Short in the ignition?

Sometimes when I start my 99 wrangler everything works fine, but sometimes after it cranks, I notice the radio, wipers and blinkers don't work. If i jiggle the key in the ignition, eventually they will come on. I have been driving down the road, hit the blinker and the radio goes off and blinker does not respond. Obviously these three are linked in the ignition somehow. What do I do to solve the problem?

Exclamation Hello there.

I see you're new here. Welcome! Without trying to sound mean, I'd first suggest using the [Search] feature above and try some of the keywords you entered in your post to see if this question has already been asked and answered. When I did that for you, I found several threads using these keywords which may answer your question (one of them as recently posted in the last 24 hours):

wiggle key

blinkers stop
http://www.wranglerforum.com/f5/some...ers-33657.html

Sounds like either some crud has gotten into your ignition switch, or perhaps things are wearing out, or maybe a connection is loose. The factory service manual is a decent place to start, but to be honest, for something like this, it may just take the guts to crack things open and see for yourself what's happening and possible fixes. As it turns out, I too am having a similar problem, but it's not very frequent, so I haven't bothered to dig into it too much yet, I just wiggle the key a little bit and things start working. But again, searching to see if someone else is having the same problem and already has a fix is a good place to start!

Burned contacts in the ignition switch. Very common problem. When you have it apart, inspect the wiring connector. Any overheated terminals can be cut out of the melted plastic connector body. Cut off the overheated part of the wires, typically about 4". It will be stiff, and solder won't stick to it. Splice in 4" of new wire. You can use crimp-type terminals, but also solder them to the new wire for a better connection.

Check any non factory lights on the vehicle and ensure they are wired through relays. This was a very common cause of burned out switches in the commercial vehicles industry years ago.
