The retractor is mechanical. There's no sensors involved. If there is no hint of the belt trying to go back in, that would suggest the spring is broken. That would be very uncommon but would require replacement of the entire unit. A trip to the salvage yard would be in order. Or, something fell inside and is blocking the mechanism.
If the belt is just sluggish and will go back in with a little help, spray the belt and the top anchor the belt goes through with Silicone Spray Lube. You can get it by that name at the Chrysler dealer's parts department, or other auto parts stores. It sprays on like water, then evaporates quickly but leaves a bunch of "slippery" behind. I have to do this to my '88 Grand Caravan about once every other year.
