Peter requested that we diagnose a problem with his turn signals not working on the right, (passenger) side. Technician drove vehicle into shop, verified complaint. Technician could move the switch around and get the turn signals to work and not work. This is an indication of a faulty switch. New O.E. switch from Buick costs $658.58, aftermarket switch from one of our local vendors costs $524.54. Aftermarket switch from different local vendor costs $323.90, but we have had some problems with this brand of switch and did not recommend. Labor cost to replace switch is $62.37. We do not order parts "online" unless there are no other options. We try to use original equipment parts if possible or aftermarket parts from reputable local vendors. These parts are guaranteed. We are a professional automotive repair facility and cannot provide our services at no charge.
