Hi all.
I'm coming back to you guys ith my AirCon prob, as I've done the vac pipe test and here what are the results:
1. theres no water comin from the HBV vac pipe hole - which is a good sign
2. there was some heat comin on, but only if I keep the engine on the high revs
3. Entwood suggests, that this could be "a reverse flush of the heater matrix", but first I'd need to check if the rest of the HBV pipes are warm or cold. The unfortunate is, that the HBV location is slightly different (less visible and accessable) than shown on the guide.
any other ideas please

??
