Review on Dorman 937-641: High-Quality Rear Passenger Side Door Lock Actuator Motor for Ford / Mercury Models by Charles Alfian

I bought a 2006 Mercury Mariner AWD and when I got it the horn was off. I put it back in my pocket and the alarm went off randomly and sounded its horn. Traced the actual problem back to the passenger door contact failure and it showed the door open (even though it was still closed and locked). This resulted in the alarm going off and the car being 'fixed' by the previous owner. Ordered a new door actuator, swapped it out in about 45 minutes and now all the doors work fine and now my horn works too. Excellent installation - earned immediately after installation. Is the part worth it?
