Today I was trying to figure out why power windows work slow and this is what happened. I connected vehicle to battery charger set at 40 amps to see if windows would go faster. (trying to determain if it was battery issues) I observed no change in speed so I tried it on I think it was 150 or 200 amps. It was at this time the windows and radio stopped working. (possibly other things just not sure) I disconnected the charger and returned to the drivers door and the radio came back on (clock was wrong time) and the windows began to work again. (still very slow) So I was wondering 1) is there some sort of auto rest breaker that tripped and reset and or could I have damage something even though everything works again. 2) any ideas about the slow power windows??? Any help or ideas would be great
