location of V68? Any ideas?

[LHD_Kid]

Was wondering if anybody knew the location of V68 in the AC system...Its some kind of temperature flap control with potentiometer....
non UK spec 3B old type ACC....
Any ideas? As I don't want to remove the dash, but would like to rectify a fault showing up on diagnostics.....
Thanks

Cheers for that Noel, Unfortunately I reckon it is technically part of the heater, not the AC, and therefore is inside the car, along with maybe the heater controls.... I am guessing behind the glovebox, or around the evap. housing somewhere....
I am trying to avoid removing the dash.....!
Thanks anyway...!

V68 is a (deep breath) temperature regulating flap servo motor with feedback potentiometer - there is a complex procedure for testing it. What code are you getting on diag channel #1 - assuming you know how to get in that mode on the display.

There is also a means of adjusting V68 if its out of whack. To get to it (and check wiring is OK into it) you need to remove the centre sectio of the instrument panel and the front footwell outlets. PITA by looks of it.

Are you seeing faultcode 07, 08 or 15 on the a/c display in channel 1 ?

If so then an adjustment of the pot on V68 might do the trick...
- Remove the control flap motor (V68) keeping it connected to loom
- Set the temp to HIGH
- Start monitoring channel 8 and should see a value of 9-14 in the display
- If not, then adjust the pot with a wee screwdriver until you see a value of 12

If adjustment makes no difference then V68 internals must be duffed.

Hi Paul,
Yes, I am getting fault codes 08 and 15 on the AC display for channel #1.
This is exactly the info I am after, and... damn... it does look like a real PITA to do....
I like the first part of the info for testing.... "remove the control flap motor..."

Thanks for that, will have to go digging and try and test it.....
Cheers
Chris

Is it a sporadic fault or static. If is sporadic doesnt make any sence to bother with it. If is static then you will have to take away the dash because you'll have to change the servo.
