My Lacetti 06 reg, back screen washer operates OK but the front screen washer does not. On operating the stick to turn on front washers no washer motor sounds. Not wanting to get involved in facia panel and steering wheel stick investigation [contact problem] I have taken off the washer motor from under the nearside wheel arch. It seems odd that back works OK but front does not. Any explanations and suggestions would be appreciated.

First step is to check that the fuse for the motor is good. If not replace it. If the fuse is OK disconnect electrical plug from the motor and check for voltage at the pins. If voltage is present the motor is burned out and needs replacing. Most problems of this nature occur where some type of movement takes place such as the motor running, switches being turned on/off, etc.

HiIf the schematics are correct lacetti with front and rear washer uses one motor. It spins the pump in one direction for the front and the opposite direction for the rear washer. The motor should have 3 pins: ground - black wire, front - red wire and rear - green wire. Note the wire colors on the wire harness. Inside the motor is a polarity relay switch. Take the motor out, connect the black wire to negative of the battery and only red to the positive and after that only green to positive. Be careful for short circuits. If the motor spins in both cases and changes direction it is ok. if not it is at fault.

Good luck
