Heater 1998 GT3
Discussion
i noticed at the weekend that whilst the fan works fan, the direction only seems to push air to the side and face vents. I had a couple of the trunking hoses off for access when i replaced the Wiper mechanism, but seeing as the 'feet' hose wasnt touched i dont understand why there is now no warm air. Effectively all i have is windscreen only. Any one else had this ? i am pretty sure the hoses went back where they were, in fact i dont think due to there size you can get it wrong (but not 100%) sure, and of course i have also assumed they were on correctly in the first place. But has anyone got a drawing or knowledge of where the trunking hoses should be ?
well the diagnosis was correct ! a vacuum pipe was of on the passenger side, so warm air into the cabin once more. need to check further though as it doesn't seem to matter where i turn the direction indicator, feet, face or screen as to what volume of air comes out, so maybe another pipe is off somewhere else, but for the moment i can at least clear the screen.
I had the same problem years back, the direction knob didn't change the airflow which always went to the screen. Turned out to be a little electric stepper motor burned out. It only had 2 positions, but had a drastic efect on the output. Very fiddly to replace and I think the Lotus part is obsolete, though the manufacturer was Diavia if you needed to look elsewhere.
