When I start the car the windshield wipers come on without the wiper switch being turned on. They eventually cut off after about five minutes.

Hi and thanks for using 2CarPros.

First, there has to be a short to power for this to happen. Most often times, it is in the switch itself. Here are the directions for testing the switch. It will require electrical testing. The attached picture correlates with these directions.

1. On models equipped with radio coded theft protection system, refer to Vehicle Damage Warnings for system disarming and arming procedures. On models equipped with airbag system, refer to Technician Safety Information for system disarming and arming procedures.
2. Remove instrument panel lower panel and knee bolster.
3. Disconnect connectors from main wiring harness.

4. Check for continuity between terminals in each switch position according to table, Fig. 6 (picture 1). Replace switch as necessary.
5. On models equipped with radio coded theft protection system, refer to Vehicle Damage Warnings for system disarming and arming procedures. On models equipped with airbag system, refer to Technician Safety Information for system disarming and arming procedures.
