SOURCE: 2005 Dodge caravan dashboard indicator lights and dials went haywire
2005 Caravan I had the same problem with my van gauges bounceing, headlights not comeing on when the switch was turned on.I took a day and downloaded a wireing diagram from dodge and studyed it.GROUND PROBLEM dodge have several ground conections to the body then there is one MAIN BODY GROUND.This is most likely your problem it is easy for any back yard mechanic to fix.This main body ground is located under your battery box.You will have to remove the battery and then the battery box becarful of the battery sensor that is mounted in the bottom of the box.Also there is a hose that you will have to disconnect but dont try to remove it from the box remove it from above the box.After you get the battery and box out you will see a threaded stud with a black wire conected to it this will be rusted because of no antioxide grease applyed.You will have to remove the nut and wire connector clean both and the stud with wire brush or sandpaper.Put antioxide grease or if nothing else some vaseline to keep it from coroading again.put back together and see if this dosent fix your problem.It has been six weeks for me now.good luck.dont forget that neg battery terminal is the first one to disconect and the last to reconect.
SOURCE: 2002 caravan, heater problems
That was a common complaint a few years back, due to the fact that the heater core is a little too much higher than the engine, which requires that extra push it gets when engine RPM's increase. One thing I did do on my Caravan was remove my hoses to the heater core, and use a small external pump with hoses to circulate C.L.R. through my core for a while, then let it sit with CLR in the core overnight.Next day I circulated it through again, both ways by reversing hoses, and then re-attached hoses, bled air out of system, and notice quite an improvement in heat at idle. Once cleaned out, the heater core allowed coolant flow through it better at idle. If your stumped by explanation, take it to an automotive shop, or a Rad shop, and get a quote on flushing that core out for you. I recommend the CLR, but it might be too time consuming for you , but a flush will probably show some noticeable improvement.

on my 2004 ram 2500, I had to depress the trip odometer button and turn on the Ignition. all lights on instrument panel will illuminate, continue to hold button in and tach/speedomenter will run full up and back down. once this has completed, the obd codes will be shown in the odometer.
Good Luck

Did you bleed the cooling system after refilling the radiator ? to bleed the system, fill the radiator with water and coolant. Run the engine until it is at a good temperature. Then turn off the engine and look for a bleeding screw at the oulet of the thermostat housing and turn it with a screwdriver counterclock wise. The trapped air will go out and coolant will start coming out. refill the radiator and repeat until only coolant comes out and no air.be careful not to burn yourself.
SOURCE: 97 Dodge Caravan Auto-Shutdown Problem
Been working on my dad's 97 Caravan longer then i can remember for things you mentioned and have been not able to get him to sell it.
I found that the electrical connections are prone to corrosion and have replaced lots of the wire and pin connection in the wire harness, thank god i have time on my hands.
The instrument panel where the wire harness connects, i found that the solder goes bad and i had to re solder the connector on the back side of the circuit board, where the harness goes so you need to remove the instrument panel from the dash,
Here is a link that can help you retrieve DTC codes and do research on your caravan. I'ld tell you everything what i needed to do to keep my dad's caravan running but that would be a novel.

Good luck and keep me posted, glad to help you keep yours running too.
Description
The engine control module (ECM) learns the idle position of the throttle plate to ensure the correct idle. Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position. The idle may be unstable or a DTC may set if the throttle position is not learned.
Conditions for Running the Throttle Learn Procedure
• DTCs P0101, P0102, P0103, P0107, P0108, P0111, P0112, P0113, P0506, and P0507 are not set.
• The engine speed is between 450-4,000 RPM.
• The manifold absolute pressure (MAP) is greater than 5 kPa.
• The mass air flow (MAF) is greater than 2 g/s.
• The ignition 1 voltage is greater than 10 volts.
Throttle Learn
Important: Do NOT perform this procedure if DTCs are set. Refer to Diagnostic Trouble Code
(DTC) List - Vehicle.
1. Start and idle the engine in PARK for 3 minutes.
2. With a scan tool, monitor desired and actual RPM.
3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease.
4. Ignition OFF for 60 seconds.
5. Start and idle the engine in PARK for 3 minutes.
6. After the 3 minute run time the engine should be idling normal.
Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.
* If the engine idle speed has not been learned the vehicle will need to be driven at
speeds above 70 km/h (44 mph) with several decelerations and extended idles.
7. After the drive cycle, the engine should be idling normally.
* If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds
and repeat step 6.
8. Once the engine speed has returned to normal, clear DTCs.
Good Luck
