I posted the same problem - little use of car, battery got run down,

Went out Friday night, everything fine, at night, but noticed windows went up and down SLOOOOWLY, parked car next day would not start, but a little light still from headlights.

Fuses all replaced and cleaned 3 yrs ago

Advice so far - going to go to shop tommorow

2 votes voltage regulator;

Battery replaced 11/04 only 8500 miles on car since then

1 vote check charging system, load test on battery (after battery charged)


Vamos a ver, a ver....probable manana
