I've been assembling all the parts to re-install heat in my teener, and now I'm down to checking out all the wiring. But I'm not getting any power to the rear heater fan (in engine bay).
I've cleaned up the connectors and wiring from the heater switch behind the shifter (ground side of the circuit). It comes out at pin #9 on the forward 14-pin connector on the relay board. Power should be going to pin #11 of the same connector, but Im gettin zip. This #11 connects to pin #10 of the lower-right 12-pin connector on the relay board - which bridges to pin #11 - then over to #87 of the relay. I'm getting power at #30 on the relay - but don't have a way to check where its going from there. The relay is new, and I've swapped with others - but keep ending up with no power. Any ideas - what I might be missing? TIA, |

NEWS FLASH !!!! NEWS FLASH !!!!
I did some further investigating with the heater lever and I have my final report. The lever portion is fully isolated from the plastic arm AND from the mounting bracket that bolts it to the floor. The grounding connection is applied to the lever via the bead on the plastic arm. From there the arm is grounded via the .... are you ready for this? ... via the METAL CABLES that connects to the heater boxes. DUHHHH! (IMG:style_emoticons/default/huh.gif) This is one place where I think Porsche really fell down on the design side. Unless someone can come to Porsches defense - I just don't get this one! Anyway - its one for the books - scrap books that is! Enjoy! |
