power locks auto locking with engine off and blinking lights

[hbill531]

Hi,
I have a 98' Grand Caravan. Had to replace the battery and now the doors keep locking on their own. I can sometimes unlock with the key and before I get a chance to pull the handle, the doors auto lock. I will walk out to the car and hear them clicking every so often. Help!!!

Also the buttons for the rear window wipers, etc will flash for 10 to 15 minutes while driving. Are these problems related? And can you help with this also?

Thanks in advance!

Ok. I have been wondering how to get the same lights to stop flashing for over a year now. I seen this post and read the answer. I immediatly went out and tried it and it re-calibrated the AC so quick I was shocked.
All you need to do is start your van. (if you are unsure what knob or lever is which I am looking in the manual for proper terms) Then slide your temp lever all the way to the right (full cold). Then turn the Mode Control to 'panel' (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 bottn you pressed will be slowly flashing. This means it has been completed (I actually let it run for 5 more minutes just in case something else started blinking). Press the last flashing button and you are done. I then turned off the van and started it back up and now I don't have those infernal blinking lights for the first fifteen minutes of my drives. Thank you to whoever it was who posted the initial answer to this problem.

Hi and thanks for the blinking light fix. But my power locks are still engaging every couple of minutes. The car will be sitting with the power off and the locks click anyway. Any suggestions?
