The lights on dashboard where the heater is keep blinking. I have 1998 plymouth voyager. It's the buttons for the rear wipers and rear defroster. All those lights keep blinking.

Does it restart? Have you had the alternater tested?

Here's another experts answer for you.

push and hold in the rear wiper and rear washer butts for 5sec or until all lights flash but make sure your motor is warm and that the ac is on high first.. wait until all lights except for the rear wiper light are off then press the rear wiper button once more..

What has most likely happened is that the Heater-a/c unit needs to be recalibrated and here are the steps to do so.
With the engine running and fully warmed up, A/C has to be turned off for at least 5 minutes [don't turn it on at all] and transmission in Park do the following
1. Set the temp control all the way to cold
2. Set the mode selector to Vent so air blows out of the dash panel outlets.
3. Hold down the rear washer button and the rear wiper buttons simultaineously for about 5 seconds until most all of the heater and ac panel lights blink and then release both buttons
6. At this point the system should go into a self calibration test which can take up to 60 seconds. While it is calibrating various control panel switch lights will blink as it goes through it's tests.
7. When the system is done calibrating then just the rear wiper light should be flashing and you can exit the test by turning off the vehicle. Wait about 10 seconds and restart the engine and it should be fine. If both the rear wiper and intermittent light are both still flashing after the calibration then there is most likely a problem with the system that will need more diagnosing. I see this fairly often with battery replacements so I think you'll be ok. It sometimes takes a couple of tries to calibrate so don't give up if it doesn't work the first time. Good luck, hope this helps!

Reset disconnect battery for 5mims.

To Calibrate , start and warm engine to normal operating temp. with engine idling turn blower switch to high, turn mode switch to panel, open all outlets, move temp lever to full cold.
press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (untill all leds illuminate.) all leds should light up for 5 seconds, rear wiper and intermittent rear wiper button leds will flash alternatly during calibration... after 60 seconds if only rear wiper button led is flashing, cal. is complete

Here's what i found is supposed to work.

1. Set blower to HIGH
2. Set mode position to PANEL (AC vent air)
3. Open all AC outlets
4. Temp. on full cold
5. Start engine
6. Push WASH and REAR WIPER switches for 5 seconds until all panel lights are on solid
System will then go through it's paces as it calibrates the climate controls
7. When calibration is complete only the REAR WIPER switch/light should be flashing. Press this switch to extinguish the light
and all should work normally.

have a look at this link, may sure you go far enough to read alternative # 3 solution.

reset your computer, do this by removing thepositive battery cable for 10 mins.......

if this doe snot work, then some thing went bad when the van was jumped.

yes start van..turn blower on high.. set mode to vent .. set temp to coldest.. you have three buttons on the panel for rear wiper press the top one and bottom one at same time hold them until all the panel lights up then release when its done you will have 2 light flashing only if it was successful.. then turn off engihe and restat.. should be back to normal.. but you must have functioning a/c system for it to work

At some point prior to your problem a series of buttons were pushed which caused the activation of the CALIBRATION DIAGNOSTICS AND COOL DOWN TEST"

The test can be aborted by doing the following: 

Depressing Rear Window Defogger, RECIRC and Rear Wiper buttons. 
Cycling Ignition OFF and then ON. 
Control will automatically abort after 15 minutes from the time Calibration Diagnostics and Cool down was entered. 
The HVAC control module will return to normal operation or may indicate unsuccessful Calibration Diagnostics or Cool down test by LED's flashing simultaneously.
