Recently I purchased a 08 wrangler unlimited and when I crank it up the wipers come on and the lights wont turn on also the turn signals wont work either. Could this be the TIPM? If so will a tipm from any Jeep, dodge or Chrysler wont in mine?

Disconnect the negative battery terminal for about 5 minutes and then reconnect it. Make sure that the 10 mm nuts that release the clamps do not have any wire terminals connected to them.

The symptoms you describe could be a voltage issue (loose connection, battery going bad, etc) or the TIPM. The disconnect should reset the TIPM and if it's simply a computer glitch, it will go away. You need a Wrangler specific TIPM, not anyone will do. It also has to be the right generation. A TIPM from a 12 may not work in a 08. If you go the TIPM route, buy one based on the part number of yours.

TiPM / Clock Sping Multifuntion

OK lost my headlights, Wipers and Signals and dome light. Pulled TIPM sent to TIPM rebuilders , The found nothing wrong with TIPM, Replaced Multifunction switch, still no success, replaced wiper switch, still nothing,
replaced clock spring. still nothing. Disconnected battery numerous times. Re-seated TIPM connections numerous times. ocationally things will work for short period of time.

When I disconnect the multifunction switch headlights an wiper are on constantly.

Any help as what to try next on my 2008 JKU rubicon

Makes me wonder if your stereo is wired correctly, and or backfeeding through a ground, especially if it doesn't think its connected
