My center console will not come on. This includes the display for the radio and NAV. Is this controlled by a fuse or a relay?

fan control relay. go online for parts and location

Backup Lamps
The TURN SIG fuse in the console fuse block supplies battery positive voltage to park neutral position switch. When the gear selector lever is in the REVERSE position, power is supplied to both of the backup lamps. The backup lamps are grounded at G401 and G402.
Do you know what DTC'S - diagnostic trouble codes are ?
DTC B2552
The body control module (BCM) controls the backup lamp relay. The BCM grounds the backup lamp relay control circuit energizing the backup lamp relay. The BCM connects directly to the center console fuse block with no external wiring between them.
DTC B2553
The body control module (BCM) controls the backup lamp relay. The BCM grounds the backup lamps relay control circuit energizing the backup lamp relay. The BCM connects directly to the center console fuse block with no external wiring between them.
Backup Lamps Always On

1. Turn ON the ignition.
2. Shift the gear selector lever to the REVERSE position and then to the PARK position.

Do the backup lamps turn on in REVERSE and turn off in PARK?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3

3

Remove the backup lamps relay.
Do the backup lamps turn OFF?
Go to Step 5
Go to Step 4

4

Repair a short in the backup lamps relay switched battery positive voltage supply circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you complete the repair?
Check the back-up lamps relay #45 in the center console fuse/relay box .

Inside of console, behind the right console access panel

Check

XL7 not XL-7 (the dash matters big time)
i'll guess its a dash.7
REDUX
in your post you said fuses are good (tested too)
have you checked and reseated the connectors on the OBJECTS that fail>?? (that is free to do)

we now learn many things fail on car,
even HEAD LIGHTS?????
and no statement of what works. in total!
does car drive perfect night and day?????
just a clue here, and win big. huh>?

I can't drive your car and see all those many things failing,& that are. ok .. and what does not fail....

but this car has CAN-bus (or the like)
a NETWORK for sure, and bus structured.

and does not work like some 1990 Vitara.
at all, not even close to same. (forget them...)
it's a BUS system.
each switch you throw sends a command on the bus.
it's failing I bet because of communication errors
that you fail to see because you did not use a real scan tool at the time of failure.
it must be scanned while failing !

cant fix it if its not broke,...(unless you drive
scan and log data. like i do all the time for all intermittent of any kind....)



does it fail engine running?
is running battery voltage at 13.3 to 15vdc
if voltage is low all computers in car will go nuts. (same with your cell phone)
this is a fact and what i check first?
valid battery voltages first.
2nd after fuses, (done already)
then scan it. using a real scan tool
not some relic.
a real tool can see all CAN buss errors
U codes top the list.

P1,p2, p3 and B codes too.... all seen.
failing.

you can buy tools
rent tools
or get the car scanned failing at any ASE shop.
car parts store may have junky or relic tools.
(i can name 10 that are)
some tools only do old federal P0xxx codes. say some old 1996 tool.

try a real shop and win. really

The fuse box with spare fuses, fuse removal tool and relays are located on the left wheel arch inside the engine compartment.

23 - 5 Amp Unloader Relay (K9), Rear Defogger Relay, Combination Switch, Climate Control System, Clock, Instrument Cluster, On-Board Computer

31 - 5 Amp Climate Control System, On-Board Computer, Instrument Cluster, Clock, Chime Module, On-Board Display

45 - 7.5 Amp Wiper Relay, Wiper Motor Relay, Clock, On-Board Computer, On-Board Display Check Control Module

iIn the glove box

on-board computer 23 45 (10-93 to 09-95)

on-board computer 23 45 (10-95 to 09-96)

on-board computer module, center console

It is located on the fuse panel on the Passenger side.
Look for the removable panel that is located below the radio/center bezel on the right side (passenger side). It's not part of the center shifter console, but just forward of it. Remove the panel marked "Fuses"! You will find the Wiper Fuse in this panel along with the fuses for the Radio, Accessory Power Plug/Lighter, Power Door Lock & Window Relays, Fuel Pump Relay, Cruise Control fuse, exc......
Hope this info helps!

Its in the center console below the radio on the passenger's side. There are two relays there, the main relay at the top, and the fuel pump relay at the bottom.
The fuel pump is controlled by the MFI control relay(the ecm/fuel pump).

sounds like you have a loose connection somewhere underneath the console.

Hello! In the Central Junction Box is fuse # 26 (10A) which powers the Battery Saver Relay...This relay, in-turn, controls the Power Windows, Electronic Shift Module, Glove compartment Light and Cargo light...If the fuse is good, suspect the relay...The Interior Lamp Relay and the Battery Saver Relay are the same...Either one could be at fault if the fuse proves to be good...See photo of relay below...Relay module Above right of gas pedal or lower left of AC/Heater/radio. It is an ugly place (Behind the center console)...

This is a documented fault if fuse #26 keeps blowing...The wiring on the rear of the relay module has a history of shorted and burnt connections on the socket of the Battery Saver Relay...Keep me posted...................Guru............Saailer

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

I know this is an old thread, but my 2006 325i Nav screen went bank also, but the radio still played. I noticed the glove box light and trunk light did not turn on also. I was told from mechanics is was probably a CID module for $2200, even though I mentioned the glove box and trunk light light were out and specifically inquired about a fuse. The mechanics never checked the fuses, because I checked my fuses in the glove box and found the fuse 61 marked with a BMW symbol that looks like light bulb was blown. The Nav screen started back up once the fuse was changed.

there are alot of fuses that control radio/ nav system with a few computers, if you use a scan tool to scan computer it will give you codes of what is wrong, anyway here are the fuses i found, left side of engine compartment # 26 is one fuse then left side of dash theres another fuse/relay box and at #16 and #1 are two more fuses then there are more fuses for modules and computers than run that system, good luck hope this helps.
