I wanted to thank you again for you...Good Day Dave,<br />I wanted to thank you again for your guidelines. Successfully repaired the headlights of my 944 S2 last weekend - very happy with that.<br />First, I have verified that the light switch and cabling works fine. <br />I have then disassembled the headlight motor and cleaned the rotary disc. The disc has shown only limited signs of wear, but some visible traces of particles smeared between the cut-out sections. I believe that these particles were conductive and have affected proper operation of the headlights; i.e. improper upper end position, then unintentional retraction, improper lower end position, unwanted pop-up and so forth --> "headlights tango". <br />I have assembled the unit after some careful sanding of the contacts with 600 emery paper and careful alignment, followed by a lubrication with Teslanol contact spray. Cleaned and re-lubricated the linkage/levers, too. <br />The rubber boot is still available from PORSCHE (Part No. 477 971 923 as you wrote) for 17€ in Germany as of Oct 2018, and I will also replace the relay (a standard relay). <br />I have seen only one single round of headlights tango since the overhaul. This was at the very first time when activated and the headlights work fine since then. The unit may need several cycles as the cleaned contacts need to form good electrical contact. <br />Notes to all PORSCHE fans with similar issues: <br />1) You can easily remove the MOLEX connector pins using common pin removal tools as used by PC modding hobbyists - but avoid the Phobya brand tool, as it is known to break. <br />2) You can save some time when you start with disconnecting the MOLEX connector and testing this according to PART A of Dave's tutorial. Leave the MOLEX disconnected, which saves you the time for pulling any fuses or for disconnecting the car battery. I strongly recommend you to work on the mechanism with the circuit non-energized - as the linkage can easily cut off a human finger! <br /><br />Thanks again, Dave - and please keep on creating these very useful tutorials. Let's keep these wonderful Transaxle-PORSCHEs rockin' and rollin'!<br /><br />Cheers,<br />M.

Since you've replaced the switch (I assume with a brand new one) I'd then test that you are at least getting on and off power out of the molex connector before you even connect it to the motor. If the you are getting on/off power then the problem must lie with the relay (which you say are good), the motor itself (clean the com like I did in my my tutorial) or the wheel and brush mechanism (make sure there's no corrosion on the wheel and that the brushes are actually making contact with it). Don't have the motor joined to the lifting mechanism at any time as you are only adding another culprit into the mix. Only once the motor spins should you connect it to the lifting mechanism.Davehttps://www.blogger.com/profile/02453087378158817318noreply@blogger.com
