This Week’s Winners
On this edition of Fix of The Week: lagging wiper blades on a Buick, dimming lights in a Hyundai, and a Fiat that won’t take fuel.
2013 Buick Enclave 328i – Gerry’s Auto Care
This vehicle’s highspeed wiper wasn’t working so we hooked up the scanner to watch the BCM data. We measured the resistance between BCM X5 (brown) pin 21 (tan) and wiper high/lower relay pin 87. We found the wiring harness had rubbed through in the engine bay—the harness comes through the firewall at the passenger side and runs to the fuse box. We found and repaired 3 damaged wires, which can be done without removing the harness if you have small hands and some patience!
2006 Hyundai Azera – Zandees Auto Repair
The Azera’s headlights, radio and dash lights dimmed almost every time when coming to a stop. Sometimes radio would even cut out. We found burned up main ground bolts to the body alongside the battery which looked perfect until we disassembled. Hyundai uses just the threads to ground and there’s no bare metal under the cable end. Also, on the suggestion of a former dealer tech, we ran a 6ga ground to an empty bolt hole on top of the transmission. We checked the cable near the passenger side motor mount and found rust on the threads. Problem solved.
2013 Fiat 500 – Meineke Car Care Center
The customer came in with the complaint that the vehicle couldn’t take fuel. We changed the charcoal canister though that didn’t fix the issue. We then removed all components to the tank and looked for any obstruction and the filler hose and return evap line. What we found was that the fuel pump has a check valve built into it and it was not releasing the air when fueling which caused it to stop. We changed it out with OEM pump—no other option.
