SOURCE: head light bulb replacement

Open the hood. Look at the top edge of the headlight. About 1/3 to 1/4 of the way in from the inner edge of the housing, you'll see a rectangular clip, and about 10" outboard of that clip, you'll see a matching one. Simply pull up on those clips - they're slide locks for the headlight housing. Once you pull them up, you'll be able to pull the whole headlight housing out towards you, and from there, you can unclip and remove the bulb sockets in question.

SOURCE: Tail/brake light bulb replacement 2004 Olds Alero

In the trunk, in the rear corners, you'll see some plastic "caps" with tabs on them, similar to wing nuts. Remove those, and the taillight comes right off the back of the car. That will allow you to replace the bulbs.

SOURCE: running lights stop working 2002 dodge ram

This happened on my '05 2500 Dodge diesel last winter.After spending a full day checking wiring,fuses,relays and the headlight switch I determined the problem was with the (FCU) the front control unit which is mounted with 4 screws to the outward side of the fuse box.When i asked the dealer if they had one in stock they said they usually kept 6 on the shelf,so I figured if they stock this many then they must be a common problem.This unit cost a bit over $300.00. When i installed it I still had no front or rear park/running lights so I started to remount the fuse box and look for another problem and BINGO I felt the relay click and the lights came on,now I'm thinking did this unit need a few seconds to reset or was this just a flukie fix.Well the lights worked fine for 3 months and the same problem happened again.This time I installed my old FCU just to see if the new one went bad but still no lights,but as I was moving the fuse box around again I felt/heard the relay click and the lights came on.

So I took the fuse box out of the truck and completly dismantled it (dealer says a new one costs $700.00).These boxes snap together and then there are 3 points where the plastic is melted (studs) and these need to be drilled out to separate the top and bottom halves,then the box is easy to take apart.There is a printed circuit board inside that the FCU plugs into with about 40 small connectors and there is where the problem was.One of the lead circuits on the board had corroded and lost connection.I just soldered in a piece of jumper wire and that cured my problem although this probably could be repaired properly by someone with circuit board experience I was happy with my mickey mouse repair for now.

This may sound complicated but the fuse box can be removed from the truck in 10 minutes(honestly) it took me longer to make a sketch of the harness plug in locations than it did to remove the fuse box.Once you have the box out it takes about 20 minutes to drill the (3) plastic studs and split the top and bottom sections (there are no springs on ball bearings or other surprises to fly out as you separate the 2 parts) then if you don't feel you have the skills to check the board and do the repairs you can have an electronics shop do an inspection.

A couple of things that puzzled me while trying to find this problem was that the dash lights still worked,the chime that rings to tell you you have left your lights on still chimed even with only the park lights on,and there was no power at both park light fuses.

When i found out the price of these fuse boxes I automatically thought I'd get one cheap at the local junk yard..big surprise,they said they can't find enough of them to keep up with the demand and also said they often get calls from people saying that their fuse box burned up,so appearently there is a problem with dodge truck fuse boxes!! When I questioned the service manager at my dodge dealer about these things going bad he agreed and said they have replaced many of them.

Hope this helps and I didn't scare you too bad.

SOURCE: 03 Suzuki Alto - Dashboard, tail lights not working

I have this car it has huge electrical problems. Something in the computer/alternator/etc. I have no speedometer, all my internal lights are screwed up. I've had 2 alternators, a starter and 4 batteries in 2 years. Get rid of it.

SOURCE: Have a 96 Olds Cutlass Supreme, brake lights will

Try having someone push on brake pedal at the same time thay move the turn signal lever up and down slightly to see if your brake lights work this would tell me that you have a faulty turn signal switch because GM runs the brake lights thru the turn signal switch so they work if you are driving with your 4way flashers on.

2003 Olds Alero keeps blowing fuse For dash and tail lights

Likely there's a wire loose that's shorting to the chassis. The way I troubleshoot these is to put a lightbulb in the fuse socket, and then go under the dash, and move stuff around while somebody watches the light. When it goes on, you're close to the problem. Yeah, it's a royal pain, but that's the best way I know.

2003 alero. Low beam headlight out. I purchased a new bulb 9006 it does not work. There is power at the socket. Could I have purchased the wrong bulb? Should it have been a 9005? all fuses good highbeam...

The wrong one or the one you bought is bad. With so many different bulbs now, it isn't hard to get the wrong one, especially if the parts guy got it for you. The only way to make sure it is right is to pull the other bulb and check the number.

Fuel problem with 03 alero.......Sputtered, died, now wont stop

I am having the same exact issue right now with my 01 Alero. Been having electrical issues with lights coming on and off. ABS was kicking on a few times even. It started sputtering like it was running out of gas, thought that might have been the case. But after I put gas in it it still didn't start. Now it turns over but nothing. What ended up being wrong with yours?

2003 olds alero center brake light works but sides don't.

Replace bulbs, one of them is probally bad. Worked on a lot of cars, but my daughter 2001 alero showed me. The car had the same problem, bulbs looked good but one wasn't and that's all it took. Try brand new known to be good bulbs. Ed

Beeping Noise/Blinker Noise

sounds like your electronic flasher unit maybe stuck causing the noise. they are generally located under the dash on driver side just below the instrument cluster.
