The reason the fuse blows/melts is because there is excessive draw. The other alternator could be wired wrong. Check to make sure the wires are correct gauge.

SOURCE: Right hand side tail light short circuit Fuse

you must have another bad lamp either in the front turn/parking light circuit or the left side rear tail, cause most tail light fuses feed all 4 sides

96 S10 BLAZER 4DOOR FUSE BLOWS OPEING BACK GLASS


Sounds like a short in that circuit; disconnect the horn and try again, if that does not blow the fuse, the horn needs attention, if it still blows the fuse, the motor for the rear glass is the problem.

'89 S-10 Blazer/Tahoe package. Digital insrtument works sometimes and sometimes it flickers in and out. I sent it off to be referbished but still having the same problem. Here is were it really gets weird,...


I would recommend looking closely at your illumination circuit. There is a gray wire that if shorted could prevent the digital guages from displaying. I would look at the radio connections, especially if you have an aftermarket radio. Also, look around the lighter and maybe a bad dimmer switch.
To trace the problem with the horn fuse, look for shorts in the orange wire. Common places are around the radio or the screws that secure the panels under the dash (floor lights on the dome circuit).
As far as the no start, sound like old and dirty terminals and/or cables.

I have a 99 ram 4x4 slt laramie dome lights cargo light and map lights dont work, replaced #12 fuse 10amp under the black fuse keeper thingy on the drivers side but it keeps blowing it some times it lasts...


Classic symptoms of a frayed wire carrying current somewhere in the circuit, but touching metal, bare metal against bare hot wire: instant SHORT! Maybe a little spark there. Fortunately for you, you have a 10 amp fuse in that circuit which blows, and keeps the wiring from melting, and maybe starting a fire somewhere in your vehicle. If the fuse doesn't blow right away, the bare wire has moved away from contact with metal, but eventually, with enough movement it gets back into position and shorts again.
Enlightening, but not very helpful, eh? I'm afraid that's the way it is, Richard. Shorts like that can be very difficult to trace and find, without time and patience, a decent understanding of auto electrical systems, a wiring diagram for your Laramie, and knowing just what circuits that fuse protects.
If you have the owner's manual, it should list the circuits for that #12 fuse. I'd start with the dome lights, and remember, the door switches are part of that circuit. Good luck.

Igot a 1987 chevy blazer that my tail lights dont work and ever time i change the fuse it blows the fuse.The blinkers ,brake light and hazards work but no tail lights or park lights.


There is a short to ground in your tail/park light circuit. If your blazer is equipped with a trailer hitch, the first place I would look for the problem is in the trailer wiring. Otherwise, the circuits need to be traced from the fuse to the tail lights and/or all of the park lamps to find out where the short circuit is located. Whatever you do, DO NOT put a larger fuse in the fuse block. This will result in your vehicle burning to the ground. (I have seen this several times and it isn't pretty)

If you have a full-size Blazer, it should be a 20 Amp fuse. This fuse also powers your cigarette lighter, so check there also for a problem.

If you have an S-10 Blazer, it should be a 20 Amp fuse. This fuse also powers the courtesy/dome lamps.

As for the horn, inspect the fuse and relay and most common it would be a bad ground wire or worst a bad horn due to corrosion. Horn will be located in the drivers side fender.

Horn blows fuses


Don't bypass the fuse, you'v either got a short in the horn or the wrong fuse
it takes a 20 amp and I highly ecommend using a plug in breakr instead of a fuse

Put in a breaker, if it trips unplug the horn and try again, if the breaker trips again, there's a pinched wire, if it does NOT trip replace the horn itself

My 1990 Olds Cutlass Calais is missing the fuse box cover and therefore has no diagram for fuse placement. Is one available online? Copy I can print or just refer to in order to replace correct fuses?


I have always had a place in my heart for the Olds Cutlass. I own a '90 Olds Cutlass Calais--WITH the fuse box COVER. I went out to the car and removed the cover and have it next to me so that I can type the EXACT fuse order as they appear on the inside cover.There are 2 col. When I've finished the l/h side, I'll make a line to indicate the start of the r/h side. I will also put the Circuit on the left & fuse on the right. If you are ready, HERE WE GO:
