Instrument cluster acting weird/ other GMC Yukon electrical issues

[Matthew Snodgrass]

Hey guys,

I have an 03 GMC yukon XL with what I suspect to be a faulty instrument
cluster. Actually there might be a number of problems...

First of all the instrument cluster display cycles through the three languages
(English, French, Spanish) and also the personal trip odometer. The personal
trip odometer also resets occasionally. While all this is happening I cannot
control these with the steering wheel controls or cluster control.

I also have a parasitic draw coming from the high beam light, and parking
brake indicators (no the parking brake is not on). They're very dim and
sometimes flicker on and off. Sometimes the odometer also flashes up
intermittently when the car is parked and completely shut down with no key in
the ignition.

And finally I also have a right rear door ajar message the comes up when the
door is closed. Again this happens intermittently. When it is happening the car
is hard to lock.

Reading things online I first thought it was the BCM that was going so I
unplugged the BCM connector and all these things still happen EXCEPT for
the cycling through of the languages and personal trip odometer.

I've used an ohms meter to see if there is a resistance coming from the door.
I'm getting 0 both when the door is open and closed. Does this mean the door
is a seperate problem to the rest? As in I need a need door actuator?

I'm banging my head against a wall lol.

Does this mean the parasitic draw is an instrument cluster issue, the door ajar
message is a door actuator issue and the cycling of the languages and trip
odometer is a BCM issue?

Any help would be greatly appreciated.

I’d start with a new cluster, they’re infamous in those years
