Improved safety and convenience features make the Dodge Caravan a vehicle for families to look at. However, unless you have a 2000 or 2006 or later Dodge Caravan, you can probably count on meeting up with some electrical system problems with this minivan.
Take an inventory of what features stop working when the yellow ABS monitor lights up on your dashboard. You might find the radio, windshield wipers and ventilator fan affected. Try turning off the engine for a few minutes and then turning it back on. If this temporarily resolves the problem, look for a common connection like the front and intelligent modules. If brake lights come on with the ABS light, then the problem may be the power brake booster.
Check your ground connection if the windshield wipers refuse to shut off. Disassemble the grounding stud and clean it up. See if the problem resolves after reassembling. If not, see if your Dodge Caravan mechanic can find fault codes at the body control module (BCM).
Recall whether problems with gauges started after jumping your minivan. The jump may have led to a voltage spike, burning out fuses or the speedometer clusters. Replace burned out fuses. But blame the BCM if gauges quit working otherwise.
Troubleshoot flashing lights at your air regulator and rear wiper delays that work fine at startup, but eventually stop. Look to the air conditioner controller as the problem.
Look for fault codes in your Dodge Caravan computer if your engine loses power while you're driving. If that checks out, check the fuel pump, crank angle sensor, coil pack or loose ground connections.
Replace the speed sensor if you notice electrical problems with the speedometer along with a sluggish transmission upon acceleration. The speed sensor sends a signal to the speedometer. Speedometer problems can also affect cruise control.
Change the engine control module next to the battery if your Dodge Caravan prefers cold weather. When warm weather causes you to lose power while driving, it's sometimes the engine control module. A warmed up engine that doesn't want to shift into all the gears may have a turbo boost electrical system problem.
