Have a 97 Dodge Caravan. Changed the battery and now the little lights on the switches for the rear window wiper and other accessaries are flashing. The light on the switch for the rear window deicer is not lit but the deicer is working because you can hear it cause a draw on the alternator when you turn the switch on. Please, any ideas?
de icer?
The reason for these lights flashing is that you had a dead battery or power disconnected for too long and the HVAC control module loses its calibration settings. The way the vehicle let you know this is by making the LED'S blink and drive you crazy until this is taking care of. ---I can help you avoid the Strait Jacket For Calibration of the HVAC control module. With engine at normal operating temperature and running (A/C off): 1) Set BLOWER motor on HIGH 2) Set MODE position to PANEL 3) Open all OUTLETS that air comes out from. 4) Set Temperatures to COLD 5) Press WASH and REAR WIPER button (at the same time) for 5 seconds and release... If the module has completed its test successfully the only LED light that will flash is for the REAR wiper, Push this for a moment and all will be well. -J
