93 caravan - no instrument lights
'93 Grand Caravan. All of the instrument lights went out (dash and
console). All gages are functioning. The instrument dimmer switch still turns on the interior light when moved to the extreme left (or right, whichever it is). The instrument and illumination fuses under the dash check out ok. Where do I look? Could it still be the dimmer switch? The circuit board? I haven't torn the dash apart yet, but I have to believe there's more than 1 bulb to light everything, so I don't think that's it. Coincidentally (or maybe not), at about the same time the fan motor stopped working on all speeds except the highest. TIA, Rick |

Did you check to see if your running (tail and parking) lamps work? The running lamp circuit feeds the instrument lights, a blown running lamp fuse would not allow voltage to the instrument lamp fuse. > Coincidentally (or maybe not), at about the same time the fan motor stopped > working on all speeds except the highest. Possibly a common ground point went open. |

The instrument and illumination fuses under the dash >> check out ok. [ lots snipped ] In addition to the other suggestions, you might wat to try a full power down. In other words, detach the negative battery cable overnight. NOTE: your clock/radio will probably lose its settings. -- __________________________________________________ ___ Knowledge may be power, but communications is the key [to foil spammers, my address has been double rot-13 encoded] |

It is located under the hood on the firewall. If you are standing in front of the van look to the upper left for an electrical connector that looks like it goes into the firewall. This actually connects to the fan resistor. When this thing goes the fan will only operate on high speed. More than likely the connector and resistor are all crumbly and falling apart. Buy a new resistor, but go to the boneyard and clip off the connector from one that looks better then just splice it on to the old wires. I'd use a soldering job and make sure it gets wrapped to be water tight or you'll have a real mess shortly after the repair! Hope this helps. |
