Hi guy,s, this is my first post, I have got a 1996 VW sharan 2.8 GL with climate control that seems to control both front and back heater blowers (as there are no seperate controls in the roof lining for the rear one). Now here is the strange thing, the blowers only work in short blasts when the radiator cooling fan kicks in to cool the water in the radiator. I have changed the Blower Resistor pack (red hedgehog) I have changed the climate control header unit as the one was flash for a short while when first started up, now the new on is doing the same (proberbly no gas in A/C). I have even bought Relay 114, but cannot find where it goes as there is not an old one in the central fuse box, My central fuse box is only one level and not the multiple levels that was introduced late 1997. I also think that there may be a couple of relays missing but I cannot get my hands on a wiring diagram of my type of fuse box. Pleas can anyone help me. P.S Rear wiper not working, but the rear waher does work.
