    Roadster 2.5 AC compressor replacement

    Sorry for the late response. The one that worked for me was Ford part no. AM64-19D623-AB. Get as high of serial number as you can as higher = Newer Replacement is a royal pain as you basically need to remove everything from the front area to get to it. Make sure you fill with Freon and...

    VehicleLogs file name year shows 2001 and 2002

    You’ll need the GPS firmware update. If you look at the link in this post it walks you thru what needs to be done. Tesla charges about 350 for the GPS update or you can do it yourself by borrowing one of the ones we have made available to the group. Takes about 10 mins to do the update if your...

    Roadster 2.5 AC compressor replacement

    Anyone know if there is a different brand besides the “ Tesla” AC compressor. I had heard there is a GM one that is a direct replacement. Peter or @MLAuto or anyone know of such a beast or know who makes the Tesla branded One and model number?

    Tons 'o' errors

    As a side note, you “Might” introduce the GPS rollover issue if you have old firmware in the GPS. The error shows a date that is about 19 or so years earlier. Since the power for the GPS is taken from that VMS connector, rebooting it might require you to flash your GPS with the correct...

    2.X battery capacity

    I got a REFURB battery in Nov of 2018. It wasn't a "NEW" battery and the range is nowhere NEAR a new 2.0 or 3.0 battery.... The CAC started at 159 which is a new 2.0 battery pack... but dropped to 135 within a few months.... You mileage may very... just my experience on battery replacement...

    Not what you want to see on a Saturday night...

    Interesting and Informative. I will add that my 2.5 (#1042) had an original battery with charge degradation due to sense lead failure on a brick. I think I got one of the LAST battery replacements available from Tesla last year ( Nov 2019). Just wanted to note my "supposed" newer model...

    Think I need a new PEM Fan... Anything else to check?

    Think I need a new PEM Fan... Anything else to check?

    You ALSO might want to check the TWO connectors on the underside next to the FAN. Just pull the diffuser rear underneath cover. 4 bolts and about 10 screws. Comes off easily. Mine were both fried causing 1144 errors On my 2.5 version. Replacing them with a better sized connectors...

    Putting into the service mode as shown here where its "popped" out about slightly. You can use a small slotted screwdriver in both sides to pop it out. You can see the tabs just above where my fingers are on the left and right sides. work one side, then the other until it pops up. I will...

    Think I need a new PEM Fan... Anything else to check?

    A couple of side notes from my lessons learned replacing the connector and a few pics of the connectors new. The cheap crimpers from Amazon didnt really do that great of a job crimping, even after several tries. It just wasnt a tight clean crimp. I opted for the less expensive MOLEX crimper...

    Think I need a new PEM Fan... Anything else to check?

    Yes you certainly need the connector replaced it will only get worse with time and with more arcing as the gap gets wider with the fan turning on and off. The service LIFE of these MOLEX MLX150 connectors is only about 20 cycles (which is the times connected and unconnected) on BOTH the...

    Think I need a new PEM Fan... Anything else to check?

    I don’t remember the 6 pin socket being pushed in but def pin 1 of RHC34 pem fan socket was. The 6 pin one goes to the ESS heater and would not be causing your issue. Its def the PEM fan socket and connector here are a few more pics of the PEM CIC board. it’s a pain in the ass to get too...

    Think I need a new PEM Fan... Anything else to check?

    I actually just went thru this with my car. I dont know if I would BRIDGE those two together as if one is powered and the other isnt, it might cause an issue with the PEM. I ended up for now replacing the connectors. As @PV-EV noted, you need to pull the whole pem to replace the connector as...

    PEM FAN Connector pin identification

    i actually did just that. Took a few hours to pull and open the pem. Get the CIC board out and replace the connector on the pem. Was a good learning experience. I can probably document it better if someone is looking to do it. Have lots of pics as I broke it down and put it back. Just...

    PEM FAN Connector pin identification

    The "Roadster Circuits - 2010 LHD PDF" I have shows different color wires, Mine shows BLACK wires but the rear harness and your note shows brown wires, which is exactly what color my harness has. Based on the connector damage it looks like pin #1 is in use... maybe some of #2 as well as it...

    PEM FAN Connector pin identification

    On the 1.5 there were TWO motors, One MOTOR FAN and one PEM FAN. On the 2.0/2.5 there is one motor driving both fans. So not sure which pins are actually in use. I know the fan is 12V based on the SPAL fan specs and based on the connector damage it looks like its using the MOTOR pins ( #1...

    PEM FAN Connector pin identification

    Any suggestion from testing it at the RHC34 connector after it’s removed from PEM? I have to rewire the connector anyway so was just going to feed 12v to pins 2 and 4 and see if fan blows.. Ohm test as well? Just looking for suggestions before I actually have to crawl under car and test from...

    PEM FAN Connector pin identification

    weird when I look at the schematics, the wire colors differ as well... I must have a different diagram then you do @MLAUTO . Looks Like Pins 1 and 3 go to some Motor Cooling fan and pins 2 and 4 go to PEM cooling fan. Colors are not what shows up under PEM. typical....

    PEM FAN Connector pin identification

    Anybody happen to have the pin-out labels for Rear Harness Connector 34 ( RHC34) as shown below. This is the PEM connector that attaches to the PEM FAN connector on the bottom of the PEM istelf. I have the pins but not what each line I used for. I'm guessing PIN 1 is 12v Positive and 2 is...

    Date on the Roadster is wrong - trashing log files

    Its Hit or Miss at the SC's on this. I had to EDUCATE the Houston NW SC about the GPS rollover issue, they kept wanting to replace other stuff, even the new replacement GPS unit sent from Tesla CA as a replacement had the older firmware. So based on the new unit being faulty, their response...

    I can attest to Carl's work as well. I'll caution you on "body shops" that have Little to NO experience with Roadsters, When Carl got my damaged car, obviously someone had tried to fix it improperly before I owned it. Looks like they used the wrong glue to fuse some of the parts together...

    New Roadster owner

    I concur... My 2.5 is like a Dyson Vacuum pulling up all kind of debris and road trash. LOTS of DUST and leaves in the PEM that needs to be cleaned out. My 1.5 never had that kind of issue. As also stated earlier, by taking off the PEM to clean, the FAN connector will become an issue as the...

    Today's Roadster Orphan

    Love the car and color.... however the R80 Battery pack charge screen at about 75% "ish" only shows 165 range.... seems LOW for that battery.... I extrapolate that out to about 220 range fully charged at best.. Still way low for a R80 pack with 4K miles on it. Wish someone can pull the CAC on...

    Sudden loss of range and what to do now

    I think the 156 CAC value is not valid and not a true CAC. I think it " POPS" to the high value as soon as the battery is switched, then learns what it actually is. Mine had a 157 or so after my battery replacement with a refurb. These are used sheets taken from other packs at Tesla and they...

    Updating 12V Battery

    Its a fairly easy process to jack up the wheel and replace the battery. Takes about an hour depending on what condition the fasteners are in and how hard they are to get off. A few of mine needed to be replaced with SS ones as the old ones were rusted in. Still was about an hour process...

    Caution - Annual Service - Car power-down - GPS issue

    Sounds like for some reason your VMS rebooted / reset which caused the GPS to power cycle. If you have one of the "faulty" GPS units, power cycling the VMS or an Annual can trigger the issue. Mine was an annual service that triggered If you VDS shows an older date in the 2000 range, mine at...
