Hi, Does Anyone Know Where The Reverse Light Switch Is Located On A Ford S Max Please.

either on the top or the front of the gearbox.

I am guessing the reverse lights arent coming on. If so take the wire connector off the reverse switch, with the ignition on, join the two ends together with a piece of wire, if the lights come on then you know its the switch for definate, in not then its somewhere else.

Hi, reverse lights are flashing on there own accord. Some times with the clutch; brake or even whilst on stand still.

Sounds like a short, not necessarily the switch... Have you checked any other lights arent dimly lit?

[jayhus123]

All other lights seem to be ok although I have notice the head lights do flicker and I canbhear clicking on the fuse box whilst driving which is located under the passengers feet.

Clicking in the fuse box tends to indicate a poor battery. Get your batteries health checked out and you might need to replace it (silver calcium battery only!).

If the battery is fine, (I would be surprised) then you would be possibly looking at an issue with the fuseboard. Perhaps water ingress?

Would the battery power affect the reverse light madness???

Ok....I have checked the battery power on the on board system and its at 13.5 whilst the engine is running. Is that where it should be? With the reverse light...now it stays on when the key is turned once without the engine running.

OK, so 13.5 is good, that would be expected as its the smart charge, but then again I replaced my battery last month, perfect voltage reading, car started everytime but it kept throwing my car into chaos. Maybe put the battery on a backburner but dont forget about it.

So, if you put the car to electrics only, drop the car into reverse, the light comes on and stays on every time?

If you then start the engine and (handbrake tightly on!) keep chucking the car into and out of reverse, do you get a lot less consistency?

[jayhus123]

Reverse stays on regardless of putting into reverse. Start moving and it flickers randomly. Had to take the lights off yesterday as it got dangerous for other road users.

OK so that would suggest either a short circuit or a stuck switch. The concern for me, is that your car is clicking and going nuts at the fuse box.

Have you read the error codes at all?

[jayhus123]

There seem to be no error codes on the system. Over the weekend I will get the fuse box out and reinsert all the fuses. Its a bot of astruggle to get to as its under the glove compartment on the passenger side.

Might also be worth checking to make absolutely sure that the board isnt wet anywhere. I would also suggest that you get some compressed air, and blast each fuse holder to make sure there is nothing in there possibly shorting it out.

[jayhus123]

Ok it seems the clicking only occurs whilst going into biting and changing gears, something to do with clutch also when taking into reverse gear you can hear a click.
