    Notice you have a conversion, I have a 2003 LS3 996 C4S with a 495 HP.  I have 20,000 miles on the new engine, I'm doing another car project and have my Porsche for sale.  If you know of any potential buyers please send them my way, and yes...  The A/C works as well as the cruise control.

     

    There isn't another conversion that is as good as this one, I've invested a 1.5 years in the conversion and 100K, asking $69,750

    Very noticable vibration just started and I want to say it is one or both of the driveshafts. Approaching 140k miles and I belive they are original. Anyway to check and verify that the cv joints are indeed nearing their end? What am I looking at for cost of repair? Special tools needed for DIY?
  3. pdogfly
    Well I did get another AC relay...used albiet, but just for testing I guess. Hopefully will have the system serviced back up tomorrow and be able to check the new relay and see if it really was that simple. We'll see... If it doesn't work I'm going to take it to the dealer or to a Porsche specialist in the area to see if they can hook up a scan tool with the ability to test the circuit to see if the DME or AC control unit is faulty I guess.

    With the relay removed even, the pin (85) going to the DME is showing 5~6v, why would there be positive voltage if this is the wire that is supplied a ground via the DME when commanded "ON"? Shouldn't it be an open circuit with the A/C off, neither grounded or any positive voltage supplied?
  5. pdogfly
    Any idea why I'm getting battery voltage with Key-On at Pin 85 on the Relay, if the DME provides a ground to this Pin, shouldn't it be open w/ no voltage?
  6. pdogfly
    x59/2? Is the TV signal the coaxial cable? :D
  7. pdogfly
    Cool, I'll check that stuff out tomorrow. I'm not real good at following the wiring diagram when it goes from one harness to another. when the wires end in those boxes with the letter and numbers that you chase to another diagram. Can you tell me which pins on the engine harness cannon plugs you're referring to above? Where are you from man? I'd invite you over and pay for all the beer if you were in Lauderdale, haha, really appreciate the guidance, helping out a ton!
  8. pdogfly
    Yes 85 & 62 are untouched, and Pin 85 is showing 5~6v with the relay removed, and with the relay installed it shows 12+v. Do you know what the voltage range is on the throttle position sensor...maybe I can tie it into the GM sensor which is .5~.6v @ idle and 4.5v+ @ WOT. I do have a stock Porsche temp sensor, it has 4 pins on the sensor but I'm not sure how it should be wired. At this point I'm going to try to find an engine harness so I can tie in as much as I can so both computers "think" they are operating normally, haha...

    Yes I have a wiring diagram of the car. The 2 pins are connected correctly, they were never touched throughout the engine swap process. Only the engine harness was removed (2 cannon plugs in engine bay). Does the DME use things like throttle position etc... as a funtion of controling the AC in this case?
  10. pdogfly
    Ok, I thought Pin 69 was part of what got removed from the engine harness. the factory wiring inside the car has not been altered as far as the A/C system is concerned. Only the engine bay harness has been removed from the car. The enigne RPM signal now comes from the GM computer that ties into the DME Pin 78. I'm thinking the DME is looking for either a running engine or some sort of signal that it isn't getting or isn't there for the system to be properly activated. So Pin 69 @ the DME and Pin D6 @ the AC unit are factory.
  11. pdogfly
    Faaantastic. Suggestions on where to go from here? Could it be the A/C head unit? Find someone with a durametric? Your input is much appreciated...just wish I could figure this gremlin out. -pg
  12. pdogfly
    Ok...I disconnected the plug from the compressor and Pin 87 is no longer grounded. The GM compressor has 2 wires coming off of it, in theroy one (+) and one (-). With either wire connected to ground, the opposite wire will ohm to ground as well. I had it set up with the Pin 87 wire running to the (+) wire on the compressor, and the "ground" wire on the compressor....grounded. Essentially grounding Pin 87. I'm not sure if the OEM Porsche Compressor is a single wire or 2 wire compressor. But this may shed some light on the situation....
  13. pdogfly
    With the relay removed Pin 85 shows 5~6v, everything else is the same... Not sure why Pin 87 and 87a are both ohming out to ground? :cursing:
  14. pdogfly
    Ok, here's what is going on @ the A/C Relay currently... Pin 85 (pinkish wire with green stripe) & 86 (red wire with blue stripe) are both showing 12+v with engine running, AC button on or off. Pin 87 (green wire with yellow stripe) is ohm'ing out to GND with button on or off. Pin 87a (brown wire) is also ohm'ing out to ground. Pin 30 (purple wire with yellow stripe) is showing 12+v with engine running, AC button on or off.

    Alllllrighty then. Just serviced the system with 2lbs of freon (3 12oz. cans). With the compressor jumpered and engine at idle, cooling fans on high, it is blowing cold. :thumbup: Used vac pump to suck down for 15m before servicing. Checked the pressure switch and with key on and 12 volts is present at both pins #1 and #4 so that tells me that the switch is ok. Still no joy with the AC button on the control head unit on the dash. I'm going to check the relay readings again and wil post back...
