Got back from the service center and well, the situation is as clear as mud.
They put the battery on the tester and they say it's okay. 12.67 volts, 781 amps, passed the temperature test. So they refused to give me a new one under warranty.
They said it's normal to see a few drops of acid on top. Say what? Is this true or bull?
I am not convinced myself as the battery won't go past 90% on the charger.
I also didn't get a fan relay as they don't stock these but at this point who knows if the relay is indeed bad or if the blower fan running while the car is off is really a symptom of something else.
As for the car itself, it runs fine on the road. However:
- The airbag light that stayed on yesterday is off now when the car is running. I still get beeping once in a while though.
- The ABS and oil light still come on dimly when the car is off; they go out when it is running.
- In the parking light at the service center I heard a clicking noise under the dash behind the glove box. It's intermittent and the clicking seems to occur at the same time the speedometer twitches.
- I put the fan relay back in and sure enough the fan came on though the car isn't running. So I pulled it.
Anyway, I'm stumped, worried, and really fed up. I guess I'll have to sink some money into having a mechanic figure it out. I'm no good at trying to figure out if there's a short somewhere.
I will look up info on TRS problems & side effects though.
