Minor Issues with Specialty Vehicles You Can Fix Yourself

I. How to eliminate windshield wiper chatter and noise?

Simply use a pair of pliers to slightly tighten the gaps at the wiper arm joints and where the rubber blade is clamped.

II. How to extend the lifespan of light bulbs?

After purchasing a new vehicle—or whenever you replace a bulb—simply wipe the bulb down with rubbing alcohol to remove any fingerprints or oily residue.

III. How to reduce tire noise?

Pick out any small pebbles lodged in the tire treads, and then adhere a layer of black felt or velvet fabric to the inner fender liners of the front wheels.

IV. A simple fix for engine shaking during a cold start in the morning?

This issue is often caused by a specific cylinder misfiring or a valve failing to seal tightly. One solution is to take the vehicle for a drive on the highway (though this consumes fuel); alternatively, you can drive for a while in 3rd or 4th gear at high RPMs (which saves money)—the results are the same.

If the shaking disappears once the engine warms up, but gear shifting remains rough (on a manual transmission), the issue may be uneven fuel delivery from the injectors; these will require inspection and cleaning.

V. How to manually adjust headlight height?

If you find that the in-cabin headlight adjustment controls are not providing the desired beam height, open the hood. You will find a small access hole located above each headlight unit; inside is an internal hex screw (Allen bolt). Simply use the screwdriver included in your vehicle's toolkit to make the necessary adjustments.
