I have a 2008 Sahara 4 door. I took it to dealership for clockspring factory recall a month ago. After the repair, the horn worked intermittenly, and now a month after the repair the horn, front and rear wipers, washer fluid pump and parking lights would not turn off, even after turning off jeep and removing key. Disconnected the battery twice for 24 hours each time and after the second time disconnecting the battery, the jeep was acting normal. Took it back to dealership and they say it is a bad instrument cluster. I am questioning this diagnosis and also questioning if the clock spring replacement is linked. Thanks for any thoughts.

Hi pfav
Unfortunately the dealership has a point in that the instrument cluster needs coms to the TIPM and PCM. The coms diagnosis is complicated and detailed in the manufacturer's workshop manual. This is available at emanualonline.com for around $20. It's a good buy for hundreds of pages.
The reason the lights and wipers come on is intended to be a safety thing. Your cycling the power to the electronics is correct, in that when you do it once everything may work, but once you turn the key off you will be back to the beginning, and have to cycle the power again.

There should be a Sahara owner who has replaced an instrument cluster and can tell the forum about it.
