#439 of 477 Low mpg on short drives by lyainna Feb 07, 2009 (9:56 am)
Hi, I have a 2002 Buick Century. The last few months, I noticed my mpg going down. I used to get about 400 miles to the tank either short or long distance drives. Now, I still get about 400/tank on long distance drives, but my short has dropped drastically down to 180-200 miles a tank. What would be a cause of this?

I have a scangauge installed and can monitor gas mileage on the fly plus lots of other things going on under the hood. I see the exact some thing here.
#441 of 477 1999 century rear lights by glennsbus Feb 16, 2009 (7:49 am)
My reverse lights and license plate lights do not work. it isnt a fuse or the bulbs. I imagine it is a mercury (or similar type) switch on the trunk lid. Does anyone know it's location? Replies to this message: scottm7635 (Feb 16, 2009 9:30 am)

I found my issue in the wiring going from the trunk lid to the car (int he right hand side trunk jamb). Open up the plastic covering and check all the wires. It looked like the trunk hinge caught my wires and cut them off, and they were all crossing each other. Hope this helps you!
#443 of 477 I bought a battery replacing it doesn't seem straitforward by vektor67 Feb 22, 2009 (9:53 am)
It seems I need to remove a support beam or whatever it's called. The bolts are quite seized. Also after purusing the forums here I begin to doubt that the battery is the issue. The problems began after I allowed my battery to drain completely. It should have recharged completely however. Each morning it doesn't start. Eventually I get it started using my portable jumper but only after much finagling. I do wish to pop the new battery in however since I can't return it. Some simple pointers on doing so would be appreciated it's 14 degree's outside and I don't wish for it to take all day. thanks.

Replying to: vektor67 (Feb 22, 2009 9:53 am) I had a similar issue in the past and it was more the alternator that needed to be replaced for me. You might want to check that also.

Replying to: vektor67 (Feb 22, 2009 9:53 am) Hi, I had the same exact problem, It was the alternator, tested bad. They replaced it problem seemed to go away, the following week the new part failed and they replaced it again. seems to be fine now. Yes that brace needs to be removed to replace the battery. I soaked the bolts with wd-40 then it come off without a hitch. For the record my 2000 buick century has 58000 miles.

#447 of 477 Re: 1995 Buick Century Electrical Problem [bulledawg] by jrp45 Mar 09, 2009 (4:57 pm)
Replying to: bulledawg (Aug 16, 2005 3:27 am) an electrical short in your system, get a meter that measures current and voltage and test your battery and the connections. I had to replace the battery cables and the battery then I had the alternator tested at autozone the person testing it said that it was still good but something was going bad inside it the way it sound it sound like metal grinding so I replace the alternator, since I replace both battery and alternator my back windows will not roll down so I checked the fuses they where blown this is a buick century 2000
