2008 Z20, my tach (tach/water pressure systems check combo) is acting up. I'm told there is a potentiometer on the back of the unit, but how the hell do you get to it? Do you have to remove the entire dash or is there an easier way I'm not seeing? Just looking at it I thought I could remove the screws around the guage assembly and remove it that way...No! Any help or suggestions appreciated. Pics would be a plus.
Thanx,
Don
