1. Lights on dim won't work. Bright work fine. Blue light bright indication on instrument pannel won't work. Fuses are fine. Of course have installed new bulbs. Relay or combi switch? Any ideas.
2. Horn works in afternoon but rarely in the afternoon. Mosture buildup or what?
3. Even after an oil change the oil is dirty by time auto is driven home. Even Chevys have clean oil after a change. How can I achieve clean oil? To drop pan was going to be $1,ooo. Ideas?
