on a sierra the screen is in "2 halfs" if u get me...check to make sure the wires under the scuttle panel are earthed and check if they are soldered to the screen as they are quite weak..if they are ok then the screen is donald ducked...if u need a screen contact me or ask big ern and i will do u a good deal..that is if u dont go through insurance....hope this isnt breakin forum rules by the way
