Question about 2001 Mercury Sable

1 Answer

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 curing the head light issue. This problem is on my 2001 Mercury Sable.

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.

All exterior lights are on when engine is started and wont turn off until engine is off, could it be the switch itself?


Is this happening all the time or just at night? The car is equipped with automatic daytime running lights which automatically turns on the full lighting system at dusk and off at dawn or other lowered daylight situations. Do you have something on the dashboard covering the daytime running light sensor? Is the headlight switch turned to the off position?

2000 silverado The daytime running lights were not working but the headlights are now on all the time, functioning like running lights. I replaced the bulbs in the running lights but this made no...


check to see if something is blocking the daylight sensor on the dash. If it is not being blocked check to see if the relay for the automatic lights is stuck. If any of these issues are happening then the headlights would be on switching off the daytime running lights

Headlight


This is normal operation. The XL-7 has daytime running lights and automatic headlight controls. You can keep headlights off when starting by applying the handbrake. If / when the daylight sensor on the dash determines it is evening and turns on the headlights, they will come on regardless of the handbrake position; and obviously, if you want to move the car, you have to release the handbrake (and headlights come one).

Problem with Automatic Daytime Running Lights


Have you verified both high beams are in working order? DRL's are very funny about not working if one of the lights is burned out. Rememeber that DRL's are only high beams using 20% of the power so just because your normal lights work, it does not mean the high beams are working correctly.
