Come on you two, sort this argument out! 😝
 
Last year I put vacuum on my Blue P38 AC system, but didn't get round to having it gassed. Re-checked to day & it still has full vacuum, so hopefully gonna get it done this week. Green P38 AC is nice & cold, so that one is getting used mostly.

While I was outside, I puts some exta R134 in wife's FL1, because although the AC was working it wasn't great. 80% of a can later, and the gauges are now showing 45 Low & 210 high. Cabin nicely cold & happy wife.
 
AC was regassed a couple of weeks ago, lovely..until today. Book came up, heat on full drivers side, passenger side cool, both set to low on the hvac. Cycling the ign didn't cure it so I had to carry on, 2 hrs round trip getting cooked.
Back home now so I'll get the nano on it. Bottom motor on the box rhs isn't it? I forget. Got a spare motor or two off @kermit_rr if needs be.

Yes it's the bottom one.
It's a long shot but try unplugging the power to the hvac to force a learn cycle. Failing that, flash the relevant motor terminals with a 9v battery (both ways) to give it a nudge

Nano says the pot is duff. I've tried forcing it with the nano but getting no % movements. I remember unplugging the hvac last year, I think, which fixed something that wouldn't work. iirc, all motors were working as they should but the book wouldn't go out. I really ought to be keeping a diary of what I fiddle with as I always think I'll remember but I don't.:rolleyes:.
 
Cycling the ign didn't work , then the blower wouldn't speed up then I remembered that I hadn't put 'back to ecu control' on the nano but then the blower speed started to respond without plugging the nano back in again. Might strip it all down tomorrow, too bloody hot inside the rangey.
 
Decided to brave the heat and strip it down. Question if I may...
I've got the clock cluster unplugged and out. Ign has been off for a couple of hours, is it safe to put the ign on to fiddle with the , now removed, blend motor? Or will the srs go off?

Clock cluster? Do you mean the dash binnacle rev counter/speedo etc?
The clock/radio/hvac have nothing to do with srs to my knowledge, only the binnacle with the srs warning light /message centre
