ABS problem
 

Hi everyone, (hope I post this in the right forum)

Need your help with ABS problem:

Cold start, rpm's goes up and down to almost stalling low rpm's. ABS light came on and stayed. I waited for a few minutes then rpm's returned to okay level. ABS light remained on and lost power to radio and the express down of window is disabled.

Drove off (don't know if I should have done that :confused: ) and ABS light will go off when I came to a stop then on again when I accelerated. But after about 10 minutes, ABS light went off like nothing happened and I got my radio back but still no express down of window. Then later on after a quick stop and re-starting, express down came back (everything went back to normal)

This happened once last year just before winter and then today. Any idea what went wrong? I checked OVP and the number says it is already replaced by previous owner.

Any suggestion re: what should be checked will be much appreciated.
