Buick Rendezvous Flickering Instrument Panel	Sign In

A couple of months ago the A/C went out and the lights in the Instrument Panel started flickering. We didn't make a connection at first, but after resetting the Body Control Module (by disconnecting the battery...) everything started working properly. But it didn't last long. The next day, the A/C had quit again and the Dash Lights would flicker when you're between 15mph and 50mph. They turn on and off rapidly. Including the radio. The headlights would flicker if they were set on automatic, but if you turn them on manually... they are fine. At speeds under 15mph or over 50mph... everything works normally.

The flickering is very predictable, and has a steady rhythm. It is not erratic.

One more thing... the dash says "AWD Disabled".

I have heard that it could have something to do with a wheel bearing sensor.

Has anyone else had experience with this? Is there a way that I can determine which bearing it may be... myself?

And is it very difficult to change one?

I've read many complaints about the "Flashing Dash" issue but I haven't found anyone that has solved it yet.

Anyone had experience with this?

Thanks

Just a thought: Perhaps there's a common ground that's the culprit. Guess I'd try adding grounds by jumper from and to items that are supposed to be gound and check for corroded or damaged grounding straps located here and there underhood and some in dash area.

If nothing else - isn't that special for the holidays

Thanks for the reply.

Check the grounds... that was one of the first things we did.

Flashing Dash Lights seem to be a fairly common problem with the Rendezvous.

I hope to hear from someone that has had, or is having the same problem.

Somebody out there already knows the solution to this problem.
