How do you set the clock in a 1991 cadillac

Question edited for clarity.
Question moved to model category.

It is hiding inside the fuel tank, and the fuel tank has to be removed to get to it. What makes you think it needs changing? Did you test the pressure?

Start car. Press config button on radio. Then press clock icon should be in top right corner. This should bring up clock set menu. Adjust clock to the correct time.

In order to set the clock, you must go to the menu-main on your display where the radio is, go to setup, scroll to clock, and follow the prompts to set time. Once you've set it, click ok or done, and your display will adjust to the time you've set.

probably a bad starter.

Your owners manual should have instructions on how to do that.
By the way - why are two different model years displayed for the question?

Library is the best place ever, take a pocket full of change and you can make copies of the pages you need from Chilton's Ref Books

in dash radio has settings options....scroll to set time and set it as normal. when you confirm time and exit out the dash clock will adjust to time you set

The lines should be differant sizes.. Did you check it? Ther should be a diagram on the cover over your radiator showing you the set up.. Hope this helps..

Here ya go

This is a common problem with all cars and trucks with airbags, it is caused by the rotating contact under the steering wheel we call the clock-spring, why this name? because that is what it looks like, the coil turns with the wheel to provide a solid contact with the airbag and other steering wheel related functions such as the radio or horn and cruise in many cases.
