More than liekly it isn't your switch. You have a ambient light sensor (sometimes called a photocell or amplifier) that detects how dark or light outside which in turn turns the lights on or off. this sensor is located under that "grille" just below the windshield. Sometimes water can stand in there and cause that sensor to go faulty. I say it's that in most cases because a switch, if it goes in most cases it just goes period. It is a fairly common problem also. Hope this helps....

SOURCE: odeometer and clock lights

Just replaced bulb on my 2002 Accord EX. Simple to do.
1. Lift up the trim piece around clock; just slide a putty knife under and lift.
2. Take out assembly and look on underside for small gray bulb base ( about 3/16 dia.). It helps if you have the new one to compare.
3. Use small blade screwdriver in slot and rotate counterclockwise to remove. You may have to shake it to get out.
4. Examine the new bulb to find the slots that DO NOT have wires. Put bulb into socket and rotate clockwise with screwdriver in proper slot.
That's it; you now are there.

SOURCE: 2003 Mercury Sable, Driver's side remote keyless entry keypad not functioning

Doubt its a fuse. Most likely the key pad has failed and needs to be replaced. On the bright side this is a good problem to have and you have a very reliable car.

SOURCE: Troubleshooting code PO442 check engine light on

The code PO442 is a small leak somewhere in the evaporative emissions control system, the best way to find that is to take to a shop that does smoke tests for emissions.
As far as the nozzle, try changing the position of it the next time you get gas.

Dash lights won't work


You may have a fuse or a circuit breaker failed.
Check fuses and circuit breakers both under the dashboard and also under the hood of the car to see if you can find a defective one.
If you have no luck, you may need to see and electrical expert mechanic.
God bless your efforts.

2002 mercury sable auto head lights don't work have to turn on manuall


If that was my car, I would go to the wiring diagrams
I buy for all my vehicles when I first get them

From there you make some choices as to how the system
works & where to start your testing or in an extremely rare
case replace something

I simply can't tell you if that switch you turn is bad or it
is good & it's output goes to a module,need to see the
system on paper

The headlights do not activate automatically, in the auto mode, at night or with minimal daylight. However the running lights will activate in the auto mode. A new dash light switch was installed without...


The light sensor to control the automatic headlamps is located on the dashboard. This sensor is suppose to activate running and headlamps. I would suspect the problem is a relay to operate the headlamps if the car uses a seperate relay in the automatic mode. I'm assuming the headlamps work in manual on/off. FYI... The auto mode does not control the fog lamps.
