#compressorclutch #clutchrelay #paperclip The other day we had a '07 Ford F150 with a battery drain. We did a full diagnostic on the vehicle and noticed a "heavy clicking" sound coming from the air compressor clutch. Some of the reasons why the compressor clutch may not engage are due to mechanical failures, electric failures or low pressure freon levels. We disconnected the battery cable, opened the fuse and relay box to locate the relay for the Air Conditioner. When we pulled the relay, this is what we found. A paperclip, had been added to the fuse as a way of overriding the computer to bypass the relay. For the safety of yourself and others we highly recommend against this method of repair. For one, the factory system is more or less designed to turn off the fuel pump relay in the event of a collision and/or the relay may fail during acceleration on the highwa ... read more
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 t ... read more
#camshaftsensor #aftermarketsensor #mitsubishi Last week we had 2 Mitsubishi's come in, a 2001 Mirage and 2001 Galant. Both would start and then die. Both had previously replaced their camshaft sensors. The camshaft sensor gathers and sends information about the car’s camshaft speed to the car’s electronic control module. This information is received by the computer, which then uses this data to further calculate the time of ignition and the timing of fuel injection required by the engine. This information is vital for engine function. After replacing the camshaft sensor with another after market sensor, results...continued failure. Our next option would be to try the dealership brand, in this case Mitsubishi. The result, in both cases, it worked.
#timingbelt #carmanufacturersrecommendations #interferenceengine The answer to this question should be answered by one of our customers who came in last week. He came in and his car was 15,000 miles over by recommended manufacturers mileage to replace his timing belt. He opted to wait. 2 weeks later he gave us a call. He had been driving on the freeway and the car quit running. Due to him waiting he risked causing engine damage to the cylinder head. This is called an Interference Engine. This is a type of engine in which one or more valves in the fully open position extends into any area that the piston may travel into. This kind of repair is quite costly and significantly more than he would have paid to just replace the timing belt.
#passingsmogcheck #readinessindicators #onboarddiagnostic Technicians are required to perform an OBD II (On-Board Diagnostic) check during the Smog Check inspection. Specifically, the technician visually checks to make sure the warning light is functional, and then the Smog Check test equipment communicates with the on-board computer for fault information. If a fault is currently causing the light to be on, you need to have the malfunctioning component repaired before you can pass the inspection. In Addition, the vehicle stores information known as "readiness indicators" to indicate if the vehicle is ready for an inspection. If too many readiness indicators are "incomplete," the vehicle will fail the inspection because it means that the vehicle has not been operated enough since the on-board memory was last cleared to allow all of the OBD system checks to complete. This can occur if a fault has recently been repaired, or if you have recently had a dea ... read more
#wireharnessrepair #loosewire #problemsolved Today a customer brought in their '08 GMC pick-up complaining of the gauges going to zero and back up again. The previous shop couldn't figure out why this was happening. When this occurs there is a lack of communication between the computer and the gauges. We located the issue behind the stereo. He noticed the wire harness was loose and rubbing against the stereo causing the wires to fray. He also observed insulation on the floor. The technician repaired the harness and then reattached it. Problem solved. Happy customer.
#DMV #brakeandlightinspection #roadtest For the vehicles lights, we make sure they are operating properly. We look for any cracked lenses and check the ABS and brake lights on the dash. We aim the head lights-making sure the adjustors are working. As for the brakes, we remove the wheels, inspect the brake pads, rotors, shoes and drums. We make sure we don't see any signs of leakage in the hydraulic system, this includes the master cylinder, wheel cylinders, calipers, valves, lines & connections. Finally, we do a road test in which the vehicle must be able to stop (panic) in less than 20 feet at a speed of 25mph.
#faultyvanitylight #electricalissues #properdiagnosis Our Electric Lab electrical technician did a diagnosis of the entire electrical system and found a faulty driver's side mirror light in the visor. The flip for the vanity light cover had sprung leaving light on continuously and ultimately draining the battery. Although this problem occurred on a '99 Suburban, electrical drains can happen with most any system in todays vehicles. Having trained technicians and proper diagnostic tools is important to have in an auto service center
#brakepads #brakerepair #heavydutygrade Our technician took the 2005 GMC Yukon for a test drive and verified the noise. He then put the Yukon on the lift and pulled the wheels to examine the brakes. He found that the brake pads were a medium grade brand rather than a heavy duty grade designed for a vehicle of this size. The correct pads were installed after resurfacing the rotors and the technician took the vehicle for a test drive. This time, no noise. That was two weeks ago and we have checked with the customer since and he tells us the brakes are operating without the noise he experinced before. We were pleased to have solved this customer's problem.
#checkenginelight #professionalscantool #diagnostictroublecode Not exactly. What we do have are different tools to use depending on what issue(s) you are having with your car. So for example if your "check engine light" is on this indicates the engine computer has set a Diagnostic Trouble Code (DTC). This usually requires diagnosis with a professional scan tool.
