the in-dash ventilation network), a faulty or stuck heater control valve, a plugged heater core, stuck open engine cooling thermostat, collapsed hoses, and low coolant level. The cost to resolve the problem depends on which of the foregoing faults is the cause. If you desire a diagnostic to determine exactly why there is no cabin heat, please request a non functioning cabin heater diagnostic and the responding mechanic will come right to your location and get this resolved for you promptly.

With regard to your air conditioning system, if merely re-charging the system restored normal operation but the a/c ceased to function after a month or so, that scenario typically suggests a leak. Some leaks are really cheap to repair, like if a couple o-rings need to be replaced in system piping but if the leak is at the compressor shaft seal, that repair is more costly. It is not expensive to find the leak and diagnose the system and once the leak is found the mechanic can let you know of the exact cost to repair the leak and re-charge the system. If you desire that service please request an a/c system diagnostic – suspected refrigerant leak and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you

Heat inside car stays warm for minute then blows cold until I turn heat off for a minute and try again.
ANSWER : Hi there. The engine always at operating temperature leads me to believe, the thermostat is not the cause, for no heat inside the vehicle. There are several possibilities for no heat inside, the heater control valve is malfunctioning, the heater core is restricted, the temperature blend door actuator is malfunctioning. Replacing components without diagnoses, can be expensive and time consuming without resolution. I recommend having your vehicle’s inoperative heater be diagnosed and repaired by a certified technician, such as one from YourMechanic.

My heat and air turns on without a problem but does not blow very hard (heat blows harder than air). Rattling noise.
ANSWER : The heater and the air conditioner both use the same blower motor. However, Nissan does have two separate fuses for the same unit. One of them can be blown. There are also resistors in the system that can fail. There are several electrical tests that can be done, but depending on the condition, it may be more practice to change the entire unit. Due to the age of your vehicle, and the Juke’s history of blower motor issues, it’s very likely a simple fuse issue. These can (for the most part) be visually inspected, and are cheap.

Car heat is cold until I add water and over heating with out telling me
ANSWER : Hello, thank you for writing in. There seems to be an issue that we need to take on first and foremost. This is the fact that you are having to add coolant to the system. This means the coolant is leaking either externally (onto the hot engine), or internally (being consumed with the air/fuel mixture). The best way to tell is to simply run the vehicle and watch for the leak. If the engine is consuming the coolant, you are likely seeing white smoke from the exhaust. This is most commonly resolved by replacing the head gasket. Common components to look for an external leak with are the thermostat and the water pump. Both would cause the symptoms you are explaining. Fore more help with the issue, contact our service department to schedule an appointment.

Vehicle at running temp, turn on heat, no heat – stomp on gas, there is heat – ??? 2004 Jeep Liberty
ANSWER : Hello – regarding your lack of heater function unless the engine is revved up a bit, you have a coolant flow issue. This could be caused by a worn water pump (engine might be running warmer than normal?), a partially blocked heater control valve (adjustment problem or failed heater control switch), or clogged cooling system that simply has poor flow. I would recommend an inspection of the heater & cooling system by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

What is the difference between engine oil warning light and another warning light just like that but with waves under the sign? 1996 Mitsubishi Galant
ANSWER : Hello- the warning light you mention is a " low coolant" indicator. Once the engine is cool – check your coolant reservoir and/or cooling system for proper fluid level. Since you seem to have lost fluid, I would recommend an inspection of the cooling system by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

My Accord gives out a "Charging system failure" warning. I drove home about 15 miles and then parked my car. After about 3 hours,
ANSWER : Hi there. On a new Honda Accord, the Charging System Failure warning light typically indicates a problem with the battery, alternator or other component inside the charging system of your vehicle. However, with less than 10,000 miles, this is most likely an electrical glitch or stored error code that was triggered. Since your car is "new", I would recommend contacting your Honda dealership first, to tell them about this warning light and ask them how they wish to handle this issue; as it should be covered under warranty. If they can’t help you, please set up a warning light inspection, and one of our mobile mechanics can come to your location and determine why this light came on.
