Rear wiper buttons light flash continually on center console

Put your controls all the way to cold(mine is all the way to left). Turn your blower switch all the way to High. Put the position to console vents(all the way left).Hold down top left button(rear wiper) and bottom left button(rear washer) at the same time until all lights are solid. Then release. Let the buttons flash until only top left(rear wiper) is flashing. Then press top left(rear wiper) to end test.Should help those pesky flashing lights unless there are deeper Problems!

OK got your message on the other post (About the van) I am assuming that your Voyager is equipped with Automatic Climate Control. Follow the instructions below and you will get a better idea of what is wrong with your system.

Calibration/Diagnostics
1. To enter calibration/diagnostics test, set parking brake. Start and warm engine to normal operating temperature. With engine idling, turn blower switch to high. Turn mode switch to panel. Open all outlets. Move temperature to full cold.
2. Press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (Until ALL LEDs illuminate). All LEDs should illuminate for 5 seconds. Rear wiper and intermittent rear wiper button LEDs will flash alternately during calibration/diagnostics test.
3. After approximately 60 seconds, if only the rear wiper button LED is flashing, calibration is successful and the system is okay. If rear wiper and intermittent rear wiper button LEDs are flashing, Diagnostic Trouble Codes (DTCs) are present. (See "Reading Diagnostic Codes" below)
4. To exit calibration/diagnostics test at any time, press the rear window defogger button, rear wiper button, or cycle the ignition off and then on. Test will automatically terminate 15 minutes after calibration/diagnostics is entered.

Reading Diagnostic Codes
1. Perform calibration/diagnostics test. If a DTC is present after calibration/diagnostics test has been performed, system will flash rear wiper and intermittent rear wiper button LEDs in sequence. Rear wiper represents code level, and intermittent rear wiper button LED represents code value.
2. Each time the rear wash button is depressed, rear wiper button LED wil cycle to the next code level in numeric sequence. After code level 5 is reached, rear wiper button LED will cycle back to code level 1. See table below.

push and haold in the rear wiper and rear washer butts for 5sec or until all lights flash but make sure yor 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..

With my 1998 TC you have to start car turn to cold and fan on high. Tehn hold down the rear wiper and WASH buttons until the lights start flashing differently. Let it run through until only the rear wiper light is blinking. You should here it cycling through the different functions. When it is jsut the rear wiper blink press that button and the system is reset if there are no problems. A low voltafge problem had caused mine to act up.

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

This means there are body codes stored in the computer.

It needs a body control module.

a/c control module or a/c relay fuse.

The procedure for re-setting the HVAC control panel on a 1998 Dodge Grand Caravan follows:
With ignition on but not running
1. turn knob to air vents
2. turn fan knob to ON
3. temperature setting on COLD (2X) {I have dual temp controls}
4. hold top(rear wiper) and bottom (rear wiper with wash) buttons pressing down together until all the buttons cycle through (this will require 1 to 2 minutes of continuous pressing)
Hopefully, this also applies to 1997 version. I learned this from a very helpful local Dodge service adviser

the climate control panel has come out of calibration..
to re-calibrate it you need to have
Set Blower motor ON HIGH
Set Mode position to Panel
Open all A/C outlets
Set Temperature to Cold (Both slide pots if equipped)
Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light)

All LED's will turn on for 5 Seconds
When done REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit

your a/c system must be functioning properly for it to re-calibrate.
