Default Another electrical problem...

Ok about 3 weeks ago now I had to replace my multifunction switch. I had it done at a corvette dealer here in dallas. All was well for the last 3 weeks and a few nights ago I flipped the lights on and I blew a fuse #6 to be exact. Dash went dark, fogs wont respond, lights wont go down. I swap the fuse lights go down all is well. I turn the lights back on to test them and boom fuse goes again. Which leads me to my new question.

I read on here that a loose/bad lead on the new switch may be the culprit? Maybe the wire harnesses in the accordions are finally biting me in the ***? What else should I check?

A lose wire will probably not cause the fuse to blow...unless...a wire has melted somewhere and its contacting another wire. Was or is there any melting taking place at the headlamp switch connector? I suggest that you start looking at the wiring going to the headlamp control module for chafed wires to the frame. This means at the steering column to anywhere near the headlamp control module itself.

Your going to have to remove that switch and look for damaged connectors. The plastic that the FEMALE pins fit into can and do melt due to a LOOSE FEMALE pin. The female pin deforms and no longer fits tight on the male pin and that junction gets HOT and melts the plastic connector and the pins can touch each other.

When my #6 fuse was blowing out constantly it was a shorted out drl bulb. I had put in some leds and one went bad. replaced that and no more problems. Just a thought on where else you could have the problem. Those connections are known to melt from heat too.

Good luck.

Bulbs that are drawing more that the specified amps will cause the fuse to blow out. Another thing I would try is to disconnect the motors of the headlight assembly and the headlights themselves. Then try to turn the headlights on. If it doesn't blow the fuse, plug one thing at a time and check to see if it blows a fuse. When the fuse does blow out, you'll know what the problem is.

If the fuse blows out with all that disconnected, we can rule those out.

Ok I gave up, I took it to Corvette world in Dallas. They think it may be caused by the tail lights. I have had the LED tails in for over a year with no problems. I have also pulled out the led tail and sent it back to the manufacturer, it tested fine there. Can the tails be the problem?

It is very possible. Anything that is on the light circuit can blow out the fuse.
