the reading of the mileage has gone out.

thanks, a lot of the components are affected...think how the headlights can go yellow and weak...this is because of a corroded ground connection...kudos to you my friend for not sayin' "it works, why fix it" as if things will get better by themselves...as a matter of fact metals always react to their ambient environment.....steel will rust when exposed to air for example...all this is overlooked when it works alright~
