2005 dodge caravan won't start a relay clicks when turning the key. the gear position indicator lights won't light. the battery is fully charged and the starter has been checked. the dealer installed a new computer but said that didn't help. please help

Flip the pdc over and look for corrison.

OEM is not a specific part. It means original equipment manufacturer. Are you referring to your PCM/ECM? That is the main computer/control module. Is your battery fully charged and charging system working properly? Have you installed any after market equipment or accessories? Automotive electronics can do all sorts of strange stuff when there is a power (battery voltage) problem. A faulty relay is also a possibility.

• Is light switch off and key removed and in "off" position.Worn ignition key switch due to much weight on keyring may damage switch, allowing key to be removed when switch not fully in "off" position.

it is the immobilizer indicator ( red light far right hand corner of dash) it usally means that key is not communicating with computer , try another key ? or if your battery went dead this could cause communacation failure? check your ground to battery and then leave battery disconnected for a few hours , and if there is someone who can scan for codes and wright down any that are there and then clear codes, it can also just be a computer failure that has triggered that light.

Make sure the transmission range selector switch is adjusted correctly it is the switch just below the shift cable post. Also try to start it in Neutral rather than park position.

Possible causes are: 1. Loose or corroded battery cables. 2. Bad starter 3. Dead battery. Try tapping on the starter with a hammer while someone is holding the key in the start position. If it starts then replace the starter. Thanks

alternator bad??? causing a drained battery

This sounds like a classic bad connection either at the battery or engine ground. Check and recheck all your connections and be sure they are clean and tight.

Reset the Dodge PCM - Instructions:

1. Open the hood of the Dodge
   
2. Locate the battery and remove the black-wired negative terminal from the battery.
   
3. Turn the ignition key to the "on/crank" position for 30 seconds, then replace the ignition key to the "off" position.
   
4. Reconnect the negative battery terminal and close the hood.
   
5. Turn the ignition key until the Dodge starts and allow it to idle. Check the dashboard for the malfunction indicator light status.
   

I hope help you. Good luck (remember rated)

No preferences as to charger, as long as it has trickle charge option (slower, but better for battery). Would like to see battery load test done by parts store to see battery condition, but a simple charge may be it. Let me know how it goes, hopefully you will have it up and running soon.
