2004 wrangler unlimited wont start after driving on salty winter roads.

Can be in areas with salty roads in the winter. Have you cleaned the ground connections good ?

Thats normally a sign of bad connection on battery terminals friend.

Try undoing them and taking them apart to clean up the battery posts and cable connectors then reconnect tightly.

What happens is the bad connection wont let a LARGE current throgh, So when you turn the key, all you are hearing is the little solenoid trying to send large current to the starter motor which is not happening.

It is a simple and VERY cheap job.

by your description, it sounds like you may have a starter problem. The main wire from the battery may be loose on the starter end.as well. If you do any off roading this would be typical as well as corrosion. There is an ignition relay as well, and a fuse for the ignition. This I believe may be under the hood in a plastic box. I would check fuses first, then have a look at the starter and wires. Starters are known to go without warning. If this jeep is a manual transmission, I would try to start it by coasting and catching it in gear. If the jeep starts, it is in the starter,or wiring. Ground wire included. if not, the problem lies elsewhere. keep me posted

Im having this same problem with my 2007 Jeep unlimited. New battery but about once a week it dies and I have to get it jumped! Have no clue what it can be! Can someone help!!!

sounds like the solinoid in the starter, if it is a stick shift try to jump start it

Yes! Another area to check is the wiring at the Starter Solenoid and to the Starter itself. You don't mention how many miles are on your vehicle. Many Starters fail at High Mileage when most of the driving has been Short Haul. The Starter is typically good to somewhere over 100K Miles for normal driving usage. Short Haul, many starts, reduces overall life of the Starter. Winter driving where Salt is used on the roads can cause corrosion on these critical connections too. Carefully Inspect each termination from Battery to the Starter and Ground cable connections too. Not to mention the Starter Mounting Bolts.

Nuetral safty switch, Starter solenoid.
Do you have antitheft?
The ground for the starter relay may be computer controlled. Lee

clean and tighten battery connections, starter connections and ground.

Solenoid on starter needs to be replaced. faulty thats where the clicking noise came from..

Check the Starter Solenoid mounted near the battery.Check it out in the dark...have someone try to start it and see if it sparks at the solenoid.connections may be loose.Also check/wiggle wiring harness to starter.
