I can't get ahead with this truck. Every time I fix something two more things break. The new one is I came out like normal started up the truck and no display on my overhead. I always look at in the morning for temps of the roads before my drive. Any tips? I think I checked the correct fuses but it was early and cold as hell. How cold I don't know cause my display was out. Is replacing it my best bet and where would you guys start to look for one. I have the old one out and will check to see if anything stands out on the circuit board or if I have proper voltage at the terminals. Thanks.
