The display on the heater and AC control panel may become dim or go completely blank. Our technicians tell us the control panel must be replaced to correct this fault.

    Illumination of the odometer, heater display and driver info unit are all controlled by a series of 0.5 ohm resistors on the printed circuit board of the affected unit. With some effort and skill you can take the dash apart pretty easily and replace them with resistors available at Radio Shack. I had this happen and for $3 worth of resistors and a couple of hours time I had everything working 100% again. You can find short video's on You Tube on how to do this repair.

    I have a problem with my HVAC control being very dim and hard to read, especially in the day light and even at night.

    HVAC Temp. display not working. Odometer & gear shift position display not working. Just purchased the car a couple of days ago and the Odometer/Gear Shift display was working when I test drove the car, but was VERY dim, but now has cone completely out. The HVAC temp. display was not working when I bought it. Have not tried any repair yet. Just now searching the net for suggestions. Bob

    HVAC display dim or not visible. Display will come back briefly (few seconds then fades) if front face is tapped.

    I never had it fixed. It is still dim to this day so I operate blindly by counting the clicks. Unit still works fine. Also, it will randomly light up fully but very rarely. I don;t know what triggers this.
