1997 Voyager Problem

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.

Failures flashing LED's can indicate several potentiometers, temp sensors, actuators, control panel etc.

This is happening on mine as well. It is happening because the AC compressor has been removed until I get a new one. How do I just stop the lights from flashing until I get a new one? This just started after the battery was disconnected and replaced.

To: Mike and and group. Thanks for setting me on the right track. It turns out that I have a true A\C system failure. I would assume that there has been a freon leakage over the winter that went unnoticed. I'll follow up after I check it out. Joe (Who) Dionne

It seems that disconnecting/reconnecting/replacing the battery will sometime cause the system test to initiate by itself. If the system does not pass the test, which it may not if you accidentally interrupt it, or by doing other items to the van/can while it is running unknowingly. Sometimes just manually running the test again, by selecting the start test sequence as listed will reset the system. If you do in fact have a failure, it may just continue to act like this, until repairs are made. You could also try initiating the test, and then purposely abort the test mid cycle (after a minute or so) by turning the ignition/van off. Possibly then the test won't auto re-initiate on the next start.

Part of the test is the AC systems ability to 'cool down' a target number of degrees in a specified time limit. with no compressor, or no refrigerant, this will fail. nothing you can do except to try and get the test not to restart on every start up.

My 98 wouldn't "finish" the test unless the blower was on high... I read the instructions given in this group,,, forgot that one,, did it again with the blower on high and the flashing lights disappeared...

That said,, this has happened *every* time I have disconnected the battery in my Voyager, so it's not a maybe thing in my vehicle.
