I'm not fimlar with the Magnum s . But perhaps try resetting the cpu , or disconnecting and resetting the battery and check your fuses that connect to your wire harness and then go from there. If it still happening and u can't do ur own , try to take it a local trusted shop .

 

Weird!! Agree, definately do a reset! Good Luck.

 

did the reset sorry no good
when to the dealer 89$ scan + extra time
Total 200$ later nothing same problem damm
he clean some ground on PCM and some connector, did not have any problem for 3 days but came back

so i wait until it completly fail

oh yea fan heater is going on and off also when the problem occur
(winter here)

I have the exact same problem with my Magnum R/T after 25 min of slow driving the lights first shut off then all the icons in the cluster comes on but when driving on highway never happened yet but for now car runs and did not stop what is this ? anybody have resolved this kind of problem?

 

We have the exact same problem, if you find it before me please share, so far it cost me 200$ with no result

thanks

 

did anyone ever find out the solution

 

Here at Alldatadiy.com, we do have symptom related information along with repair information. DTC are also in our database. Good Luck to you all with that issue.

 

had the same problem and the dealer had no clue, I changed the headlight switch and have not had any problem since.

 

The headlight switch is tied to all of the dash lights, the dealer will tell you it's the wiring hornes but it's not, plugged in a new switch and all the flashing went away.
