Look ... bit late for that

Both have helped 1000s on here over the years. Forgotten more than we will ever know

ABSOLUTELY... same with Mozz and, no doubt, several other's I'm not even aware of.

Great entertainment and you learn loads.
Whats not to like?

So how does that help ANYONE, Wammers?

I will allow you to work that out for yourself. Why did Colin supply me with a Nanocom before they went on sale to the public?

Colin would be the man to ask that question, Wammers. Regarding the "tit-for-tat" discussion yesterday between you and Keith, what was constructive for the forumites on here?

When someone, no matter who it is, posts something misguided i reserve the right to correct it. You would do well to realise just who some of your heros contact when THEY have a problem. However i will not expand on that comment. Now be a good lad and stop stirring the crap.

Not "stirring" anything..."crap" or otherwise.

Let it drop there's a good fellow.

Happy to "drop it", but don't appreciate the patronising tone.
Don't have any of the "hero's" you referred to in an earlier post, other than Mozz who, incidentlally says you're a good guy on here...and a fellow Lanc!

OK do it then.

Thought I'd attack the drivers side blend motor again, don't have the courage to look at the passenger side yet.
It's still not happy but not giving any fault code either! Ignition on it cycles fully cold to fully hot, then refuses to budge until i turn the ignition off and back on at which point out repeats the cold/hot cycle. Calibration maybe?
If it was getting an unexpected reading from the pot, surely I'd get a fault code?
I'm getting codes for the passenger one but I've not started to look at that yet
The gears are fine, the motor seems fine in both directions and the pot gives sensible readings

It sounds like the timing may be out. If you have diagnostics, you should be able to exercise it.

kermit_rr · Mar 29, 2020

Timing? Exercise?
I do have nanocom now! I can force calibration, which cycles cold hot on request, but can't 'force' a particular value ie 10% 20% etc it just stays on hot

Not got a Nanocom I have Faultmate, I can send the blend flap to any position, I would have thought that the Nanocom would be able to do the same.

It has ability, but the motor doesn't respond. Only moves when i request calibration, which i can do more than once without issue and no error code generated

kermit_rr · Mar 29, 2020

Can't force the other side either, but don't know what state that's in

Do you see different feedback values for cold & hot, can you see the value change as it does a calibration cycle?
I'm sure it's a feed back or timing problem.

wammers · Mar 29, 2020

If the pot is performing correctly and it has been assembled correctly it should be fine. Every time the ignition is switched on the blend motors should cycle then return to their selected position. Have you run calibration with Nanocom?

kermit_rr · Mar 29, 2020

Yes i see the value change but can't see if it goes all the way to zero or not as going thru the menus is too slow.
I did take the lid off the motor while still plugged in and turned the pot by hand, it went from 0-92 without any apparent dodgy readings in between

Yes I've done the calibration, which cycles from current position to cold, then hot and stops

Also measured the pot with my ohmmeter and that reads ok too, 0 to about 10.2k ohms
