Hi,
today I changed the G263 evaporator outlet temperature sender on my A/C to restore the ice cool air.
I did it without taking the dash off. Here is how:
The first task was to locate the sensor. On LHD cars it is on the driver's side above the temperature and windscreen demister flap motors. Although the centre of the climate unit is mostly the same on RHD cars, it turns out that the G263 sensor is on the other side, again on the driver's side. That makes it above the V70 central flap motor.
This picture shows the position of the G263 sensor on the driver's side of the climate unit.
To gain access I removed the trim panel above the pedals.
The central flap motor is flush against a metal bracket which holds the climate unit in position on the driver's side.
This bracket must be moved to the right (towards the clutch pedal) to allow the V70 motor to be unclipped and disengaged.
To do this I removed the 3 bolts indicated in the following photo. The third topmost bolt was removed as it fouled the motor bracket fixing clip.
These were removed using a 10mm ring spanner.
On the lower and rear side of the bracket where it attaches to the side of the climate unit, I loosened the two screws using an 8mm ring spanner. I didn't remove the screws completely as they are very close to the clutch pedal and it would have been difficult to refit them afterwards.
I then pulled the top of the bracket away from the central flap motor, disengaging it from the two pins. The other loosened screws allowed it to hinge in place.
Once the bracket was out of the way, I set up the climate controls to close the footwall and vent airflow flaps. This puts the V70 motor in a position that makes it easy to re-engage on reassembly.
I unplugged the electrical connector and unclipped the wire and moved it out of the way. The motor is attached by two lugs engaged with holes towards the front of the car and a single clip on the back. The clip is released by squeezing the tab and the motor can then be moved away from the side of the climate unit and withdrawn downwards.
The wires to the G263 sensor are clipped onto the top of the V70 motor's fixing bracket. Unfortunately there is no way to access this from underneath to unclip them so I had to pull the motor down hard to break the clip and free the motor. The clip isn't very strong and breaks easily.
This exposes the G263 sensor as shown in this photo. The photo also shows the leavers and pins which travel inside the slots of the V70 motor's drive wheel.
The electrical connector on the G263 sensor was removed by squeezing the release tabs at the wire end of the connector together. Access is difficult so I had to push the bottom tab up with a screwdriver while pulling the top one down with my hand.
Once the connector is out of the way, the sensor comes out easily and is passed through the adjacent hole in the metal bracket. The sensor was then withdrawn and removed past the brake servo actuator rod and down behind the pedals.
The G263 sensor has a bend which should point downwards when fitted.
Reassembly is simply the reverse process.
The new sensor was passed back up behind the pedals and inserted into the climate unit and the electrical connector reattached.
Next and the most difficult bit was to refit the V70 central flap motor. The motor must be put back in place and the two lugs engaged. Doing so however moves the flap leavers so they must be repositioned so that they engage with the correct groves in the drive wheel. The lower lever has to be pushed upwards to close the footwell flaps and the upper leaver pulled down to close the vent flaps. I found I had to hook the top leaver with some wire and pull down hard to get it to engage properly in the groove when clipping the motor back in place. The first time I tried it missed and ended up higher than the wheel which meant that the vents were always open, no-matter what position the motor was in.
Once the V70 motor was correctly in position and the motor's electrical connector attached and wires clipped in position, the metal bracket was moved back into position on the top locating pins and all bolts replaced and screws tightened.
Refitting the trim panels completes the job!
All done, it took 2 1/2 hours to complete. This included some head scratching to find the best way to unplug the connector and also to find something to be used to hook the flap leaver and move it into position.
