Dash Light Anomalies

[sfsvx]

1. When the dash lights are on, and I push the button on the end of the turn signal stalk, the lights that are supposed to get brighter do. What seems strange is that the climate control buttons go dim - not the labels such as OFF, AUTO, etc, but the buttons themselves.

2. When I adjust the brightness of the dash lights using the ring on the turn signal stalk, the low position is very dim (barely visible), the second position is noticeably brighter, the third position is brighter still, but the fourth position has no effect at all.

3. The temperature display on the climate control is intermittent - sometimes on, sometimes not - but the climate control itself works like a champ.

Are these: a) normal; b) abnormal, but nothing to really get worried about; or c) signs that something really expensive is about to happen?

I'd appreciate any feedback.
