Why would your check engine light flash 3 times and stop

SOURCE: flashing lights! dash and headlights

RESET PROCEDURE

With the ignition off, press the TRIP and RESET buttons at the same time you turn on the ignition. HOLD the buttons for 10 sec and the instrument cluster will go into a diagnostic sequence. I dont have the codes but you can find them online (999 means ok).

Doing this procedure will reset the dash cluster which will solve most of the problems.

11= Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking for dodge odb readout. Hope this helps.

SOURCE: Replaced battery, then dash AC amber light flashes on/off.

You could do 2 things...have the codes read and reset at a parts store or try to take both wires off the battery and try to reset the codes.

Sounds like its gone into programming mode. 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 left (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.
