Ok here is the latest problem I have been trying to figure out. All of my interior light do not work, as soon as you put a new fuse in, it blows before you can get it all the way in. I have try unplugging dome lights and vanity lights but still blows fuse. With this happing i believe it must have a short to ground somewhere. Does anyone have any familiar situations with this type of electrical problem. Any suggestions are welcome.
All other lighting works great.
As always the help here is great and I appreciate the help
Thanks

I have had this problem on other vehicles.

What sux is you will have to trace wires :mad2: to find the culprit.
 
I'm guessing it's the 95 in your signature? I wuld start by doing a visual inspection of all the door switches, and then checking the wires at your dome lights. You will most likely end up finding a wire that has chafed over the years laying next to part of the body. Unfortunately there is no easy way to trace down a short except to start with the process of elimination.
 
i would suggest pulling out the bulbs themselves. sometimes the glass gets seperated from the base, get twisted, creating a short. replacement bulb will fix it. happened a lot on exterior lights also.
 
Check the fixtures themselves, I would suspect the ones in the door panels as they are most likely subjected to water and corrosion if anything looks black that's a good place to start.
 
Had a problem (wasn't a short) with the dome light wire on my 94, was a connector that looked really f'd up but was a factory connection.... was located along the kick plate at the back of the drivers door where it runs under the carpet...
 
Glove box light should be checked out as well.
Then put a test lamp in the fuse holder and remove all the bulbs. When it dims you found the short and have bulbs left in. Faster than popping 100 fuses...
My 1993 has a bad wire under the plastic trim cover by the driver door. You know the one that is held down by 3 screws between the carpet and rubber door seal on the door opening?

You should be able to unplug each door by pulling the rubber boot out of the body and looking in the body side for the connector. Look under the dash before pulling the boot as the boot is a pain so if you can avoid it. This will eliminate the doors as the problem or point to them...
 
Put a fity amp fuse in there then look for smoke or a small fire. When you see the smoke or small fire that would be a good place to start looking for a bare wire.

Lol!

Reminds me of troubleshooting a snag on a cc130 with an old friend of mine.

We kept popping a breaker and the aviation electrician insisted it was being cause by a bad micro switch in an actuator. Since it was an actuator , we had to change it (electricians don't like to get dirty, we were "greasy paws")

Well, we knew it wasnt the actuator and the electrician was being a lazy sob ( didn't want to leave his coffee).

After a half hour of discussing it ( yeah, would have been faster if the electrician had just done his job) my buddy reaches up to the cb panel and pushes the cb in. Instead of letting it pop, he holds the f'er in!

After a few seconds of howling protest from the electrician, we see a waft of smoke from an electronics cabinet.

My buddy looks at him and says "unless the actuator is in the f'n electronics cabinet, you got some work to do you lazy f'n spark chaser!"

He always was more of a blunt instrument than a scapel.

I miss working with that guy.......

I can see why, no nonsense kind of guy:hihi:
 
Thanks for all the input, looks like im going fishing. To bad its not for real fish in the water but for a bad wire. I think I will look for it at all the easy places to get to, then put a circuit breaker in and let the smoke out of the wire. lol I know its not a good thing to do by letting smoke out of the wire but sometimes we need to, I just dont understand how they put that smoke in those wires. Lol ha ha.. Will let all you know what I find. Thanks David
