I'm posting the information below as a courtesy so that anyone who has the above problems might benefit from my experience.

The primary problem -- a/c compressor blowing blower motor fuse when turned on -- is likely due to a defective a/c compressor clutch coil. I emphasize likely because I chose not to repair it. This conclusion is based on a troubleshooting exercise with an Acura expert at justanswer.com.

I decided that it would be imprudent to replace the coil due to the age of the car, compressor, drier, and labor costs. Essentially, given that the compressor is 10 years old, drier 5 years, and that the labor costs of replacing coil are close to replacement of core a/c system (compressor w/clutch, dryer, evaporator) it doesn't make sense to spend an estimated $350 (replace coil only) when $1k for a/c repairs is needed for reliable service (both compressor (working but aged) and drier (should be replaced every 4 to 5 years) are due for replacement).

Pioneer car stereos require both switched and constant power lines to work. Since it appeared that the switched power line failure was due to a defective wire the most practical solution was to use one of the accessory power outlets on the fuse board (under dash). It's a relatively simple procedure to run a wire from the fuse board to the radio. Be sure to use a fuse (see busmann or litel fuse products) for creation of a safe circuit.

The cigarette lighter failure was due to a problem with the spring mechanism within the lighter. My understanding was that the cig and radio were on the same circuit so I assumed that it was without power. In fact, power was and is available for accessory items through this plug.

In conclusion, the above problems apparently were unrelated. So for now, I'll not pull the plug on this car.
