My radio, wipers and blinkers all do not work. If

try reprograming key ---if changed ignition was it flashed to vehicle

Please check for codes in the OBD system. Check Battery and Charging System. If no codes perform following test procedure.
Tests/Procedures: 1. Check the Black power connector in the under dash fuse box. Wiggle it with the lights on and see if they malfunction.

2. Wiggle the wiring harness from the ignition switch around the steering column with the lights on and see if they malfunction.

3. Monitor the key on battery voltage from the ignition switch at terminal 3, Red wire at the ignition switch to terminal 3 of connector I/P-E in the under dash fuse box.

4. See if the vehicle has any aftermarket accessories installed that may be tapped into that Red wire from the ignition switch to the fuse box.

Potential Causes With OEM Direct diagrams, components, TSBs, and R&R procedures

Sounds like the key switch has failed.
The fuseable links are on the battery cable and starter.

Ignition key had to insert lately?
Car starts and runs excellent, EXCEPT, when it frequently...
After ignition starts...
A: Brake and Air Bag Lights come on.
B:Tranny SCREAMS only IN park OR neutral.
C: NO A.C or FAN, blinkers, Power windows, radio, mirror motors, YET locks, lights and Engine work EXCELLENT!
SOLUTION: Wiggle forward and back THE IGNITION key!
BAD IGNITION SWITCH!

Check the fuses,and then look at the fusible links,most likely on the starter,if they are good,replace the ignition switch.

Any other strange electrical issues? Headlights, blower, wipers?
Its quite possibly the ignition switch. Just had to replace it on my daughter's 97 jetta. She had first the blinkers behaving erratically, then it was random electrical issues after that. At first we were sure it was in the combination switch, or the arms off the steering column that operate the blinkers, wipers etc. Unfortunately, that change didn't fix it. After a bit more research I learned the ignition switch on these creates these symptoms. Changing the switch wasn't very difficult with a diagram and a bit of experience and the part was only about 30.00.
Hope I've helped -Good luck!

Check for power to your starter relay - if there is power there then most likely is your starter motor

sounds like the accessory side of the ignition switch is not working. When the key is on run position the same wire that is hot coming out when the key is turned to accessory should be hot, along with the ignition wire that runs the engine. (hot meaning it has 12v)

sounds like the ignition itself is worn,go get one from a scrap yard and replace it
