1998 GMC Safari Van Odometer Light Flashes and Transmission Shifts Funny
While driving on the freeway, the illumination for the odometer and gear shift position on my 1998 Safari began dimming then brightening again. Soon the transmission began downshifting to 3rd then back to drive. After a mile or so everything went back to normal and I drove the last 85 miles home. In the morning the car started fine, but the area of the odometer was dim and then went blank. While driving the transmission never never seemed to shift to drive and might have simply stayed in one gear (3rd I think)the whole time. After stopping the car and turning it off I could get the lighted odometer area to again be luminated as I turned the key on, but as soon as I started the car it went blank again.
