2006 RX330 Liftgate Lock Actuator Repair

Recommended Posts

2006 RX330 210,000 km runs fine. NOT powered open or close kind, very basic liftgate strut style with a open switch on it.

Failing Lock actuator symptom: Liftgate locker stuck close sometimes after press release button[switch], very weak or slow click from lock actuator motor, most of time the locking system may work after the first press,but second and third press within short time almost impossible get locker release. same pattern will happen after lock and unlock the car couple minutes later.

I guess the thermistor [kind of motor overheat protection] inside the motor is shot, so a motor replacement worth a try as it is dirty cheaper than a actuator assembly.

After replace the motor only, now the liftgate lock release works very well with strong motor running sound even continue press unlock switch.

Start from both side and pull hard.

      Hello! My name is Jake and I have an 04 RX330 with 230,000 miles on it. Not certain on the history of it but I have gotten it with no heat and an overheating problem(EDIT: previous owners said it has overheated on them). I immediately knocked out the easy stuff, checked coolant levels, verified fans were working. So I end up doing serious work that it needed: waterpump, timing belt, power steering pump, upper/lower intake gaskets, thermostat(THM 117-$11.32 at napa), valve cover gaskets, spark plugs. I end up finding smoke swirling out of a crack in the radiator while the car was idling for an hour during a fuel injector decarbonizing process. I end up replacing the radiator as well as the fan motors with the relay because the fans wouldn't turn on. I ended up using a power probe straight to the old fan motors and only fan #2 worked. I end up putting it all together-bled all of the air out of the cooling system with an airlift evacuation tool-and this thing is still overheating! Today I pulled it in and put the scantool on it-temp reads 244 degrees, so it's up there. I take a laser thermometer gun and the passenger-side (or upper hose) of the radiator read 183 degrees give or take and the part of the intake that the sensor screws into was around the same. So I thought it's only a $20 sensor, and replaced it-also considering it had a previous P0117 code(engine coolant temperature circuit low input). I know when the DTC is aiming at the input part of a circuit, it's talking about something with the sensor. I thought this would do it, BUT the car still overheats via gauge. Good news was I had heat, so I'd blast it when it starts climbing up and it'd slowly go down. I'm really stumped now, because I know the heater core acts as a mini radiator, but it doesn't make sense that the heatercore cools the engine down but not the fans and radiator being fully functional. The upper heater hose is piping hot with pressure but the lower hose is room temperature with pressure, I verified by squeezing the hoses. Is the thermostat defective? I installed it with the wobbler pin positioned at the top via installation instructions. I feel like I might run a compression test tomorrow to check the head gaskets, but I feel like I'm missing another sensor or something-I'm a freshman in college so anyone with experience I'd greatly appreciate it!

      My guess would be either the first gen rx300 or the most recent gen rx350 because they have the most ground clearance. Not sure how they all compare with locking diffs, gearing, wheel articulation, low end torque, etc since I only own the first gen. 
      Second question: is the RX a lot worse off road than the LX and GX or are they close?

      I have a 2004 RX330 which has a 6 CD changer and a cassette player.  Has anyone had any success installing an adapter such as this one to allow direct mp3 input?   I have a FM radio  transmitter, but the reception from my phone from the headphone jack through the transmitter is spotty and has static.  I don't want to use bluetooth.  I'm having the dash replaced by the dealer so I thought this would be a good time to do this. Thanks for any guidance/suggestions. Bob  http://pac-audio.com/productDetails.aspx?ProductId=1082&CategoryID=45

      The topic name is self explanatory, Passengers side HID light is dead, replaced the bulb (D2S) with a new one, still dead, checked the old bulb in the drivers side light fixture, works fine, so the problem is not with the bulb. Checked the connections, look clean and good. What else could it be. Thank you.
      P.S. Dont want to go to my mechanic if it is something I can fix on my own.
