Hi guys I have an issue when I turn the ignition on or start the car the wipers come on every time and they stop after a couple of wipes and then they stop mid way and I have to hold the wiper switch on untill it gets to the start and release the switch plus the intermittent wipers don’t work anymore for some reason and the timer for the intermittent dose not have any response the wipers are eight on or off, I have tried a different wiper switch to no avail also had to put in a 2nd hand stereo and a new battery, check relays and swapped around and no difference checked all relays as well and still no good wipers still come on when I turn the key on all by them selves can anyone advise could it be the wiper motor
