Hello all,
Today I gave my 99 s70 a little spirited acceleration, really not that much. Here' what occured then:
-Battery warning light clicked on then off.
-ABS, Brake, and what I believe to be the traction control light (looks like swerving car) came on.
-A/C started blowing warm air.

My serpentine is still in place and in good shape.
No blown fuses

I repaired my abs module 4 years ago. perhaps gone bad again?
Maybe my battery or alternator has gone bad?
What do you think?

 

for anyone curious, I disconnected the battery for a few hours, and in my 10 min test drive afterwards, no lights came back on and the A/C blew cold.....that's how it goes sometimes

 

Update: I am currently sitting on the side of the highway immobile. Driving to work,A/C started blowing warm, then lights came back on and I lost all power. Pulled over and shut her down. Now will not start. Waiting on tow truck. Perhaps I have a bad battery or alternator?

 

Maybe not. I can still operate radio and windows...

 

Bad ABS module should not make the car die. Sounds like intermittent loss of battery pwr; bad or loose cable maybe?

Let us know what you find.

 

thanks for the minute update, maybe you can let us know what the problem is/was in case one of us goes through the same nonsense you're having to deal with.

 

You should also consider the ignition switch. Try moving it a bit forward and backward (without going into "start" !!) to see if the lights clear up.
Bad ign switch will cause some strange electrical issues.
