dash lights flashing on 98 plymouth voyager

hey all, i have a propblem with the lights on the panel where the wipers, and rear defrost,air conditioning are the orange lights that tell you there on, flash constantly. a few days ago the wife left the key in the on position and when i went to go out the battery was dead , when i put it to the off position there was a rapid clicking noise coming from under the dash on the drivers side. so i boosted the van and away i went other than these lights flashing , anybody have any ideas whats causing this. another thing is after youve been driving for a half hour or so they stop, but as soon as you restart the van they start flashing again. thanks fred

Fred,

I had this same thing happen to me after jumping my Voyager a year ago or so.

What has happened is that your HVAC panel has entered diagnostic mode. Here are the steps to go into and out of diagnostic mode manually:

With the engine on set blower motor to high, set mode position knob to panel (i.e. full left), open all A/C outlets, set temperature to cold (both levers if so equipped).

Now press the wash and rear wiper buttons on the A/C panel simultaneously for 5 seconds (until all LED's light). This should get the test started. Assorted lights on this panel will flash as different tests are run. Eventually if the tests are passed the rear wiper LED should be the only light flashing. Push the rear wiper button to exit test mode and you should be home free.

These steps were provide to me by Ron Ginsberg when I had this problem so thanks to Ron for originally posting this fix!

Robert
