Check both your connectors on the hardtop harness to make sure the pins on the brown wire with a dark blue stripe are clean and in good shape. This is your park sense wire. If the wiper motor can't tell the TIPM that the motor is in the park position, it will keep running. It may also set a diagnostic trouble code.
To get any fault codes, plug in the connector so the wiper is running, then use the following procedure:
1. To check your Jeep JK Wrangler’s DTC codes, simply insert your key into the ignition, turn it to the ‘ON’ position but do not start the engine. Then, push the key into the ignition cylinder and while holding it in, turn it to the ‘OFF’ position and then back to the ‘ON’ position (3) times straight making sure to end with it in the ‘ON’ position. It is important to keep pushing in on the key to prevent it from catching at the different positions along the way.
2. If you do step #1 correctly, all your dash lights will illuminate and your odometer will show up as a series of (6) dashes If your Jeep JK Wrangler has any logged in any DTC’s, they will be displayed soon after the dashes appear.
Write down any codes you may have so we will know where to get started. anything relating to the horn or wipers will be a fault code that starts with 'B' for body.
I also need to know if the wiper stops when you pull the M24 fuse.
