Air conditioning '98 Grand Caravan

[jlonsinger]

I just had my fuel pump, alternator and battery replaced. Even though my air conditioner continues to work properly the lights for the air conditioner and rear wipers are continually flashing. Any help?

Try this: Turn on the blower. Simultaneously push the top and bottom wiper buttons on the left side of the ventilation control panel for 5 seconds. All the lights on the panel will light up. Then two lights on the left side will alternately flash for about two minutes and you'll hear the ventilation modes cycle. When just the top rear wiper light on the left side slowly flashes push that button and you're done. All lights should be out and you should be back to normal. This is the ventilation control calibration test and it resets the ventilation system computer.

Your problem will show up with a weak battery or when it's disconnected. The electronics in these vans are sensitive to voltage fluctuations.
