Hi Fishkey

Sounds like your alternator is on the way out, or has a bad earth connection.

You really need to have it tested, on an amp meter for its correct operation, and charging rate test.

There is also a posability it may be the headlamp relay, but normally I have found they just pack up altogether.

Get the alternator checked first.

Good Luck.

John.

Back lights are dim on speedometer, odometer


You probably checked this, but sometimes we forget.
The dial on the dashboard to the left of the instrument panel controls the brightness of the instrument panel lights. Turn the dial to adjust the brightness. Also, to reduce glare at night, the fuel and temperature gauges dim when you turn on the parking lights or headlights. You then adjust their brightness when you adjust the instrument panel brightness.
Turn the dial up as far as it will go to return the fuel and temperature gauges to their daytime brightness.
I hope helps and it's that simple for you.

Headlights go off when lights are switched from dim to bright ...


You need to buy a whole new clicker, same thing happened to me, eventually your bright lights will end up not clicking off or vice versa. and your turn signals will mess up. Get a new clicker, it's the easiest solution, but not the cheap one. mine was like 200$

If the noise sounds like a weeeeeee that increases in pitch as the RPMs increase, and you haven't heard this sound before the 'problem', suspect the alternator...

You have a bad ground, look out by the battery for a bunch of black wires screwed to the body of the car, check that they have a clean and tight connection, scrap off any paint under the wires.
