How Negative phase sequence relay work
Bulbs? Fuses? Relay? Dimmer switch? Headlight switch?
Function that it controls won't work, but fuse and switch are good
If the fuel pump relay switch is bad then the fuel pump will not be turned on. Think of the relay like a light switch. If the switch has a bad connection then the light doesnt work.
A car relay is a type of switch of sorts in a vehicle. If the relay breaks, then whatever it was supposed to be used as a switch for won't work, much like if a fuse goes bad.
I have the same problem with my car horn steering wheel button. There is the problem with the horn relay switch. You need to open up the steering wheel and carefully determine the wires that are connected to the switch. In my vehicle's case, the relay switch is tucked in along with the airbag, which made it impossible for me to pull out the whole relay. I was hesitant to pull the relay out as it may render the airbag useless (as it may trigger accidental inflation), so I had to go with identifying the wires connected to the horn relay switch only. Once the wires were identified, I had to bypass the connection to the steering wheel relay switch and reroute the wires into a vacant spot on the dashboard. With a switch improvised, I can trigger the horn from where I mounted the switch, which is just below the steering wheel. Have a car electrician look at the problem and he may give some ideas on how to solve your horn problem. Good luck.
Most cars have a fuel pump relay switch located either under the hood in a fuse/relay box or on the firewall.
Allright with a voltimitter check your switchs so when you roll them up or down you have power to the switch if not its your door switch. if you do have power check if you have power to your motor. there is no relay switch theres only fuses.
its a relay in the dash or check ur switch

The 1996 GMC Yukon brake lights work by receiving power from the brake light relay switch. The brake light relay switch is connected to the brake pedal.
A signal from the ignition switch closes the contacts in the relay to allow current to flow to the starter.
