Dash lights are staying on/van cuts off after start

The 4 wheel drive will stop working, the computer relies on inputs to help your $X$ but as far as I know if its in $X$ the ABS will not work its programmed that way. Check the 4 wheels and make sure your sensors were not cut that usually happens and will light your abs and traction control light on dash.

This is your security system. Your van thought it was being stolen. Next time do not leave your keys in the van and lock the doors.

take it in and have the fault codes read
when engine lights start flashing that is the time that you look immediately to have the codes read

check for earth lead at battery is not broken/

If the battery symbol stays on on your dash, it is the alternator. I had a 91 Astrovan and the light was blinking and then finally stayed on. Talked to a mechanic at Pepboys and he said that was a bad diode in the alternator. Also, make sure that your battery cable is good and clean.

Problems of this nature are usually a loose or broken ground wire. The loose wire jiggles & wiggles around when the vehicle is in motion, thus, the wire touches & untouches producing the blinking dash lights.

Problem #1 The blinking lights in the rear wiper rear defrost area can be reset by holding 2 buttons of the 3 on the left hand side. The top and bottom buttons. Turn the key on and hold them for about 10 sec and they should start flashing differently. Just let it do this. After they start flashing different. It will take 5 to 10 mins. Then one or more will quit flashing all together. If they don't after about 20 min reset them again it can take about 5 trys sometimes before they all go out. Also to fix the dash going out try this. This is a common problem with the voyager,caravans and Town & Countrys. What the problem is is a cold soder in the interment cluster itself. The problem area is where the plug comes from the van into the cluster. You need to take the circuit board out of the cluster and reheat the soder on the back side of the circuit board were the plug plugs into. This will fix the cold soder permanitly I think its about 16 pins you have to reheat with the soder gun. If you don't feel comfrotable doing that you can just replace the interment cluster and it will be fine but if you buy a used one make sure it was tested. This also may fix the ABS light and the airbag light. Hope this helps I have done several of them.

check the bulbs or the sockets for damage
or the wrong bulb
you are getting feedback through the wiring
and that lights up the dash

check the dash lite dimmer switch

It the multi-function lever (turn signal) . When you pull back the handle ,this turns on the high beams headlights and indicator on the dash.
