Wipers?'s

[pissonNOS]

if you can believe it we had snow this mornin in MAY thats not the bad part the bad part is that my wipers have never worked properly and i always had to push the knob in then they would wipe put there was no intermittent or anything there is a wire up under the dash that if imove slightly they work fine but this morning i tried to move the snow with my wipers and the wouldnt move then i went and brushed the snow and ice off them then when i tried to wipe there was nothing except for a thumping sound. now I am wondering if I possibly have burnt out the motor or what the hell anyhelp would be good thanks
