Question about 2001 Chevrolet Astro

1 Answer

Had to re-wire the tail lights after a small fire which fried the rear wires. Cut out all the melted wiring in the harness and re-spliced the wires. tail lights work, turn signals , but the brake lights do not appear to be working. there are two white and two grey wires which i could not match up because there is no color coding on any of the wires from the harness.

See your GM dealer they will print out a wiring diagram for you, Look at the brake switch under the dash, I,m pretty sure they have a couple of white wires and an orange. The wire harness runs along the roof on the L/F side, What we use to do is run temp wires to test and varify everything and then do it perminantly. Good luck Kirk fc6fc

Hello i have a toyota camry 1992 and my passenger side marker wont turn off ???

That's very odd, because the wiring for all of the side markers are just splices from the nearest park lamp wires- the rear tail light in the rear (and the license plate lamps are also splices from these tail lights), and in the front side markers, they are splices from the nearest park lamps. Do all the other park lights work and turn on with the park light switch on? I would examine the 2 wires from that side marker's socket to the wiring harness it goes into-the power wire would somewhere splice into the passenger tail light wire. The other wire would be a ground wire and also splices into a ground wire for the rear end. To be on, the marker lamp would have to be getting power from some live source. I can't imagine where. Does the rear passenger light work correctly?

In that harness to the rear where the park lamps run, there might be a live wire going to an electrical trunk latch switch, or maybe a trunk lamp. If the wires were frayed right beside the side marker wire, you could have some cross feeding of power between the two. Let me know, we always appreciate feedback.

2000 Nissan frontier no tail lights, keeps blowing 10amp fuse. Disconnected both tail lights. Same problem.

Yes. Your 1/2 way to having it fixed. Now you have the problem narrowed down to a small area. Now trace the harness from where you have it disconnected to the tail lights.Look for a wire that is pinched or rubbed thru. Look close at wires in the tail light housing area. It will be something fairly simple you shouldn't have that much of a problem seeing it. Your on the right track and doing good.

Hey,I have an 03 chevy s10,I recently tried putting a pig tail on it (straight wired) and had no luck,gave up and crimped all the wire back together,and today a guy at work noticed I had no taillights,but...

I would check your tail light fuse first then test the brown wire in the tail light harness where you origionally cut into it. With the lights on there should be around 12v on it. if not you may have pulled the wire too hard and broke it upstream. Test to see if there is 12v at the fuse ad if there is, your trouble should be in the wire between the fuse and the spot where you cut into it.

you have a very serious electrical short and need to first find out where the short is. Then rewire the circuit. Not a job for an amateur. Take it to a Certified Mechanic,

1999 sentra gxe dont have tail lights or dash lights. Was blowing 10 amp fuses until someone put in a 15 amp fuse. now even with new fuses got no rears or dashlights

That was my first thought, too. But it would not "fry" the whole circuit, so don't give up yet, using the higher fuse may have just cost you one more step of finding the problem.
So is it still blowing a 10 amp fuse? Either way what you really need is someone with a voltmeter or multi-meter to track down where the power has been lost. Most cars have the tail (or park lights) and the dash illumination lights on the same circuit, therefore using the same fuse, so an electrician could start by checking if the fuse has power with tail light switch on, then checking the wire going up to the dash, and how the tail lights wire is spliced with that or separately from the fuse and then routed to the rear.
It always helps to have a wiring diagram, sometimes absolutely necessary with involved circuits. Your problem should be simpler, not so much to look after, although the colors of the tail light wires may be needed. The person with the voltmeter can follow the wires that way, sometimes you have to pull a harness apart to find the wires you need. It may take a little time, but anyone who knows how to use a voltmeter should be able to find the problem. It does take time, sometimes, alas.

Tail light electrical connectors are fried, i need to replace the connectors cant find them online? help

Call your local junkyards to see if any of them have any Silhouettes in their inventory with tail lights still installed. If they do, remove the tail light that you need, disconnect the connector and examine the connector (both Male AND Female sides) to make sure it's not fried too. On mine, both the male and female pins connected to the green(Ground) wire in the vehicle harness that was corroded.

If it looks good, install the connector and cut the wiring on the vehicle side a foot back from the connector and remove the complete tail light assembly with the connector.

The Female connector is built into top of the Lamp Holder Assembly and since both pins are corroded, the Lamp Holder must be replaced at the same time as the harness side.

Cut the damaged part out of your car leaving enough of your harness to splice the wires together. I soldered mine and covered them each with shrink fit tubing at the joint then wrapped all the junctions with electrician's tape for protection and some water integrity??

By the way, the complete Tail Light Assembly cost me $40.00 and I wound up with a spare left lens!

Hope this helps.

How to wire box truck for tail and brake lights?

The wire harness for the back lights comes in 2 pieces. Undo the center bolt at the fuse panel on the engine side of the firewall and pull the left side wire harness off the fuse box. That is the one that goes to the back of the truck. There is one wire in it that you will have to cut because it doesn't go all the way back. The second connector is under the box near the rear bumper on the driver's side. It runs to the lights from the first harness. It is prone to corrosion and may be your problem. If it is just cut it out and splice the wires together, using connectors and heat shrink tube. Then tape over the tubing and you should be good. Chevy tail lights are also prone to chaffing inside the box at the tail light so if you are haveing trouble check for that. Just tape them up and repostion them so they don't chafe. Also check the ground wires at the back. They very often rot off or stop making a good connection from years of road crud. The light sockets are available at any auto parts store if you need them. Hope this helps.

2000 oldsmobile silhouette electircal problems

you need to remove both rear tail lights and disconnect the plugs, look in the plugs and you will see 6 contacts look at the middle contact on either the top or bottom, the one the is connect to the black wire will probably be melted, you may be able to go to a junk yard and find one that does not have melted contacts and cut the harness about 4 inches before the plug and use splice connectors by matching the wire colors.
