(T) GP. Body Control Module faults...

I have a '58 plate GP 1.4 TJet I've owned it for a year, and it has been back 17 times.. the latest is because the Body Control Unit has flooded, i wanted to know if anyone has any idea where this unit is. all i know is that it is located in the dash somewhere. i have had a screen wash leak in the dash before (leaking through the glove box), and wondered if this could be a result??
Ill postmy whole list of faults when i have more time!!
Any help please asap!!

well to the best of my knowlage the body computer is in that area (behind the glove box along with the small fuse box)

Thank you, Thats confirmed it! the screen wash leak was fixed under warranty but not until fiat had put me off for a few days! Then a few weeks later dash lights started coming up, fiat said they couldn't look at it for a while because the dia machine was out for rep air, in this time the warranty ran out !! so ive now spend £1000 at another Fiat garage having work done to solve the lights but when asked about it Fiat say that my car does not 'meet criteria'! do you know what else has to go wrong before they realise how bad this car is!!?!

got called in tonight to collect my car YEEEEY!! ... paid almost £500 ...got given the keys.. and nothing.. same faults
