Blinking panel button lights

The little yellow lights on my four buttons (AC-air re-circulate-wiper and wiper intermittent) are all blinking continuously. However, it does not seem to effect there ability to function. I have a 1998 Dodge caravan.

That has to do with your computer for your body controls, such a/c, heater, wipers, etc...
Most common problem is drinks spilling into the computer which is right between the cup holder. It will eventually cause a problem with a/c most likely.

This is the Cooldown test mode...... as this happened to mine following a battery replacement.

run the engine for a couple of mins prior to attempting the sequence as the temperature sensor must start off with warm air before it cools the a/c down in this test reset mode.

CALIBRATION/DIAGNOSTICS TEST ENTRY
TO INITIATE TESTS:
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)
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.
COOLDOWN TEST ENTRY


This is a common report after a battery failure/replacement. Somehow your
heating and air conditioning system got into
calibration/diagnostic or test mode, and seem to be indicating a failed
system. Normally this is accomplished by pressing a particular combination
of these buttons and holding for 5 seconds. The tests can run for many
minutes (up to 15) as it checks/calibrates all the motor/actuators and tests
the cooldown ability of the AC.

Results and failures are shows as various combinations of flashing LED's on
these same button lights.

For test abort you can turn ignition off, then on, or the test should abort
after 15 minutes if still not passed. It will however be flashing the
failure code that caused it not to pass within the 15 minutes.

Test mode and failure modes are differentiated by either the LED's flashing
alternately or simultaneously.

Try to run the test purposely to see if it will pass and reset.

Set Blower to HI
Set the Mode to Panel (all the way to the left - CCW)
Set the temperature to full Cold (both slides if dual zone equipped)
Depress and hold the Wash and Wipe buttons simultaneously and hold for 5
seconds (until all LED's light up)

First Wipe and Intermittent LED's should alternately flash during Cal Test
Then after a few minutes AC and Recirc LED's should flash alternately during
cooldown test
If both tests pass - all LED's will go out and that's the end of it.

If it does not pass, then you really either need the manual to use the
buttons and flashing LED codes to dig deeper into the failure codes for
specific components or take it into a shop for them to diagnose and repair.

I have a 1997 plymouth grand voyager. Everything was working fine until my battery died. Replaced battery & now my rear window wiper lights on the dash blink constantly. The wipers work fine when I cut...


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!

it is needing to be calibrated because of dead battery.i cant remember for sure but i think you had to push rear wiper and recirc buttons at the same time and hold them down a couple of seconds. engine has to be running and at normal operating temp. lights will flash and vents will change heat to cold etc. if it fails any test the lights will just keep blinking untill repaired and recalibrated.

The AC and circulation indicator lights are blinking


With engine running and blower motor on, press and hold (for about 5 seconds) the Top and Bottom buttons for the rear wiper controls. All the lights in the ventilation panel buttons will come on, then the top two lights will alternate as it cycles through the blower stages, then all go off. You may need to repeat the procedure a couple of time until the condition finally clears completely.

Lights flash on ac rec and rear wiper buttons. Put on new ac com


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.

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

Flashing lights


Hi, had the same problem today. Solution: Start engine, blower on max, air direction to cabin, press rear wiper and rear wash buttons simulanteously for 5 seconds (all lights now on steady). Calibration test starts and lights flsh alternately. After first test, AC and recurculation lights flash for the cool down test. If all test pass then rear wiper light blinks slowly (press to exit self test). If AC and recurculation test fails then just 2 lights stay on. To repeat this part of the test press just AC and rear wash simulanteously ( may take several attempts and usually best when engine is cold). Again exit by pressing the rear wiper button once it is the only one flashing (slow blink).

This does work but it took me 15 minutes to finally switch them off!!!
