Hi all - I have a vauxhall combo van 1.3 - 2008
Last week I soldered a small led inside headlight switch and plugged switch back in and things went wrong - I found out I soldered plus to minus
I bought a new headlight switch since and fitted it
Anyway the display unit went , so I bought a second hand mfd unit and cd30 that are paired fitted them and display is back
I found one fuse has blown in fuse box so replaced that
The problems I have radio and display don't come on with ignition even though they are set to in radio
On display i have a F where temperature should be , fitted a brand new outside temperature sensor but made no difference , only way to get displayto show is by manually turning on radio, also the dimming switch dims the clocks and heater controls but not the display unit, also when radio is on and headlights are on the radio doesn't light up but plays radio stations and cds.
Checked all fuses in fuse box no more blown, checked voltage on battery 12.7, checked the plug at the back of mfd unit with multimeter and got 0.00
I keep reading about bcm but don't know where to look for broken wire or wires
Checked everything with opcom and no faults are shown anywhere
If anyone could help me solve this I would be so grateful as it's doing my head in
Many thanks in advance
