1997 Town & Country LXI Wiper Issues

Suggested Repair

The wiper switch signals the computer, which then controls the wiper motor. Replace the wiper switch first; if the problem remains, the computer may also need replacement. A salvage yard is a practical source for used parts because this repair can be difficult and expensive.

Conversation Summary

A 1997 Town & Country LXI has had worsening wiper problems: the wipers sometimes start on their own, run at inconsistent speeds and patterns in intermittent mode, and now stop wherever they are instead of parking when switched off. The owner asked whether the motor, a sensor, or the switch is at fault. The expert said the computer controls wiper operation, with the switch signaling the computer and the computer signaling the motor. In a similar case, replacing the switch was not enough and the computer also had to be replaced; a salvage yard was recommended for parts.
