I have posted this before and I realy realy need help. I have a 1998 E320, when I start my car or its less than 75 decrease my digital read (climate - distance - time - error codes) is fine, but if it gets past 85 decrease it slowly fades untill I cant see anything. This is a huge problem because I live in San Diego and now that the weather will start hitting above 90 and even 100 in mid-day I will be driving with out this feature. I have no clue to why this is happening. I feel like it can be dangerous for several reasons, if something happens I wont know because I cant read anything. Once the car cools down it is fine, which makes me very confused. If you have a professional opinion and or have went through this please reply thank you.
