On the left side, back in the "luggage" area, behind the wall carpeting, there are two junctions of wires. Check to see whether or not you put something in the rear that pulled any of these wires loose. If not, check your reverse switch on the reverse linkage. Your repair manual will show you where it is on each car, IF you have a manual. If you don't, ask a Ford mechanic or BUY a manual. They're only about $15. A mechanic will cost you anywhere from $75 - $100 just to look at it and diagnose.
Had the same problem with my GL. What I've heard is the back up blade in the shifting fork slips or falls out of line causing no contact when you shift into reverse. They have to replace reconnect thru transmission. 5 years without backup lights.
Check the backup light switch.
If you have replaced the bulbs and your getting that warning still, I'd say pull your battery terminals for 2 minutes then put them back on so the PCM/Computer can reset. That should fix the issue.
Check the fuses Check the backup switch Check the wiring - make sure that there is good contact.
check the ground for the lights
If the night running lights have failed the bulbs should be checked. Find the bulb housings and remove the parts. After the bulbs are replaced check the lights.
I would check the wires just behind the light. I had the same problem and the wires were broken a little just wiggle them as the lights are on.
Try checking the neutral safety switch. This switch is the one in automatic transmissions that makes the backup lights "flip" on when going from park to drive as you go through the gears. When my neutral safety switch shorted my backup lights stayed on constantly.
Check bulbs and switch
Did you recently change or install something in your car like a stereo or GPS?
The backup lights are a different bulb, then the turn signals and brake lights and The Number 1 reason would be that the bulbs are burned out and need replaced. Good Luck and Remember.Change Your Mind, Not Your Oil.Use the First In Synthetic Motor Oil's.See My Bio For Information & Contact Details.
Are you sure you need the fuse for the cruise control. My cruise control wasn't working, neither were my brake lights. All 7 bulbs were burnt out. When the brake lights were replaced the cruise control worked.
Make sure bulbs were replaced with EXACT replacements
The dash lights on a 93 Toyota 4Runner are replaced by removing the dash trim and panels. When the dash internals are exposed, the individual bulbs can then be replaced.
well it seems to be a common problem it might just be the switch on the transmission
use BMW bulbs and parts
Check the bulbs,if not the bulbs you most likely have a bad ground.
Bulbs. All the bulbs are fed from the same fuse.
If a car's lights are not working properly, the fuses should be replaced. The light bulbs should also be replaced if needed.
Check the switch at the brake pedal .
Working brake lights are important for safety reasons while driving. It is important to check all of the wiring, if the brake lights are not working and the fuses and bulbs have been checked.
The dims lights may not work on a Ford Focus if the switch is defective, the wiring is damaged, or the bulb has burnt out. If both bulbs are out, it is most likely within the wiring.
Change brake light bulbs Just remove the rear license plate. You can change the backup lights and brake light easily.
The light switch.
There is a backup switch in the gearbox. When you shift into reverse, the gear box switch contacts the switch and lights the white reverse lights. If you find that the reverse lights don't work it could be that the switch is not being triggered by the mechanism inside the gearbox. This is providing that everything else is working; wiring,bulbs,etc.
