Corsa C water leak fixes. Drivers carpet wet + passenger carpet wet and Boot.

*update... I ended up doing this fix on another Corsa and wrote a more detailed guide. Between the two blog posts you can get a good idea what's involved and how to tackle these water leaks:

Comments on other threads encouraged me to finally write this work up. If your Corsa C has a water leak I probably have the fix listed in this long post.

These water leaks are a pain and happen gradually but if you catch them early then it's so much easier to dry the interior. Unfortunately my mates car was in a bad way and he lives on a hill which made the problem worse. Water ran into the back footwell, even growing a mushroom on the rear carpet mat. He was even de-icing the car on the inside and so I offered to sort it out even though it was winter and cold outside.

Drivers carpet was soaked so investigation started there, pulling the carpet right back and carefully cutting out the grey sound insulation sponge on the drivers side. The sponge was soaking wet and I cut it at the edges to ensure I could refit and glue it back into place. Research on the internet showed people who had tracked the problem to a perished rubber seal on a metal plate where the brake servo bolts too. I used a water hose on the windscreen and water started dripping from the plate on the inside and collecting in the footwell.....Bingo!

Corsa C instument cluster speedo cutting out and car wont start

Few years back my mrs owned a Corsa C and I did a little bit of work on it, so when a mate was having trouble with his Corsa I said "yeah I can sort that out for you". First fix on the list was the instrument cluster cutting out symptoms of this problem are:

- Car wont start with starter motor turning over but you will notice the dash is not powered on. If you physically push the instrument cluster back it will temporary fix the loose connection and you can start the car.

- Dash will cut out and the most inconvenient times like indicating round a corner. When this happens you loose the indicators until you push the cluster. This is quite dangerous at roundabouts so worth getting this fault fixed.
