Clicking From Under The Dash - R32

[iz32]

im getting a clicking sound from under the dash and my power windows dont work.

it began when i started the car whilst at the very same time put both windows up...

i assume there was a high current draw and something went click then windows stopped dead.

i have swapped the elec window relay in the engine bay around with the others and its not that.

The car starts and runs fine..... stereo, interior lighting, dash, lights, signals.....basically everything works all ok except for the clicking at regular intervals. when the click happens there is a current drain cos all the lights dim then its ok for a few seconds till it clicks again.

after checking all the fuses i found the mirrors/wipers fuse was blown but i havent used either of the items for so long i dont know if it was pre existing. that was replaced and the wipers work fine but the clicking is still there.

its not the black box in the door cos ive had/fixed that problem before

I've traced the clicking sound down to this....

what is it and what does it do? it only has 2 pins but clicks like a relay.

im yet to track one down and relace it....hopefully thats all that went wrong, but im curious to know what it is.

Probably the circuit breaker. Basically an automatically resettable fuse, it limits current in the power window circuit when the windows reach full travel so that the main fuse(s) don't blow. Sounds like yours might have called it a day. It's probably common to many Nissan cars with power windows and it should have the part number on it somewhere so shouldn't be hard track one down.

yea i found out today from nissan it is a circuit breaker but they didnt know what for...

cheers tho, now i do.

unfortunately i got one from a wrecker today (from a working car and at a fraction of the cost of a new one) and it still trips... gotta be a short somewhere in the power window circuit...time to fault find!
