How to test and diagnos a defective relay on Chevrolet Cobalt?

Several electrical accessories in a vehicle, such as the fuel injection system, horns, starter, and fog lamps, use relays to transmit the electrical signal to the component. Relays have a control circuit and a power circuit, and if a relay is defective, the corresponding component will not operate properly. Most relays are located in the engine compartment fuse/relay box, with some specialized relays found above the interior fuse box in the console. To test a relay, it can be removed and checked for continuity using an ohmmeter. The terminals of ISO relays, commonly used in these vehicles, are numbered to indicate their circuit connections and functions. Terminal 85 and 86 are typically the control circuit, with terminal 30 connected to the battery voltage source and terminal 87 connected to the component being powered. If the relay contains a diode or resistor, specific polarity and resistance values should be observed. If the relay fails any of the tests, it should be replaced.

Chevrolet Cobalt Relay

The main function of the Chevrolet Cobalt Relay is to act as an electric gatekeeper to safely allow a low power signal to control higher draw devices in the car's climate system. The Relay opens or closes its contacts to turn on or off the power to the condenser fan, blower motor, or other temperature critical components. Thus, a failed one can leave you without cooling or heat, although the main components are still fine. The early Chevrolet models utilized an electromechanical Relay that relies on an internal electromagnet. Later editions of Cobalt may use a solid state Relay that switches with semiconductors instead of moving parts, giving faster response and less wear. Another type, the magnetic latching Relay, locks down with just a single pulse, so when power drops suddenly, the Chevrolet Cobalt climate circuit setting remains intact rather than resetting after power drop. The Relay should be tested first irrespective of the design, as it can save time and money. Replacing larger components while the little switch goes untested often accomplishes nothing.

Each OEM Chevrolet Cobalt Relay we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
