1992 Dodge Spirit wipers

Use a test light to see if you have any power at teh motor when turned on, if nothing it could be the switch or the intermittent wiper control module. Check th eback of the switch (dark blue wire) for power then see if it has any power leaving it if so it but nothing at the motor the module is bad, if you have power at the motor and it doesnt work, the motor is most likely the problem
