Your battery is weak. Please, replace it.

If you allow this to continue, the needles will go all the way 'round and stick. o_O

Then you will need to do the instrument panel calibration.

SEARCH for details.
I will have the battery checked tomorrow , although the battery is only 16 months old , also the gauges are fine now , not sure what's going on

You didn't leave the OEM interior lights on while cleaning the inside did you? I've run down the van's voltage that way.

If the battery checks good (and you don't have corroded terminal/ground issues, check the grounds on the B pillar) then you would be OK I guess.

when I start my 05 limited , the gauges goes a bit crazy , they shoot way up and then come back down again .
Any ideas on how to fix this ? thanks !!
Sadly, this is the a known issue with the 2005 era vans. This is the model year for electrical gremlins. You'll be chasing this down over and over.

Yes, the AMP draw from the batter is weak. Could be the body harness or grounding issue or the connection under the battery tray.

Over these years here, people have just added 'additional' grounding from engine to frame, interior dash frame to body grounds, etc. It helps, but it's only a partial solution.

I feel for you. My 2005 SXT was a great van at that time. But the electrical annoyed me too. The 2006 is rock solid, no electrical issues either.

^^^ Those are sold as a performance upgrade to the Ricer crowd. :p 😇

More seriously, proper grounding DOES help the ECU interpret signals from the sensors.(y)
I did just that with my 2005. Yes, it nullified about 70% of the electrical gremlin issues for that model year.

One item of interest was, grounding the TB to the engine. That got rid of the gas pedal delay issues. And I didn't learn this from the minivan forums, I learned it from both the RAM truck and Jeep forums. It's a known issue with these FCA vehicles. An easy fix really.
