Intermitent starting problems, 2004 Jeep Grand Cherokee sometimes won't start, gauges move, but no dash lights come on, I wiggle the key and try it again and most of the time it will start. I had the ignition switch replaced, the battery tested and connections cleaned, still acting up. The only light that comes on in the vehicle is the light on the recirculating air control on the climate control system. Any ideas?

You will need to remove the cluster and make sure you plugged in all the connector to the cluster, the antitheft system runs throught the cluster also and you said fuel gauge doesnt work so i would have to say theres a bad connection or you forgot to plug a connector in. good day.
typical jeep gremlins on a 17 year old car
mechanics either replace all the computers and modules
or throw lots of unnecessary parts into it with minimal results
needs a volt meter an LED test lamp and a lot of time
tracing the wiring faults
starting at the battery through to the ECU and ignition
THIS INDICATOR IS FOR YOUR IMMOBILIZER SYSTEM..TRY ANOTHER IGNITION KEY WHEN STARTING VEHICLE..IF YOU HAVE ONE..THE KEY YOU ARE USING MAY BE FAULTY..THEY HAVE A TRANSPONDER CHIP IN KEY..THE DEALER WILL HAVE TO CUT YOU A NEW KEY IF YOUR'S IS BAD..THERE IS A SECURITY CODE FOR YOUR VEHICLE ONLY AVAILABLE THRU THEM..I HOPE THIS HELPS
It takes very little voltage and amperage to operate dash gauges. You cannot rely on "seems" when it comes to the battery. A good battery should have standing voltage of at least 12v and be able to "snap back" from a fifteen second 200 amp load. Under load, the voltage should not drop lower than 9.5 volts. Have the battery charged and load tested before going anywhere else with this. then make sure connections are clean and tight. After you get it started, if battery was good, check starter draw and charging system operation. If it does not start, check power flow from key through neutral safety switch and starter relay to starter.
loosen up the ground cable at the body and on the block to where you can just move it and wiggle back and fourth then retighten also you will see a black wire comming off the positive of the battery unplug it and plug back in make sure it has a good connection. also seen bad factory terminals cut off and replace
Poor grounding can cause many of the conditions you have listed. When checking power with a volt meter, this goes unnoticed because the meter does not draw enough amperage to cause the bad connection to break contact. Your battery is grounded to the engine block and also has a small lead to the fender. Many components have individual ground leads as well (including most computers) I would check all ground leads and clean the contact surfaces with sandpaper or a wire brush. Adding an additional ground wire is a good idea as well. Don't forget that the dash board frame must also provide a good ground as well. Many times this is all you need to do...sometimes though, control modules can be damaged because in having a partial ground, they build up heat, due to additional resistance in the circut. This may or may not cure your problem, but it's worth checking out. Grounding is often overlooked, especially if it has not completely broken down.
