A & M Mobile Mechanic, Inc. in Lakeside has dispatched mobile diagnostic units from 12307 Lakeshore Drive since 2000, servicing cars, trucks, diesel rigs, and RVs both at the shop and at customer locations throughout East County San Diego. NAPA AutoCare Center certification backs every parts installation with a nationwide 36-month/36,000-mile warranty, with exhaust fabrication and custom pipe bending subcontracted to Lakeside Muffler & Welding Inc when header work exceeds the mobile toolkit. Fleet accounts cover multi-vehicle scheduling for commercial operators along the Lakeshore Drive corridor near Lindo Lake County Park, with technicians dispatched to job sites across the 92040 zip. Diesel diagnostics address turbo-system troubleshooting, glow-plug circuit testing, and fuel-injector calibration across Ford Power Stroke, Cummins, and Duramax platforms. The RV service program handles slideout mechanisms, leveling-jack hydraulics, and onboard generator maintenance for the recreational-vehicle traffic feeding Rancho Los Coches RV Park on the Hwy 8 Business corridor. Highest-complexity mobile calls include CAN-bus network diagnosis, diesel particulate filter regeneration cycling, and transmission valve-body teardowns on Class A motorhome chassis.
