Subject: Re: LG 45 wiper motor amperage/wattage
Thanks Bill for the comments. Yes, I have tried RainX before.
I understand your comments about an old motor and I must admit I am aware of this. On a journey in rain I often check the heat of the motor with my hand under the dashboard !
However if I fitted a PWM and ran the wiper motor at 50% speed for most of the time surely this would mean that the motor would have a much easier time - as the pulses would mean that it was only working half as hard ?
I agree that you would be correct if, by slowing down the motor, I was therefore encouraged to leave the wiper on for longer periods. I dont think I would do this. At present the wipers seem to be quite fast for ordinary rain (I dont think the motor has a problem) . If I could generally slow the wipers by about 25% (and not leave them on longer than at present) then that would surely save some wear on the motor ?
