Hello my name is ***** ***** I'll be happy to assist you today, the windshield wipers and the turn signals are controlled by the Body Control Module, disconnect the left front turn signal bulb and check for 12 volts battery voltage on the yellow wire and ground on the black wire and do the same test on the left rear check for 12 volts battery voltage on the yellow wire if your vehicle is a 4 doors model and check for ground on the black wire, then on the wiper motor check the wiper fuse make sure is good the check for 12 volts battery voltage on the dark green wire and purple wire and check for ground on the black wire if there is no 12 volt battery voltage on any of the wires then you need to check the battery voltage and ground wires on the Body Control Module and you may need a scan tool to check if there is any DTC on the Body Control Module, if the battery voltage and ground wires are good on the Body Control Module and the data comunication line is good then the module need to be replace and program
