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.

This may sound like an wiring issue but still check the fuses if they are blown. If there are blown fuses found have it replaced. In case the new fuse blows there is likely a short in the wiring you will have to check the wiring. A loose wire or exposed conductor or bad wires may case a short. It is possible that the wire touches the body of the car during vibration so you may not be able to se fuse blowing up quickly.
As for the blinking light, the bulb may be going bad or may have gone bad. It is also possible that they may be affected by the same wiring issue as the other items mentioned.

Not silly, the sometimes put them in obscure places...here is a silly question, it does have a heater grid on the rear window, right? If so, look on the center console, or to the left of the steering wheel for the switch, that is usually where Chrysler hides them.

Testimonial: "Appreciate the help...yes it has a grid, that's what got me looking for a switch....lol. Will give another look-over when I leave work. Thanks!"
A few basic principles for air conditioner troubleshooting. For both central home air conditioner or window air conditioner,
the first thing to check is whether the unit is getting proper power.
If the unit uses 220 volt power be sure that the proper voltage is
getting to the unit. Same for 110 volt units. A voltage meter can be
used to assure that the voltage is correct.
For window air conditioning units the voltage can also be checked before and after the thermostat. If voltage is being supplied to the thermostat but not from it then the thermostat probably needs replaced. This is a fairly common problem. Another place to check is the fan motor voltage. The fan on window air conditioners runs both the indoor blower and the condenser fan. If that motor fails than the compressor may run for a short time, but will overheat and shut off. Continued operation like this will result in compressor failure. This motor can be economically replaced for larger window air conditioners, but for smaller ones the cost of replacement will be more than a new unit.
Central air conditioners for the home are more complex and there are more things that can go wrong. As with the window air conditioner the thermostat can also be a problem. The central air conditioner thermostat will only have 24 volts going to it. So don't look for high voltage there. Some units the voltage will be coming from the outdoor unit and others the voltage will be supplied by the indoor air handler or furnace. Most home central air conditioning will be supplied by the indoor air handler or the furnace. If the air conditioner is for cooling only the unit will usually have only two wires going to the condenser unit. Make sure that you have 24 volts across those wires.
The next thing to check will be the indoor blower. If your thermostat is calling for cooling then the indoor blower should be running. If there is no air moving across the indoor cooling coil then you will soon have a big block of ice formed on the coil. This can happen for a few reasons. The indoor blower is not working, the air flow is restricted and not allowing air to move across the coil. A clogged air filter would also do this. Or the outdoor condenser unit has lost the charge of refrigerant.
Finally and worst of all is when you have a complete compressor failure. Often when this happens the compressor will "lock up" or not be able to turn when power is supplied to it. Overheating or lack of lubrication are usually the main causes of compressor failure. Overheating can be caused by the outdoor coil around the compressor getting clogged with dirt, leaves, or grass. Loss of the refrigerant charge will also cause the compressor to overheat. It is the cool return gas coming back to the compressor that helps to keep it from overheating.
As you can see there are many things that can go wrong with an air conditioner and I have not come close to exhausting the possibilities here. I have just touched on the most common problems in a very basic way.
There are some basic trouble shooting things that can be done very easily. Most problems are above out of the range of comfort for many homeowners and professional help should be consulted before any attempt is made at repairs. Remember also, that the release of refrigerant gases into the atmosphere is a federal offense in the US. Proper care must always be taken to minimize the release of any gases. A license is also required to handle refrigerants. Make sure that the professional you call has the proper certifications to handle refrigerants properly.

SOURCE: Hello, I have replaced the
turn the key on and engine off set the temp on the panel to 75 then push and hold the defrost, floor and mix all at the same time release the buttons when the panel starts to blink, record any numbers that come on the panel and get back with me they will be heater trouble codes but wile this is going on the system will reset all of its componets to the fectory setings.....good luck
get the codes and get back with me.
