Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
Jeep mechanics 2005 Rubicon dash issues please see video
Any ideas, watch the video and see how the guages are flipping out.. Also get an occasional "No Bus" message on the odometer. Its not til you post these things that you see how bad you need to clean your vehicle....lots of road dust in there.

This guy says grease the electrical plugs with silicone grease. He said it fixed his.

Without watching the video, but reading the description, I say a loose ground.

This is very common in TJs. Remove and dash cluster and clean the connection at the back of the cluster. You can twist the pins on the connector slightly to try and provide a better connection. Also use copious amounts of dielectric grease when re-assembling.
It is very easy to get the cluster out, just a few screws to pull the cover and two that hold the cluster.
Google "TJ No bus" and you will find a lot of discussion about the problem.

You do not want to use conductive grease in this situation as that would just cause a short between the pins. Dielectric grease is used to prevent further corrosion and keep the connection clean.Originally Posted by foxtrot
Not a mechanic, nor any jeep experience.
"Bus" in the hardware context often would refer to a serial bus - plain speak, data connection. Intermittent problems would indicate likely connection issues. Pull plugs you can find (maybe download a clymers), blow out with air, use rubbing alcohol to clean, reassemble. You can use undercoated paper to polish copper contacts, or use conductive grease (which is actually kind of hard to find). Problems could also be IC (Chip) related, but it doesn't sound like that.
Knowing how vehicles are, you'll probably have to disassemble the forward half of the jeep down to the frame and firewall to access the one plug causing the problem.
Again, not from any vehicle experience, just electronics.
ETA: Don't just e.g. use any kind of grease, you have to verify it is 100% conductive. For instance, GE Silicone II (not a grease) is also used to completely insulate electronics. Most greases are better insulators than conductors and can make things far worse - not saying not to, just be 100% sure it is conductive.
Test by filling each side of an outlet and touch your finger spanning both grease pads. KIDDING on the last bit.

Not sure I would use any thing but "silicone grease". We called it "goose grease" in the avionics unit I was in. I worked electronic countermeasures pod ALQ-119's. It doesn't look too hard to fix the plugs faulty connection. I would just lightly scrape the sides of the connector pins with a pocket knife. That will remove the corrosion. Just be very gentle when doing it. And yes I do wrench on a TJ fairly often. Mine has developed a "death wobble". I'm hoping a replacement of all the front control arms will fix it...

Discussion is an exchange of intelligence. Argument is an exchange of
ignorance. Ever found a liberal that you can have a discussion with?
