My wife insisted on buying this little Crapalier. The guy selling it was ignorant by choice and too arrogant to read directions. On to the strangeness. The car got new tires and a new serpentine belt and picked up about two miles to the gallon, not bad. Two days ago my daughter and I were driving and I turned on the AC, a warm day in Florida, finally. A smell of burning plastic and wire came through and did not go away, down come the windows and off goes the AC. There had been rain and now was sunny, so all was well with the universe... Until I tried to turn off the lights. The burning was in the switch. My daughter and I got to the new house and left the car on because I could not turn the lights off. When we got home I checked out the Haynes manual and then checked on this site to verify what the book said. I removed the switch and on one of the quick connects there was a clip on the end of a brown wire with a black stripe that was at least twice as big as the black wire in the quick connect that the errant brown/black wire was connected to. I am assuming that the brown/black stripe wire is the AC wire. If not, what is it? To complete the story, the new switch went in and the car runs much better. In fact, fuel economy jumped another two miles to the gallon and the car's brakes function much better due to better vacuum. The old switch had a partial ground and was siphoning off power to ground, leaving the computer and other electrical things a little short in the voltage department. The car used to knock badly and nothing would fix it. As the car is started and stopped, the computer is resetting itself, I guess, do not know. The car gets out of it's own way now and takes much less throttle to take off from a standstill. It is a small car with an anemic engine that cost very little, I do not expect stellar performance, but 26 mpg in and around town, I will keep it, not running the AC until the electrical is sorted out. But it is a weird little car. The moral of the story is this; if you check out "every thing that could have anything to do with the problem" check some other things as well. I would have never guessed a switch and I have read about other people changing out ignition parts and fuel injectors, blindly, hoping to "fix" the problem. Just remove the light switch. If the car runs better, change that. I imagine the wiper switch could do the same thing. Or disconnect other electrical accessories to see if the problem seems better. Wrenches, screw drivers (tools not drinks), and common sense. Loud words, skinned knuckles and the problem solved will save your car from that crushing feeling and be much easier on the pocket book. And you might even feel superior. Back to our regularly scheduled program.
