Repair Mistakes & Blunders
Repair  Mistakes & Blunders

Recently I was having trouble starting my 2005 Ford Focus. I pressed down on the clutch and brake pedals, turned the ignition key, but the starter would not crank. Everything else seemed OK, dash lights, radio, etc. I noticed that if I would repeatedly push the clutch pedal, I could get it to eventually start.

So I figured I must have a faulty clutch safety switch. Since it would eventually start, I thought maybe the switch was sticking. I took a look underneath the dash and pressed down on the clutch pedal to see if anything looked wrong with the switch operation. I quickly realized what was wrong.

A couple of weeks ago, my daughter bought new floor mats and was going to throw out her old ones. Instead, I used them in the Focus. I already had an old set of mats, but with a Wisconsin winter on its way, I thought I would just throw her floor mats on top of my old ones for a bit of extra salt and slush protection. The extra thickness was just enough to prevent the switch from fully operating unless I pressed down hard enough to compress the mat. I threw out the older floor mat, leaving just one on the floor. No problem starting now. Thinking back, I started having trouble when I put that second mat down a couple of weeks earlier!

Classic Troubleshooting Techniques
Tom's Story

For years, I have read trade magazines written by and for professional mechanics. I especially enjoy the articles describing difficult-to-diagnose repairs. Symptoms such as an engine failing to start or stalling leads to methodical, meticulous testing of systems and individual parts. The clues often point to an electrical or computer problem. The problem might be intermittent or connecting an OBD scan tool reveals a slew of confusing diagnostic trouble codes.

The technician will often bring out an oscilloscope and start checking the signals from and between computer modules. As I read the painstaking details, I start to worry if what my granddad told me in the 1970s, "These new cars are too complicated to work on." finally has proved true 40+ years later.

After reading lots of articles, I have stopped worrying. The sophisticated electrical testing may help identify the troublesome system, but the specific broken part is often found using classic troubleshooting techniques that have been around since cars were first invented. Techniques such as jiggling connectors, swapping in new parts, cleaning off corroded ground connections and looking for physical damage.

Yes, that BCM (Body Control Module, in "Electrical" category at under that late model GMC truck's seat is high tech, but the layer of corrosion covering it looks a lot like the corrosion that can build up on the battery terminals of a 1960s GMC truck. The IDM (Diesel Fuel Injector Driver Module, found under "Fuel & Air" category at behind the fender liner on that newer Ford truck is sophisticated electronics, but fill it with dirty water and there will be problems similar to those experienced when water gets inside a 1968 Ford Bronco's distributor cap. The trade journal articles have also revealed a rat's teeth can gnaw through important wires on a new car just as easily as wires on an antique car.

A professional mechanic may not get much background information on the vehicle in his/her service bay. A DIYer has the advantage of knowing his/her vehicle's history of repairs/maintenance, modifications (new radio recently installed...) and potential sources of damage (major coffee spill under the front seat...). That information can point out where to start the hunt and turn a difficult-to-diagnose repair into a straightforward repair.

Logan & Cindy's 1981 AMC Spirit
Logan & Cindy's 1981 AMC Spirit

Our 1981 AMC Spirit DL had been sitting outdoors for years when a friend of mine mentioned he had the car and would consider trading it for some wheels and tires I had for sale.

It had been parked in the same spot and had not been started or moved in four years. We went to look at the AMC and brought some fresh gas and a battery booster pack. Once hooked to the charger, and with some fresh fuel, it fired right up and ran incredibly smooth! We let it run for about 10 minutes, then finalized the deal with my friend! But when I attempted to turn the car off and the ignition cylinder would not budge, we then had to get creative on ways to stop the engine.

We got the car home, and with an ignition cylinder, oil, air and fuel filters and some other tune up parts from RockAuto it was running great (and turning off). I spent about a week detailing the interior of the car and polishing the rust free exterior. The paint cleaned up nicely considering the oxidized, dirty mess it was when we dragged it out of the storage yard. We had a blast for the remaining summer months taking it to car shows and just cruising around town.

I shop at RockAuto for all of my auto parts needs and love the savings and excellent service!

Thank you,
Logan and Cindy in Canada
