Hey again guys; have another issue on our brand new jeep <400 miles on it. I keep getting the Message in the dash "Blind Spot Alert Temporarily Unavailable" with both mirror indicators illuminating at least once a day, driving down the interstate on the weekend it occurred 3 times about 45 mins apart. The only way to get it to go off is to turn How Does The Turn Signal Work? Turn signals are the flashing lights that indicate whether a vehicle is turning left or right. All cars feature high-mounted turn signals and brake lights. Overall, the turn signal structure and its circuit is standard in most types of vehicle. They often include 3 main parts as follows. Signal circuits This circuit also feeds the Automatic headlamps relay and goes on to the headlamp switch. Start by removing the #6 fuse that is inside the cabin and note any changes. Reinstall Fuse. Next, go under the hood and remove the Auto Headlamp relay that is in the fuse box next to the battery. Note any changes and reinstall. This has been a problem for the past several months. The ETC light would come on several times a week. The dealer replaced the throttle body and throttle position sensor, the powertrain control module, and the gas pedal assembly and sensor. NONE of these repairs fixed the problem. If the cruise control light on dash doesn't work it's the clock spring. You can check this by removing clock spring and doing a conductivity check by putting one probe in on the plug that goes into the switches and the other on the 2 pins on the backside where the 3 pin plug goes.

They have to go back to the same place. Disengage the plastic snap clips and separate the two halves of the steering column cover. Step 2. Electric Park Brake and Fault Indicators. These symbols could be signs of electric parking brake faults. The circle in brackets symbolizes the brakes. If a fault is detected in the brakes, then this sign will switch on. If this light flashes on, you should have the vehicle checked by an authorized dealer. It's amazing that Jeep has not been able to solve this problem since the release of the 2018 JL. We have a 2018 Grand Cherokee with the 3.6L and ESS and it has worked flawlessly since we owned it from day 1. My background: former ASE mechanic and Electrical Engineer. So I am familiar with the technology and know enough to be dangerous. HGI6.
