Where is the control to the digital image in the dash?
1997 pontiac grand prix Gt 3.8 windsheild digital speedeter
I have had my 1997 Pontiac grand Prix gt 3.8. For a year. There is a digital image that reflects off the windsheild so the driver can see there speed and radio stations at all times. I know where the adjuster to move it up and down and the light to make it dimmer is. But 2 days ago all the sudden the speedometer switched from mph to km?? Does anyone have any idea how to switch it back???.
