Hazard lights/horn My hazard lights and horn do not work. My divers side power window only works occasionally. Could these be related? When I push the horn pad. I do NOT hear a click under the hood. Any thoughts on where to start?

What exactly is wrong with it? Start with the basics. Check the fuse. I think on that model the horn and hazard lights were on the same fuse so test your hazard lights are working. Check the wiring and connections are clean and shiny at the horn sounder itself. If you know how to use a multimeter you can check for signal from the switch with a helper pushing the horn button.

the signals work off of the hazard flasher. the hazards are wired to constant power.if you run a fused wire from the hazard switch to the battery it all should work.
somehow the hazard power source got lost.check that there is not a blown fuse in the fuse box. a starter solenoid draws a good amount of current.they may have blown a small amp fuse looking for a power source.
patching into a fuse box for power is not high caliber work.

try pushing the hazard light switch again. what you have is the hazard lights in operation ( both sides indicators working) In normal indicator operation power from the flasher unit is directed to which ever side you select but by pressing the hazard light switch the indicator power lights up all lights.

Do you have power in and out of the hazard flasher ?

The hazard switch gets power from the horn fuse which is hot all the time, and from the turn signal fuse which is hot when the key switch is on. The turn signal switch gets power from the hazard switch and both use the same flasher.
So if the turn signals work but the hazard switch does not power the lights, and both fuses have power, I would say the problem is inside the hazard switch.

To buy it aftermarket yes you'll need the entire multi-function switch. However that year had a recall for just the hazard button in the switch, and can be purchased separately at a GM dealership. They lock in at the sides, remove upper steering wheel cover (hint you may want to remove the horn fuse or relay first, it can be activated while installing), use a very small slotted screwdriver and lightly pry the sides outwards. Pull the hazard button straight up. Apply lube to new button, and push down into groove until it locks. Reassemble the cover and horn fuse.

it sounds like the relay has gone for your hazard lights, when you press the button to turn them on, it will disconect the power to the main indicators hence wont work when hazards pused in, try locating either the hazard flasher unit, or the relay , have you checked the fuses?

Hazard warning lights and horn on a 2006 Ford KA don't work but indicators do

Check the hazard switch and the connector to hazard switch see if u have the power and earth to hazard switch if there is power and earth to switch then replace ur hazard switch its faulty but if there is no power and earth to switch then it has whirring problem

Also if you work it on and off about 50 times it cleans the contacts up and will work ok also.
