STARTING PROLBEM
 

HOPE SOMEONE CAN HELP, MY CL55, GIVING STRANGE PROBLEM. YESTERDAY WOULDN'T START, FINALLY SHE DID. I THOUGHT IT MIGHT BE BATTERY. PUT THE BATTERY CHARGER ON HER, THIS MORNING CHECK IT. GREEN LIGHT FULLY CHARGED. USE IT ALL DAY, NO PROBLEM. THEN AGAIN IT WOULDN'T START, SLUGGISH FINALLY SHE TURNED OVER. NOW DASH BOARD IS OUT, WHEN I GOT HOME TRUNK WOULDN'T OPEN. TURNED HER OFF, TRIED AGAIN SHE STARTED NO PROBLEM, TRUNK OPEN NO PROBLEM. CALLED AAA BATTERY TEAM, THEY CHECKED BATTER, ALTERNATOR, ALL GOOD. JUST THE STARER WAS A LITTLE LOW, BUT NOT BELOW STANDARD. NOW SHE STARTS NO PROBLEM EVERYTHING GOOD EXCEPT DASHBOARD IS OUT. PLEASE HELP.

I worked as a tune-up tech and always pounded the service writers to define "wont start"
