Dash etc still die when brake pressed!

Hello all.

Hoping I can get this sorted as it's becoming a right pain in the arse now.

Dried out the damp drivers side carpet and possibly damp wiring aswell as hopefully fixing the cause with the hairdryer.

Still having the dash, climate control, reverse lights die when I press the brake pedal and recover immediately when you take your foot off the pedal!

Occasionally, usually when it's been run for a short while it sorts itself but regularly has it's fits in the morning or when it's been left for a while.

All electrical connectors in the drivers side kick panal were removed some time ago so no corrosion, re-loomed it all when it had aired and cured itself last week so now very puzzled.

Was going to start disconnecting things to try and identify it that way.

Don't have a wiring diagram yet but wondered if any of you knew if the fault it has is related to a particular unit or stretch of loom?

Please help before her in doors scraps it.

Cheers.

make sure your EKA code works-then disconnect battery
disconnect all bcem plugs,brass brush(swede brush) and electrical contact cleaner only.
Clean plugs and contacts,gently squeeze plug contacts and refit
check bcem earth and clean bcem fuse box feed and fuse contacts.
reassemble and connect battery.

I had almost the same problem but my dash and climate lights used to go dim just a little and it was the brake light swich started to melt, its very easy to check , its just at the top part of the brake peddle so its worth a look

Right, well I havn't soreted it yet, even with the advice from Fanatic, but I think were closer.
I think the problem is within the bloody BeCM again as more often than not the problem sorts itself when the interior of the Rangie has warmed up.
Saying that it is somtimes ok, but only somtimes when cold.
It is as if the rear o/s footwell heater is curing a dodgy solder etc.
I am loath to get the BeCM pulled out again and checked due to the cost, but I will have to sort it someday.
Any one else had this problem yet or can suggest trusty folk for me to contact for assistance?

Cheers for your pointers so far.

i had the same fault on a customers car a few years back, it was the main power feeds to the becm. the insulating block inbetween the terminal and the becm body had melted causing it to be loose on the inside of the becm so when power was pulled for any other system it momenterily lost its continuity, take the seat out and whip the top of the becm its a fairly straight forward job.

Thank you ABU just the guidance I needed.

Cheers.
