My GTA's Auto Wiper function was pathetic
I rarely worked & often far too late, so much so I had to flick up the stalk to operate the 'once-only' function.
So after a short spin in it this afternoon where i discovered that if it gently pushed the Auto sensor towards the windscreen it worked alot better.
Upon arriving back home I tilted the mirror so as I could see the Auto wiper unit, I was surprised to see a 'trap door' at the back of it open & the sensor had slipped downwards within in its casing so as the sensor was almost blocked. There also was a 'jelly' like substance covering the sensor.
I removed this 'jelly' centred the sensor within the casing & closed the 'trap door' Now the Auto function works grand.
One less thing to annoy me.
