I have a 110 300 Tdi and had instaledl the standard (?) Euro AC in it. I wasn't present for the installation so need help withthe following ...
To get heat I need to pull down the regular cable to enable the heater blower but no flow goes through the two holes to the feet. I need to also turn on the AC blower and flow comes out the AC vents. Is this the normal setup for this system? I don't recall any of you Tdi guys ever mentioning your system working like mine.
I assumed the heat would work as before, through the two holes below but I actually prefer it this new way as I get more flow and better overall heat. The only glitch: I get very little, constant flow to the demisters but can live with that.
Also, I've always had the familiar problem of little flow from the far left AC vent (as in my '97 D90 NAS) but the other day I lost flow to the first and second vents from the left. I still get great flow from the other two on the right. Blocking those does not change flow from the two lefts - still no flow.
Can someone tell me how the ducting works on this system? A pic/diagram perhaps? I need to determine why no flow in the two left vents.
My '97 D90 NAS has the same looking AC system except that the switches are in the center and the overall length is shorter (better on the legs on the left). However, it does not produce any heat, just AC, through the forward vents. Heat still flows to the two holes below (as you all know).
It sounds like either system can be fitted either way? The other difference is in the AC switch: on the NAS turning on the AC blower always engages the AC, as the temp switch is always on. In the Euro setup the two switches are independent: turning on the AC blower produces non AC air/heat; turning the AC temp switch on produces AC air. Of course, if I had heat on before I need to turn off the stock heater blower with the cable.
The unlimate goal is to get rid of the entire stock setup - heater matrix, blower and cables. I hope to find a small unit with direct ducts to the vents all controlled by electric motors. Sort of like the typical setup in my Corolla: three rotary controls for air temp/blower speed/direction, all three mounted in the center console. Nice! I should also benefit from a more efficient matrix - assuming Toyota is smarter at this then LR!
I may look to retrofit the stock setup by adding electric motors to replace the cables - if such things are available. At the very least, I will route ducting to the actual vents and fit a fllapper to control direction. This will eliminate using the large, inefficient plenum and certainly get better flow.
