Question about GPS

2 Answers

Buick Century 2004 - Problem light on dash flashes on often, stays on & then goes off on its own. Mechanics first thought it had to do with anti-brake problem & would be costly. After puting it on diagnostic equipment reported not anti-brake problem & probably wouldn't hurt anything. However, being a handicapped 81 yr. living on SS, it does bother me not to know cause & live in fear that it might end up being dangerous and/or a costly problem. Your help would be appreciated. Thank you.

First off I highly recommend next time the light is on to take it to an autozone and they can scan and give you the exact problem code. Once you have that code you can report back here and that will give me a much better idea of what the problem could be. It could be something serious but it could also be nothing serious at all. once you have the trouble code it will tell us.
Thank you,

Look 1st we must know what u are calling a problem light? is this the yellow check engine light, if so then this light indicates that you have developed a fault in the electronic engine or emission systems controls, in order to know what to check for this problem need to know the exact fault code(s) the technician received, there are over 200 fault codes that can turn on the check engine light so guessing is nearly impossible

    In addition, the "service engine soon" light goes on as well as anti-lock system light (a diagnostic test

    showed no problem). Yesterday, I drove over 200 mi. & light never went on. This morning I made

    2 short trips & lights came on twice. Please help

    I don't think u understand it is not that simple these kinds of problems require testing, rejecting my reply doesn't change that, I have 35 years of experience with this work and I do know what is needed, you need the systems of the car tested, i need the system fault codes that are stored in the computers memory.

My inlaws' 2004 buick rendezvouz: the dash lights don't come on. Dealer says no dash lights were installed on that model. Chris

The dealer is blowing smoke up your tailpipe. I couldn't find a manual for the '04, but the '03 and '05 have identical controls for the dash lights, so it's a very good bet the the '04 is the same. Here's a link to the manual for the '05 -- you will find the dash light control on page 3-16.

P.S. You might want to print the page and confront the dealer with it . . .

My dash light went out on my 1990 buick century.

Find your fuse box, read the cover and find the cigarette lighter and match the drawings with the arrangement of the fuses, when you find it, pull it out and check if blown out or open circuit, then replace it with a the same value of amp. ok

Buick century 2003, slow drain overnight, wont start in morning

To know for sure you need to do parasitic draw testing ! Not looking for a magical fix on here . has anyone ran into any issues that may cause drain, like glove box light switch etc,???? In my thrity years of repairing vehicles have seen a lot of thing's cause this problem .Back in the 80's when i first started at chevy dealer saw glove boxes stuff full ,to the point light would stay on . These day's more like a module not powering down when it's suppose to. Hooking up a amp meter between the neg. battery post and neg. cable an checking amp draw. If it's over 80 miliamps you have a draw on the electrical system. Pulling fuse's till the draw goes away . find what all that fues powers and isolate the different circuits till the draw goes away . That's kind of the long way now a days . There is a much easier way ,voltage drop testing accross the fuse's .

I replaced all turn sigal bulbs & right front will not flash?

If the light stays on instead of flashing than its a flasher which is located under the dash either driver or passenger. Copy and paste the link below to view a picture of the flasher.
