Question
This is for a 1994 STS. My instrument display has started to cut off and on randomly. When it cuts off I loose all the analog gauges and the digital displays and the defroster cuts on to high. then later on it all comes back on for a short while working fine, but everything except for total mileage and oil life have been reset. Any suggestions?
Thanks.

Answer
If you are mechanicaly inclined or know of someone who is, You will need a DIGITAL VOLT/OHM METER, Simple electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture. I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information necessary to fix your vehicle.
