2005 GC electric door window problem

Hi. My Cavavan has about 120,000 miles. Trouble with operating the left door window started about a year ago and was intermittent. Permanent now. I remedied a similar problem on a Camry by adjusting the cable feed from the car body to the door. I think that problem was caused by a lot of flexing from opening and closing the door. Have given this a try on the Dodge but does not cure the problem. A broken wire inside the conduit? Thanks

How'd I miss this one? Power sliding door or the driver's door? If it's a sliding door yes, take a look at the wire harness inside the articulated conduit at the bottom of the door. Driver's door? I would suspect the motor. Hold the switch up or down then slam the door shut. Sometimes brings them back to life.
