Question about 2000 Dodge Caravan
Posted by Anonymous on
Probably is the Body Control Module if you have checked the fuses in the fuse box and none are blown and you have verified power is coming to the wiper and signal switch. One simple fix you can try with the battery disconnected it to unplug and then replug the wriring harness to the BCM that fixed a Chrysler T&C that had the same problem. I also include what someone else gave as advice.
The body control module is located under the dash, directly behind the junction block that contains all the fuses/relays/plugs. The way you could verify that the wiring up to the bcm (from the wiper control) is working, before you go to the expense of replacing it, would be to locate the black plug on the bottom of the bcm (if you look under the junction block/bcm assembly you should see a gray connector and a black connector protruding from the underside of the bcm) and pull that plug, which is the one closer to the cowl. I believe you will find a dark green/yellow wire on pin #7 (from the wiper control) of the plug and a black/light green wire on pin #10 (ground). You may probe those wires with straight pins inserted thru the insulation so as to contact the internal conductor, then replace the plug (but make sure the straight pins don' touch oneanother), turn on the ignition switch to 'run', and measure the voltage between the two pins, you should find that the voltage will change proportionately as you cycle the wiper control through the six different positions of intermittancy. If not, then there is something the matter with the wiper control or its wiring. If the voltage is changing proportionately, then the manual does say to replace the bcm as the solution for that problem.
