Why won't my Dodge Grand Caravan power sliding door open or close?

Short answer: On the Grand Caravan, a power sliding door that stops at the same spot, bounces back open, or won't respond at all is very often a broken wire in the flexible wiring harness that runs along the lower track between the door and the body. The wires flex every time the door moves and eventually crack inside the loom. If the door slides freely by hand, start with the harness before you buy a motor.

Symptom: The door opens partway and stops at the same point, closes almost all the way and pops back open, makes the unlock sound but doesn't move, or works only by hand.

What to check first

1. Try the door by hand. If it slides smoothly, the problem is more likely electrical. If it's stiff, check the rollers and track first.
2. Inspect the flexible wiring harness in the lower track where it bends. Owners say the break is often hidden inside the loom. Gently tug each wire.
3. If one door works and the other doesn't, compare them. Owners swap or compare harnesses to confirm.
4. Check the power door switch in the overhead console and the door's on/off switch.
5. Run your VIN for recalls, including 10V235 on some 2008–2009 vans with a misrouted harness near the lower sliding door hinge bracket.

Likely causes

1. Broken wire in the sliding door wiring harness. The harness flexes in the lower track every time the door moves. A cracked wire stops the door at the same point or keeps it from working.
2. Failed door motor or drive cable. If the door is hard to move by hand, the motor or cable may be binding.
3. Door module or settings. Some cases need a scan tool to check the door module and run a relearn.

What it usually costs

On the Chrysler Minivan Fan Club, a 2009 Grand Caravan owner said the dealer wanted $209 plus tax for the driver-side harness (part 68043333AB). He found it online for about $120 to $160, and another owner bought one on eBay for $129 shipped and installed it himself. Owners of earlier vans on DodgeForum mentioned a dealer estimate of $750 to replace both harness and motor when only the harness was bad, so get a diagnosis before buying a motor.

Is it safe to keep driving?

A door that won't open is an inconvenience, but a door that won't latch fully closed isn't safe to drive with, especially with kids in back. Make sure the door is fully latched before driving. If the door misbehaves and the battery keeps dying overnight, get it looked at soon, since a stuck motor or shorted harness can drain it. Verify with a mechanic.

DIY or shop?

DIY-friendly for a harness swap: owners remove the step plate, lower B-pillar trim and roller arm cover, unplug both ends and swap it in an hour or two. Shop for motor, cable or module work.

Recalls, bulletins and complaints in plain words

• Recall 10V235 (certain 2008–2009 Grand Caravan and Town & Country built February 2007 through September 2009): some vans have a misrouted wire harness that the lower sliding door hinge bracket can rub through. That could short inside the sliding door, overheat the latch and possibly start a fire. Dealers repair it. If your van is part of this recall, the dealer fixes it for free.

What owners report

• In 2009 Dodge Grand Caravan Sliding door harness on the Chrysler Minivan Fan Club, an owner's driver-side door kept stopping at about 95% closed, then jammed, and the van's battery was dead the next morning. He opened the plastic track and found two wires completely separated. Another owner replaced the same harness himself and the door, and its window, worked again. One member said his van's harness had been replaced under the recall.
• In Automatic Sliding door wiring harness/instructions on replacement?, a member explained that the usual cause is broken wires inside the plastic chain guide, within a few inches of the bend nearest the door roller arm, and listed the steps: step plate cover, lower B-pillar trim, the gear cover on the lower roller arm, then the connectors and clips.
• In Power sliding door issue... help!! on DodgeForum, owners of earlier-generation Caravans with the same kind of flexing harness found doors that stopped about 6 inches from closing. One tested each wire for continuity while sliding the door and found the break, and a parts counter told another owner they stocked lots of harnesses but not motors.

My take

My advice as a former lot tech: I cycle both power sliding doors five or six times on every minivan I check. A door that hesitates at the same spot is almost always the harness. It's a cheap fix, but I still use it to knock a little off the price.

Vehicle focus: 2008–2016 Dodge Grand Caravan (also Chrysler Town & Country) with power sliding doors.

Safety / mechanic note

Make sure the sliding door is fully latched before driving. Verify with a mechanic.
