Replacing the engine bay fusebox on a C3 1.4 2009

Post by mrdobing »

Hi all,

I've found the source of sudden (no abs/EPS/speedo) issues on my car is a completely corrded connection on the fuse box under the bonnet. The middle brown connector was blue and severeal pins snapped off... I believe this is the leaking washer jet issue..?

A second hand unit from ebay is about £35.

Is it a simple match the part no and swap?

Yes it is but how is your connector on the harness? Sometimes when they are like this the pins in the fusebox can break off & stay stuck inside the connector.
Does it smell like coolant? Its not uncommon on these for the coolant temp sensors to crack & coolant travels up the harness & into the fusebox or ECU.
Unplug the coolant temp sensor & check for signs of coolant in the connector.

Thanks wheeler. Yep, the plug was dirty too and one of the pins was stuck in so I'm trying to remove it before I get the new board.
Will check that when I locate it! Cheers

Might be worth asking the breaker for the connector too with as much wire as possible, the terminals can be stripped out of the plug.
