I turned the AC on today, there was a difference at first between driver and passenger air vents temperatures. But that was before the compressor started working properly (I know it's working good after cycling on/off when the passenger's vents are cold). So I'm not sure if the driver's vents plastic was "hotter" and needed a while to cool or something else was controlling the ait temp mixture? I don't know. I first used the car yesterday at 8:30 p.m., outside temperature was 31C. Anyway...
I opened the actuator and quickly noticed that the first gear in contact with the motor's worm gear, would move up and out of alignment with that worm gear and they disengage, when the motor was spinning counter-clockwise only. I was expecting some teeth or any gear damage, but nope, nothing. I took a video of the gear moving out:
I have three actuators from a salvage yard that I got when I first started hearing clicking noises a few years ago, I knew this day would come. So I started comparing, I switched gears even the worm gears, I switched motors and housings. In the end, I came to the conclusion that the shaft of that gear became too narrow. The same gear in other housing has a waaay tighter fit. So, the first solution that came in my mind was to push it down with a shim. So I put a washer over the gear and shaft so it would push down on the gear after the housing was assembled.
The motor was fixed using thick double side pads, I needed a screw driver to pry it out. So that must be significant? I the glued the motor with super glue, it should stay put.
I reassembled the actuator and took the following video:
It kept going without any issue, so hopefully this shim/washer fixes that problem. It may take me a while to reinstall the actuator back into the car, but I will update this thread when that happens.
Does any know how to power the actuator/motor through the pins (the pins the oem wires connect to)
I couldn't power any of the actuators with any combination of pins and +ve/-ve wires (this was all done with a 9v battery). I had to supply power direclty to the motor, and use on of two pins. But I couldn't supply any two pins with power directly from the battery and have the thing work. If I can get an answer to this I would be grateful.
