If you have a problem with the HUD dimming then this can fix your problem.
1. Remove HUD from car.
2. Remove 4 Torix screws from top of HUD
3. Remove ribbon cable and small 2-wire cable from circuit board.
4. Remove circuit board.
5. On the board there is a small photocell, the problem is that the cell has a cold solder joint. The cell is a 1/3-inch
Circle with a black square in the center. All you need to do is resolder the two legs.
6. Put everything back.
I was unable to find a replacement cell at radio shack. Monday I will look at a Digikey catalog and try to find the part.
The cell produces a small amount of voltage. The more light the more voltage. 0-.75 volts. Mt cell was working fine but the joint was loose. When the board heated up it lost the joint increased resistance to the point that the HUD lost the voltage reference.Hope this helps....~Larry~
