Flash for pass was the only headlights working

A local technician I know had a problem with head lights only working in the “flash for pass” position on a 2003 Mazda 6. There were no running lights, no low beam or high beams. This was puzzling, at least the high beam bulbs were good and it wasn’t really possible for all the exterior lights to have bad bulbs. After checking all the usual things like the fuses in the passenger compartment fuse panel and the one under the hood and switching a few of the relays to see if anything would happen… nothing. The high beam indicator on the dash DID light up indicating that the switch was doing something and the switch felt normal; sometimes on cars if a switch feels funny, loose or worn that would be an indication of a problem.

Brake bleeding sequence; right rear, left rear, right front and then left front

Brake bleeding is necessary when a system has been opened or the brake fluid has been allowed to get too low in the master cylinder. Air can enter due to a low master cylinder caused from a leaky wheel cylinder or other brake component. If a hydraulic part like a wheel cylinder, caliper or brake line has been replaced the system will need to be bled. Brake bleeding at the wheels can be done several different ways. The most common way is old fashioned manual brake bleeding.

Get your A/C checked at a local shop or check it yourself? Freon will need to be added by someone.

Summary ©DenLorsTools.com: Adding Freon or topping off a cars A/C system is the most common task performed to restore performance and get cold air blowing again. However, adding refrigerant isn’t always the solution for car air conditioning problems and troubleshooting may be required before just charging a car AC system.

2003 Sebring Convertible rear quarter window regulator failed.

© DenLorsTools.com Summary: Chrysler Sebring convertibles have a common problem of rear quarter power window regulators failing. The window will typically stop 1/2 or 3/4’s of the way up at the worst possible moment  – i.e. when the the convertible top and windows are going up due to a torrential downpour! Kidding aside the rear windows on these cars do have a lot of problems. Sebring quarter windows may not fail as often as the New Beetle windows we blogged about previously. But like the Beetle, the Sebring has a particular weak point in the quarter window regulator, they were either designed horribly… or were designed to last until out of warranty, I’m not sure which. As the picture shows above, the pulley has grooves that keeps the cable separated.

Flooded in the driveway is a real problem, not so unfamiliar to RX8 owners.

Summary: Mazda RX8 is a great sports car with a bad flooding problem (cold starting problems as well). The Rotary engine tends to be flooded very easily if the car is turned off before the engine fully reaches operating temperature. This happens typically when the car is started up and only moved a short distance. There was a recall to recalibrate the PCM, plus a revised leading spark plug number mentioned in this TSB, however the problem still persists in some cars that have had theses updates. Reduced starter life and damaged catalytic converters are a few of the casualties brought on by this car’s flooding problem.

Heli coils are used in many applications when threads are damaged, but what happens if you need to remove one? If the depth of the threads is too long or not long enough there could be a need to remove the Helicoil and install one with the correct length. Also if the threads are rough or you’ve found a better insert to install, removing the Heli-Coil insert could be an obstacle.

Jeep Cherokee and Grand Cherokee differentials seem to have the highest failure rate compared to other makes and models. I’ve found this to be true in my years working as a master auto technician. Many technicians shy away from rebuilding rear ends even though they are quite accomplished otherwise. The actual R&R of the parts isn’t really that hard…it’s setting the rear end up so that there is no noises when your done.

Cam solenoid is missing screen at X position

© DenLorsTools.com Summary: Many Chevrolet Colorado and GMC Canyon pick ups are having problems with P0014 and/or P0017 codes. This has to do with the correlation of the camshaft and crankshaft as the computer sees them. Idle can be affected and the vehicle can even stall. The culprit is almost always the camshaft actuator solenoid valve, not the crankshaft position sensor or a cam position sensor. There have been reports of rough idle and fluctuation as well. The solenoid affects the variable cam timing control. One of the tiny screens can wear and be disintegrated causing everything to go awry.

Car cranks over but doesn’t start.

OK, so you don’t have a Model T like in the picture but all your car does is crank over and does NOT start. I’ve been writing some articles geared more for the weekend mechanic and publishing them on a different site. Since this auto repair blog is mainly for professional technicians, I generally don’t post the more basic auto repair tips and tricks articles here. But I realize that not everyone that reads this blog is a professional tech, so I wanted to provide this link to one of my articles I originally posted at EzineArticles.com.

Expedition body is raised for easier cylinder head removal.

Summary: If removing a cylinder head on an Expedition or Navigator, many professional technicians will do a “Body Off” procedure which makes the engine much more accessible. Although this appears to be over dramatic and an over-kill, it really doesn’t take that long to raise the body once you know what to do. Flat rate technicians make their money by getting the job done in the shortest period of time. And if that means seemingly going to extremes, so be it! Find out how to avoid going through all this trouble for a failed helicoil, by clicking here.
