The driver's side (UK RHD) door mirror has just stopped fully opening on my 6 year old GX4h PHEV. I initially noticed that it wasn't in the fully open position and thought that somebody had knocked it half closed walking past, but then I realised that it wasn't opening fully in the first place. I've always had the mirrors set to open and close when the key fob/plipper is pressed when unlocking and locking the doors.
I opened it fully with my hand, and then when I pressed the fob to lock the doors the mirror mechanism made a 'thunk' noise and closed normally. But when I unlocked again the mirror only opens slightly less than half way. For now I've switched the auto open/close mirror function off within the MMCS so the mirrors stay in the open position. The passenger side mirror still operates as normal.
Anyone else experienced this problem? If so what's the fix and how difficult/expensive might it be?
