Hey smart people!

My 2008 JKUS woke up today and front turn signals don't work. Fast click inside told me so. I changed bulbs. Still no good. Checked what I thought was the fuse, maybe wrong on but nothing. Any clues? Maybe if you know which fuse I can look and make sure I was right.

Also have no horn on honk or setting alarm.

Please help me. Thanks.

 

Ugh. Try disconnecting the battery for a few.

 

No luck with battery. Ok. Figured something out. Follow this... 1. Headlight issues where only passenger side works. Both come on, drivers side not as bright and goes out after 10-15 seconds 2. Parking lights on grille don't work 3. Horn not working 4. All started after detailing engine bay Water infiltration? What to do now? No other symptoms.

 

might have disturbed a ground connection while detailing.

 

Any codes? Try the self-test.

 

The turn signals go through a flasher relay. It maybe that.

 

It's actually done electronically by the computer. The clicking you hear is just for the driver--it doesn't control current to the lights as in years past.

OP--Check your TIPM. You might lift it up and check all of the connectors on it. Did you hose down the engine? If so, disconnect each connector and make sure there's no water contamination.

 

Thanks all. Here's an update.

I took off my grille. Tightened grounds. Reinstalled bulbs. Viola! Except headlights, a ballast as per company (rebel off-road hellfire hid) all began to work again.

Drove to daughters school to pick her up. Came out and it worked. Got home and no. Stopped again.

As far as TIPM, what is it and where?

Thanks again.

 

You can see the fuse chart under the lid of the fusebox, if not then google ur year model for info. 1st thing is simply push down on all the fuses and make sure they're all seated properly. This may be common in jk's? Then check the fuses for the alarm/horn.

 

Sorry not just alarm horn, look for your signal/light fuses. My mind was on another issue lol
