Hi Ron, I'm glad to assist you. No, this would just be the door lock actuator only. The door ajar switch is sold separately. But, we do not carry the door ajar switch, unfortunately.

No

Hi Gunmar, This part may fix that ticking sound and lock problem for the front passenger side. I could not confirm the fitment since I do not have the complete vehicle information to work on (no year). To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

It eliminated the sounds my truck door was making and now my vehicle is secure

Hi Danny, I'm glad to assist you. Yes. This will fix a defective door lock actuator on the front passenger side. If your actuator is not functioning and emits a clicking sound, this will fix the problem. You have to remove the interior door handle, the door panel trim, the plastic insulation of the door in between the door shell and door panel trim. You can purchase the Chilton repair manual we have for your car to see the install guide. This is with part number 28200.

Hi, This will not fit, the fitment details say-"Without Anti-Theft System". Unfortunately, we do not list the one with anti theft function which is the correct part that you need since you have the passlock security system.
