Issues with partially lit dash and self resetting trip Sign In

The trip B keeps resetting without me pressing any buttons and the tachometer is only fully lit through about 5k rpms so I think I have an electrical issue. I don't have any problems starting the car and the alternator appears to be putting out about 14.1 volts while the engine is started so I'm not entirely sure of what to look for. The main issue is that my dash is only partially lit, the knobs for the rear window defroster and temperature knob is also dimmer than other accessory lights....

I originally assumed someone somehow got into my car to reset the trip, which would be weird but I only saw it changing, however with other existing issues with the dash cluster I'm not entirely sure that's the case. The vehicle also has a new set of keys which work with everything except the boot, so it may have been a preexisting issue from before I bought it.... What else could cause this, the only thing I can think of is a rectifier not charging the battery so long as the the battery gets charged enough it should provide enough current to all circuits....?

I'm driving a 2006 Hyundai Elantra

Ugg? Yes that battery totally matters it starts the car so not the up front issue IMO right now.
Basics and this will be a tough find: Dim or no lighting and resets of things you didn't assertively do? A reason is the dash cluster is empowered and grounded with two circuits one of which can cut out totally or partially not enough to recall the trip odometer.


Lost: What would be needed is the full diagrams of how all that is empowered and grounded some is full time battery enabled some is not no telling why these items are split up in one unit that probably is unfixable if inside it?
Not much help to you - sorry. Just maybe try the wiggle test on highly suspect plugs/wires that are to this unit see if it snaps out of it or changes it in any way while also watching it.


You could try a dealer for help my bet is you'll get some hourly rate to chase this but could be worth asking how they would approach it. Why - they have info if this is common available and what the fix is not easily available. Good luck,


T

There is only one lighting feed going into the dash cluster so if you have issues with only part of the cluster lighting up, all you can blame is the cluster.

I'm asking HT. Also have dug into some of this stuff just find a break in pos or neg and if or where it cuts out destroys many of these units just to take apart, sealed routing of "stuff" inside the unit - this cast "dash cluster."


Worse is how to you prove it's that close 100% so if all new is the fix it really works. What a no-win scene IMO hate problems like that one!
