A customer came in last week stating his blower was not working. After checking the blower circuit we found the blower control amplifier defective and replaced it. As a serivce to our customers we always do a Courtesy Check on all vehicles which includes a 50 point inside and out inspection. We check everything from the head lights, under the hood to under the vehicle and the brakes and tires. We found his tire tread to be below recommended specifications. We notified our customer and he chose to wait on the tire replacement. We phoned him 3 days later to thank him for his service and unfortunately he had a tire blow out 2 days after leaving the shop. Fortunately, he was ok and able to get the repair done quickly and get back on the road. We hate to see this kind of thing happen after someone leaves our shop but it's our job to inform the customer about EVERYTHING that is going on with their vehicle. It's our job and our moral obligation.
