2005 Corvette AC & Heat control door resembles a vertical blind.

Corvette has some amazing engineering! Who needs real doors to control airflow in the HVAC (Heating Ventilation & Air Conditioning) system, when you can have this material that rolls on spools. This is a masterfully designed system that lasts in most cases until the car is just out of warranty. Kidding aside, if you’re experiencing a problem with your Corvette’s air conditioning, this could be the issue. Codes can be stored and attempts at resetting or calibrating will fail. The weak point is where the material attaches to the spool, on the one pictured it was ripped clean away.

Pinpointing oil, coolant and gas leaks with powder.

OK, maybe Johnson didn’t have this use in mind for their baby powder. But, it can help to pinpoint the origin of leaks. This is particularly true if there’s a leak and the source is not obvious. Baby powder is an inexpensive readily available substance, however it will not change colors when it absorbs fluid like Met-L-Check D70, a leak detection powder that some car manufacturers recommend to help verify automotive fluid leaks. After all a correctly diagnosed leak on the first attempt, saves warranty costs for the dealers.

VW New Beetle rear quarter window regulator kits are available.

In this how to auto blog, we mention the auto tools needed to complete rear quarter window regulator repair on the VW New Beetle. Fair warning though, this job may be too involved for the average DIY (Do It Yourself-er). Labor time in the Mitchell labor guide calls for 2.4 hours each side ( the first time it will probably take longer) for changing the rear quarter window assembly, no extra combination time is listed for installing the repair kit. Getting this job done at the dealer could cost from six to eight hundred dollars, or around two to three hundred for the repair kit installed. Even if you don’t do this job yourself, at least now you know your options.

Recently my brother had a dead battery, so I took my jump box to his house to jump start his car. It’s funny how some things are second nature when you’ve done it a thousand times. He had already tried using his new bargain booster box that he had just bought at a local parts store. The less expensive jump boxes usually only have continuity on one jaw of the cable clamp.
