My 2006 Jeep commander wont start. It is doing all kinds of funny stuff. When I try to start it all the dash lights start flashing and wont do any thing and the battery is fully charged. What could it be?

Need more info, is your light on on the dash? Are the brakes working fine?

Have you tried locking the drivers door and then unlocking it with the key?

Sounds like a stuck relay.

Under the dash board on your driver side there is a wire with a button turn the ignition but don't turn it on and hold the button on the wire till u get a steady light.. Deactivated

It is probally the check engine light, If it stays on while you are driving,It should be scran before you have serious trouble with it,

Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

The problem is likley caused by a defective brake light switch, it is located under the dash above the brake pedal arm, you must remove any under dash covers to see it.

It cant hurt to check your spare. It may need a bit more air.

you may have a problem with the headlight switch or the dimmer switch.

not a battery problem if you could still drive it with lights off,but you do have a loose connection some where,can't tell you why your battery went dead 2 nights ago
