ICC not working

[Nicholas53]

The wipers and flashers do work. The reverse lights don't work but they havent worked since I had the car. There is a problem with the TCM but the radio was working then. Will check the accessory relay. Fuses are all ok.

Double check reverse fuse with a test light

Could be the motherboard in the back of the ICC (The central dash unit with the radio, A/C buttons, screen, etc). The solder joints on the board start to seperate/dislodge/corrode /whatever the technical term is ... and things stop working.

I've replaced a few ICC's over the years (in different cars) when this has started happening... but late last year we decided to have a go at fixing one instead.

I took the ICC out, and pulled the motherboard out of the big rectangular metal box at the back of it (not the CD player... but the one with the big main plug on it)... then I gave it to my mate James who's good with electronic boards... and he touch soldered all the solder joints on the board... then I re-installed it and put the ICC bac together.

That was around Sept last year and everything is still working reliably

Before you try this yourself, just note that the car won't start once the ICC has been removed ( I've got other cars, so didn't matter for me). I've also got a couple of spare ICC's (kept some previous stuffed ones) so I had back up.

If you choose to fit another ICC, you'll probably need to get it security coded to the car (though, sometimes you can be lucky it just works). Car will start but the rest won't work until it's coded.

Good luck sorting your issue
