Hi

I am fitting 3 new Valeo blend motors from Island 4x4 and need a sanity check on the colour coding.

The new ones are coded with tape as follows.
1 has no tape on it at all.
2 wrapped with a green tape 6-8 inches from the motor end.
1 of these 2 has an individual blue tape at each end of the cable.
the other of these 2 has an individual black tape at each end of the cable.

Am I correct in assuming the 2 together (in the green tape) go to the driver side and blue to the top?

I have no idea what the old ones were set up as because I ripped them out months ago.

Cheers
James

The two R/H ones should be taped together. The other one goes to the left. The distribution motor cable simply won't reach the blend flap position on the R/H side. As far as i recall, blue is blend flap, bottom one. Grey is distribution quadrant, top one.

Do not have a grey one.
Blue one reaches to the top easily.

Hmm. I better no power up until I find out for sure. Nothing in Rave.

This is what I have done and it all fits cable length wise.

1 has no tape on it at all to passenger side.
2 wrapped with a green tape 6-8 inches from the motor end to the driver side.
1 of these 2 has an individual blue tape at each end of the cable fits upper or lower.
the other of these 2 has an individual black tape at each end of the cable fits upper or lower.

Forget the above, I swapped so the blue is at the bottom as per the attached photo.
Either motor reaches without too much of a problem.

The general consensus seems to be blue for the blend.

You can only fit them where they go taped together go to right. Other to left. DO NOT power them unless the are in position. If in doubt and right hand will fit at either position. Fit them and power up, see which one moves for blend and which one moves for distribution and change over as needed.

That makes sense.

Yes I have read that powering up with the motors not screwed in place will cause calibration issues.

Thanks

Usually they come with grey, blue, and black (or none) tape on them.

They match up (when you have grey and blue tape) to the colours on the side of the heater box. Grey tape is distribution motor, and matches with the grey cog on the heater box. Blue tape on the blend motor matches up with the blue 'riser' that the RH blend motor bolts to... and then Black tape matches the black lever on the LH side of the heater box (handy to know if you get a second hand set where the 2 RH ones are not taped together!)

In your case, as you don't have grey - then single black is LH Blend, Paired black (with blue) is distribution, and Blue is RH Blend (matches blue on the side of the heater box).

Thanks. So it looks like I have them installed correctly then.
I will try a power up tomorrow.

Right I have powered up and the blend motors work a treat.
The bad news is the distribution flaps do not move.
I think once the casing for the unit is all clipped back together the flaps are still too difficult to turn by hand.
Comparing the friction free action this guy has in his video, my flaps are still too stiff.

Looks like I had better take it apart again and maybe drill out the holes slightly oversized.
All the plastic mating surfaces of the shafts were coated in fresh white grease and seemed ok, but once reassembled it puts too much pressure on the shafts and stops the rotation. Adding the quadrant makes it very difficult to move.

Bu99er.
