Many components stops working when using turn signal.
Sometimes when I use my turn signal (at least) the following components stop working: turn sinal, wiper and radio. One time components stopt working even without using turn signal.
By turning jeep off and on again, all componets works again (crazy). I suspect it has to do with electricity; but what?

Can someone help me?

That sounds like a ground connection is missing somewhere. Have you or someone else done any work on the Jeep where one of its ground wires might not have been reconnected properly?

No one worked on Jeep resently. Do you think the ground is in the turn signal circuit or nearby turn signal switch?

The possible weak/missing ground is more likely to be at or by one of the turn signal sockets. Check the bulbs in all the turn signal bulb sockets as well as the sockets too, bulbs and/or their sockets can cause strange problems too.

No guarantee your problem is caused by a faulty ground but as a guy who has done a lot of electrical/electronic troubleshooting over 50+ years, that is where I'd look first.

Could it be the switch in the key cylinder?
