I have a Grand Caravan. My wife had been using the van and had parked between errands for about 30 minutes and came back out to find that the van would not start. I came home and began to review the situation. With the driver side door open and no keys in the ignition, Relay 13 in the under dash junction box was clicking constantly. Putting the keys in the ignition did not help. Once the key is turned to the start position, nothing happens. With the key set in the on position but not continuing to the start position first, the clicking continues and there are no dash lights, gauges, radio, HVAC CTRL, dome light, head lights, turn signals, horn, etc. The oil indicator is about the only dash light that is on when the key is in the on position ( it is dull like not enough power). The temp and fuel gauge seem to register for about a second with the key turned to the on position and then settle back to baseline. As analysis went on, the problem got worse. The relay started making more of a buzzing/whining noise. When I pulled it, two relays in the under hood PDC started clicking. They were the Low beam relay and park lamp relay. Pulling either one did not stop the other from chattering. Sometimes all three relays would be clicking. If I put the key to the start position and let it settle back to the run position, all clicking stops until I turn the key to the on or off position. If I press the brake pedal, all clicking stops. It starts immediately upon letting off the brake again. The interior light seems to be on sometimes but always dull. At one point (but only once) when I turned the key to the auxillary position (1/4 turn backward) everything internally seemed to get full power. The dome light came on bright, the radio and dash lit up, I heard the HVAC damper open, etc. Can anyone point me int he right direction to start fixing this?
