Last Wednesday I had my 89 Cutlass Supreme's interior and engine completely steam cleaned and shampoed.
That same day, I had some strange electrical things happen. First, my drivers-side power window did not work at all. Second, my "FASTEN SEAT BELTS" light would light-up full or half-dim sometimes all by itself even though I had my seat belt on. My shock sensor for my alarm would cause the alarm to go off by itself.
Then, on Friday morning, I tried to start the car to go to work and found that the battery was so completely drained that it wouldn't even CLICK or turn-over at all! My digital dash, which normally shows
5-bars for the battery when not running showed NONE! It was that dead...So I got it boosted Friday after work and took it for a 45 minute drive on the highway to get it charged-up. Since then, everything has started to get back to normal. The power window now works fine, the "FASTEN SEAT BELTS" light no longer comes on, and the alarm is working perfectly. Plus, the car started fine every try on Saturday and Sunday. Although on both days I did notice that the voltage wasn't as high as it normally was before the engine was shampoed, especially at idle.
Then, today, going out to go to work AGAIN, the car battery was dead!! Wouldn't even attempt to turn-over it was so drained! It had only been parked for about 15 hours over night. I got it boosted and drove to work, arriving a few minutes late.
Now, I am convinced that SOMETHING is draining the battery when the car is shut off. I believe this is known as a "parasitic drain".
The battery, an Interstate Megatron, and alternator, a GM Delco, are both fairly new, about 1 year old, and both were replaced at the same time. Before Wednesday, I had absolutely NO charging or starting problems, so I know for a fact that the cleaning did something to cause this.
Anyone have any advice or possible solutions?
THANKS!:)
