2000 C280 Sport Battery keeps dying
 

Hey guys,

I have a 2000 C280 Sport and the battery keeps dying if I turn off the car. I have had the battery replaced three times with brand new batterys but I the mechanic I talked to said there is a short in the instrument cluster or something I dont know. There is a short in the odometer or something and he wants $1600 dollars to fix it. Also my instrument cluster is messed up as all the digits are disappearing. Should I get a new instrument cluster ? or just fix the short? also my A/C stopped working. Thank god winter is coming up hopefully the heat works.

thanks,

how does he know the cluster is shorted out? thats a 1000 dollar part.
