Has there been any updates to this thread?

So still no luck getting this sorted - I tried reverse flushing heater core the other week, unfortunately made no difference though...

I know that this problem 9/10 times is due to blocked heater core (which I think my problem is also) but, I did plug my IID tool in and checked live values to see what both left and right blend motors were doing and I did get back a strange result (see pics below - 1st pic is with both temps set to max cold, 2nd is with bot temps set to HI [max hot]) - left (passenger side) doesn't appear to be behaving as expected? I managed to remove the left blend motor (which was a painful exercise in its self!) and was able to manually open and close blend flap, still had the same issue with no hot getting through on left so am guessing that it's still a heater core issue and the IID tool reading is just an anomaly?? ...or there could be an issue with blend door flap (probably will need to get hold of inspection / bore camera to check this)??

Wondering, does anyone else have a GAP IID tool handy that could check what yours is showing for left and right temperature blend motors?

Typically, I've left it till the last minute and now it's still not fixed and the cold is rolling in!!
