Relay Information

When an electrical component in your home stops working, the first thing you'd probably do is check the fuse box. The same strategy holds true for your vehicle. That is, when electronically controlled components are not working, you should inspect all fuses. If they're okay, it is time for a check of the relay to which the fuse supplies power to trigger use of the component. Control relays act like switches that utilize an electrical signal to become activated, after which they will supply an electrical charge to components and accessories ranging from the fuel pump to the headlights. An experienced auto technician may tell if a relay is defective simply by feeling for it to click into operation.

Of course, having fuses and relays checked and replaced on a regular basis is a great way to prevent electrical failure in the first place. At BAY STAR AUTO CARE, our ASE-certified technicians can provide the regularly scheduled maintenance that will keep your car in good working order and stop major failures before they happen. This sort of preventative care improves your car's lifespan, which saves you money in the long run. And don't forget that we perform smog checks!

HINT: Because relays turn off and on thousands of times and may be subjected to a wide range of temperatures, they are prone to failure at some point.
