2011 Honda Crv Ac Relay Location (2024)

FAQs

Where is AC relay switch located? ›

You can find the relay located in the outdoor unit of your HVAC system. Relays have three wires connected to them: Input wire from the control board. Power feed wire to the ac compressor clutch.

Irregular Cooling: A sure sign to relay failure is uneven cooling. Once the relay starts to fail, it will provide relatively weak, irregular power to the AC compressor, and the compressor will work intermittently as long as it receives power. The result is uneven cooling.

One surefire sign that the relay switch is faulty is that the compressor does not turn on. Typically, you will hear the compressor turn on when the air conditioner turns on. This is typically a series of clicks as the clutch turns on and engages, followed by the low hum of the blower motor.

Yes, a bad relay in your AC system can indeed cause the entire system to stop working. Relays play a crucial role in controlling the flow of electricity in your AC unit. They enable the thermostat to communicate with the high-power components of the system such as the compressor, condenser fan motor, and blower fan.

The A/C relay, which is also known as the A/C compressor clutch relay and the A/C compressor relay, is in charge of engaging the electromagnetic compressor clutch. The A/C relay can usually be found in the vehicle's fuse box.

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.

Air conditioners use fuses to protect the condenser from excessive amperage, and fuses can only handle a limited amperage based on the maximum rated amount. If more amperage tries to go through, the fuse blows to prevent overheating. Usually, AC units use “TR”-type fuses to ensure safe operation.

How Much Does a Replacement A/C Compressor Relay Cost? Depending on the model of your vehicle's sources, the cost of a replacement A/C compressor relay ranges from $10 to 150.

Testing Switch Pin Continuity

The switch pins on a Normally Open (NO) circuit should have no continuity when not energized. Use a multimeter on the ohms setting to measure resistance between the switch pins. Any resistance indicates the pins are stuck closed, signaling a faulty relay.

Can a blown fuse stop AC from blowing cold air? ›

It's also possible that there is a very simple reason your car air conditioning is not cold, and that is electrical. Some of your A/C system's parts, including your compressor, are electrical. And something as simple as a blown fuse can cause it to stop working.

In some cases, your AC system may still function, but not at peak performance. Bad air conditioning relays can come with their own set of symptoms. As a result, you might run into one or more of the following issues: AC compressor does not start.

If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won't turn over - no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.

Something Is Causing a "Parasitic Draw."

These things shouldn't have a major impact on your battery. However, interior lights, door lights, or even bad relays can drain a car battery when it's off.

Starting relay position

The fuse box (also called the power box), the instrument panel under the fuse panel, or the right fender are all possible locations. In most cars, it will be under the hood, in a large box with a black lid. This is where car fuses and relays are installed.

Typically, you can find the switch for the indoor unit near your system's furnace or air handler. You can find the switch for the outdoor unit next to the outdoor unit, usually in a metal box on the exterior of your home.

Your exact repair costs will depend on your car and location, but the average cost for an AC compressor relay replacement is $66. We can break that price down into $23 for replacement parts and $43 for the technician's labor costs.

A bad blower motor relay may result in your HVAC system's fan not turning on. A bad compressor relay, on the other hand, may result in your AC system not turning on. You may still hear the fan turn on in the latter scenario, but you'll likely feel room-temperature air rather than cool air coming out the vents.
