All air vents blowing lukewarm air

ISTA should detect the issues and offer a test solution and remedial program…without stripping a very large amount of the dashboard you can’t get to the heat exchanger/ blowers..

If you pm me your email I can issue you an invite to newTIS…please don’t abuse that privilege..

I had to change the radiator today as it was leaking so took the opportunity to give the heater matrix a proper flush out with a hose. A couple of flushes both ways produced a few bits or grit/sandy deposits in the bucket but I wouldn’t say a lot. A refill and bleed because of the rad swap and she now seems to be breathing hot air again - result!!!

It’s always good to get the feedback when things go wrong and then a solution (pun) is found..
