My Volvo 850has a new expensive battery Temps have been very cold, single digits. I have not been driving it but starting it on the regular. Has been fine until it wouldn't start. I jumped it and got it going but now the digital clock display and info. is gone. Blank no digital readings at all! Warning lights work and speedometer. I checked the fuse, no corrosion and seems good. Is there a light in the cluster that is needed for the digital read out?? Thank you in advance. Patti Jo
When you say « starting it on the regular » do you mean start it and run for 2 minutes then off or start it and do a 20 mile drive to get it warm?
To keep the battery charged if it is not getting long runs then you should consider a battery tender - this will keep the battery topped up without overcharging it.
If the car has got very cold, and it sounds possible, those displays are affected by temperature, so if you get the while car warm then the displays may well function again - I would not take them apart until you have got the car warm...
