Hi there everyone, Long time reader - first time poster.
My girlfriend got a Tipo digidash DGT for christmas, couple of probs to fix, mostly electrics in doors however i'm kinda stumped over the heater not working, the matrix is clear, there dosn't seem to be an airlock and both pipes going into the heater matrix get cozy warm, just no warm air ever comes out, the fan works fine so kinda chilly and demisting is an adventure at this time of year..
I got some parts from a scrap later model analogue dash (mk 2?) 1.4 recently and while there noticed that a vaccum pipe that seems to go from exhaust maifold to carb had a teepiece which had a pipe that seemed to dissapear into behind the dash through the firewall, I wondered if the heater controls have a vaccum assist to control the flaps and that could be our problem as the teepiece on ours dosn't have a pipe on it, I can feel a slight vac from it using a finger, I wonder if it should be blocked or if the pipe is missing. (perhaps this extra pipe is for analogue economy guages or is missing somthing on ours?) I note blocking this teepiece dosn't seem to effect running of the engine..
I have read forum posts suggesting controls can fail or a valve within the heater assembly...any way to test these as the hot cold knob clearly moves two sets of pushrods on the side of the heater box.
Any advice appreciated.
