When the fuses, relays, dimmer switch, and the light switches have been changed, and the brake lights STILL fail to work means you "missed" something.
All lighting basics are simple:
When ALL components are good, the most common cause of failure of the brake lights to turn on is usually that the switch controlling the brake light circuit(s) IS NOT PROPERLY ADJUSTED.
Many possible causes... coolant level, thermostat, head gasket, water pump, fan not working
Replace the brushes in alternator. refer to the haynes manual on how to do it.
its the throttle position sensor
my 4cyl Toyota was doing the same, I changed the spark plugs and wires and it runs like new :)
check the brake fluid level in your master cylinder under the hood. The light comes on for two reasons, either the hand brake is on or your brake fluid level is low
What causes misfire 302, 304 and 306
One of the primary causes for this is a stretched timing belt. Even though the belt is a notched belt, they do stretch just enough to make the timing not conform to smog specs. I have had this happen, too, and found that a timing belt replacement solved the problem.
A little kid in the trunk with a hammer
Problem with the emissions system.
switches go bad especially if the windows were left down, takes awhile to affect the switches, get new one from parts van or junk yard
get a wheel alignment
does the speedometer effect the transmission
a/c kicks on
A failing alternator.
Yes and No. Circuit breakers, fuses, and switches all interrupt power flow when opened. Circuit breakers and fuses are current limiting devices that are designed to protect the wiring. They typically are tripped, or blown which automatically causes the circuit to be opened. Circuit breakers and fuses should not be used as switches. Switches are designed to only interrupt power flow.
Normally you will find three safety switches on a Huskee riding mower. There is one for the clutch/brake pedal. There is another one for the deck lever and the main one that causes problems under the seat.
If only one nipple has changed color, see your health care provider. If both have changed color, common causes are puberty and pregnancy.
Fluorescent lighting, Dimmer switches and bad grounding are often the cause.
It means that with thought toward the future, a government should not be changed for causes that aren't significant.
It can be a sticky caliper or you need to change brake pads.
Separation of the ethanol due to water in the gasoline.
Low fluid levels in engine.
It could be dirty fuel injectors.
