Clicking noise in Fuse box when wipers work in car

alirob12

Hi, there seems to be a little problem I discovered in my ford focus 05,

When I use the wipers – I can hear what seems to be a click in my fuse box (under the glove compartment)

It only clicks when the wipers start and stop (not when they r continuously working – only when I do the single wipe or the very slow one) the click is also hear when I activate the rear wiper. Any idea what it may be??

Many thanks

Leave the wipers on all the time, that will cure it

Thx, any idea what it is and why it started, and how long should I leave them on, and it won't do any damage will it?thank u

Electrical relays are mechanical switches and the 'click' is the relay making contact. Call it a design feature if you like.

You can leave them on as long as you like, it'll not do any damage. Don't worry about it.

No I donth think it is the relay 'tick' that normally Is heard. I ve never heard it before and have had the car 4 over 1yr. Its not heard when they working fast, only on slow front and back? Interesting...

It does sound like a relay. The relays on most of my cars were always in or next to the fuse box.

I suspect that when the wipers are on constantly the motor turns continuously, but in "intermittent mode", a timing circuit is used to turn a relay on/off, which starts/stops the motor.

^^^this is def the correct answer

assuming that the question was serious that is.

i bet you cannot even change a bulb can you?

Of course it is a serious question plus I can certainly change a bulb and a few other things thank u;) well I do 30k miles a year and its the first time I have heard this noise, and believe me - it does rain a bit in the uk so the wipers r used daily and I kno how the relay works and it is like he relay noise, but it is just louder than usual, it wasn't like this yest, that's why I decided 2ask ppl who know ab it..
