#3952 of 4276 flashing lights on heating and air control assembly
May 16, 2006 (7:00 pm)
The on-off indicator lights on the control assembly of my 1998 dodge caravan are flashing for about 15 minutes every time I start the engine There are four lights that flash the first two and the last two. this started when I put in a new batery. I got a pretty good spark when I connected the terminals and when I turned the key on the lights were flashing. It does not seem to effect anything on the car. I have checked all fuses. please help.

Daniel, I hope you can get a maintenance book for your van and a trustworthy mechanic since some problems are difficult to find the cause without one or the other. To check for spark a timing light is the best tool. The fuel filter is a good thing to change. On fuel injected engines it is under the van to the right rear. Follow the fuel line coming from the tank at the right rear. Roy

You need to get that code(s) when the check engine light is on.
Put your key in the ignition, and without starting the engine follow this sequence within five seconds: ON-OFF-ON-OFF-ON Look at the odometer for the code(s) and write them down. Post them here or go over to Allpar.com and do a search.

... mean that the servo motors for the climate control system need re-calibration. This usually happens aftera loss of power such as a battery change.
There is a sequence that needs to be followed, and is available on Edmunds fora by means of a search.
If, after the re-calibration, the flashing persists, it my mean that the system has failed a cool down test due to low refrigerant, and needs to be checked out further.

I had the same problem and the Dodge House where I lived wanted 500 dollars to fix it! I found someone on the internet who helped me out and I pass this on to you and others to save you some big money as this you can do for free. Here is what you do:
All you need to do is start your van. Then slide your temp lever all the way to full cold. Then turn the Mode Control to the one that sends air to your face only. Then turn the 'blower switch' to all the way to full. Now go to the leftmost three buttons. Press the top one (rear wiper on constant) and the bottom one (rear wiper washer fluid). Hold these two for a few seconds. Once the lights come on solid then begin to flash, you can let go. The AC will now calibrate. You will feel the air blow out of all the different zones at different intervals and see lights come on and go off. Then after a minute or two the top button you pressed will be slowly flashing. This means it has been completed. Press the last flashing button and you are done. Turn off the van and started it back up and see now you don't have those infernal blinking lights anymore! Hope this helps! Oh, be careful with the battery, it is very touchy on Dodge Caravans and can blow out any electrical thing so it is better to take the battery out and charge it and don't charge it directly. One guy mentioned it blew his on board computer just accidently touching the wrench and grounding the battery so be careful with the battery.

I was only able to find code PO700 in the factory and Haynes manuals. It says " An automatic transmission input DTC has been set in the transmission controller" A friend told me it could be a faulty solenoid pack. It might be worth a trip to a dealer just to have the codes read.
