Speedo and tack lights dont work on 1998 v6 3.3 dodge caravan replace all fuses and lights instrument cluster looks ok ?


This is most likely in the cluster. It may have replacable bulbs in the back of it. If it does not, than it is a sealed system and the cluster needs to be replaced. Good news is you can put a used cluster in this van and you will not lose your miles.

The lights controls of rear wiper switch is flasher


My 97 Voyager has done the same thing. It was control panel programing, the following instructions is how to program your control panel: 1) SET BLOWER ON HIGH 2) SET MODE TO PANEL 3) SET TEMP TO COLD 4) PRESS WASH AND REAR WIPER TOGATHER AND HOLD FOR 5 SEC. IT WILL GO THROUGH A SERIES OF FLASHING, WHEN DONE THE REAR WIPER SHOULD BE THE ONLY ONE FLASHING PRESS REAR WIPER TO EXIT. DO THIS WITH VAN RUNNING. This worked for my 1997 Voyager. I hope it works for yours.

Changed batteryand now the hvac lites are on


You need to recalibrate the climate control system.
  • Start the van.
  • Slide the temperature lever all the way to the left (full cold).
  • Turn the Mode Control to 'panel' (the one that sends air to your face only).
  • Turn the 'blower switch' to all the way to full.
  • Now go to the leftmost three buttons. Press and hold the top one (rear wiper on constant) and the bottom one (rear wiper washer fluid) until the lights come on solid then begin to flash, and then 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 button you pressed will be slowly flashing. This means it has been completed.
  • Press the last flashing button and you are done.

1998 dodge caravan. AC problem. My AC doesnt work, the lights on the dash are blinking. I took the Van to C-Tire to get the AC recharged as the AC clutch was not turn when the van is running. C-tire did a...


do this calibration reset, it will usually rest he lights and the ac will work again, if it doesn't reset you have a part failure and the dealer you need to hook a Chrysler scan tool to diagnose the problem.

CALIBRATION/DIAGNOSTICS TEST ENTRY
TO INITIATE TESTS:
Set Blower motor ON HIGH
Set Mode position to Panel
Set Temperature to Cold (Both slide pots if equipped)
Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light)
RESULTS:
All LED's will turn on for 5 Seconds
Calibration Test is running when REAR WIPER and INTERMITTENT are alternately flashing. Cooldown test is running if A/C and RECIRC are alternately flashing.
Acceptable results is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit.
After all tests have passed, Calibration Diagnostics and Cooldown can be run separately

AC & Rear wiper switch button indicator lights blink


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)
I learned this from a very helpful local Dodge service adviser
