Many thanks to everyone for their responses, very much appreciated. Normski2 - very useful guide, the pictures are really clear and with detailed explanations. ColinBarber - I tried listening to the rotor. I can only hear the rotor trying to work in the directions that the mirror glass will still tilt in. The problem direction produces no noise. From reading the guide that Normski2 provided and also looking at other Lexus forums / reading other posts on here, I tend to agree with you. It seems the problem is most likely either: 1 - one of the two rotors has failed and needs replacing; 2 - part of the rotor has corroded and needs a scrub (this seemed to be a fairly common reason for the issue?) I'll open up the mirror in the next few weeks and see where we get to. If it helps others in future who have the same problem, I believe the part number for 4th generation Lexus GS wing mirror glass tilting rotors is FC140RF7Z675. That is based on several searches on ebay and aliexpress. Relevant text from an aliexpress item listed for sale as I presume it's against community guidelines to post links: For Lexus GS 2012-2019 FC140RF7Z675 Genuine Wing Mirror Left Right Adjustment Motor Assembly I'll take pictures of the job when I get time to do it and post them here. Thanks RM

Hi Steve2006, Thanks for your input. I can move the problem mirror left and right, BUT NOT up and down. The other side mirror has full mobility (tilt glass up, down, left, right). Let me know if any of the above isn't clear 🙂 Thanks!! Best RM

Hello, You've probably made your decision already, however for the benefit for others who may look at the thread in future: I put "Michelin Primacy 4" tyres on my GS250 after researching potential tyres that would give a good balance of quality; noise; wet performance (East London! 🙂 ); and all seasons grip. I drive at the speed limit, accelerate to a medium degree in getting to the speed limit, but don't go over that. The tyres have held up great (perhaps unsurprising given I don't rag the car!), but they seem good. I'm sure there are better tyres if you want to drive fast, but they've been a good set of tyres for the money for me. Best RM

Hello! Hope everyone's keeping well? I'm a long term lurker on this forum, but I'm a DIY-er and would like to give back in the next week or two by posting some pictures of doing DIY oil and brake changes for others, given how much I've learned from this forum without interacting at all so far! My query is if anyone has any experience around fixing the following situation: Problem: When I put my GS250 into reverse it normally would tilt both wing (side) mirrors down to the pre-set levels. But, all of a sudden ONLY ONE of the two side mirrors (driver's side mirror is the one that stopped working in case that matters) will actually have its glass tilt down to the pre-set level when I put it into reverse. One reason I mention that only one mirror has a problem is to pre-empt the suggested solution from peers that perhaps its just that I haven't pushed either the left or right buttons on the driver's armrest (if no LEDs are on then it won't tilt for EITHER wing mirror I understand). I'd be keen to try and fix the problem myself (IF I can be pretty sure on what the actual problem is, so it's a one time fix!!!), but if I can't then I guess I may have to stomach a £500 wing mirror fix on a car worth £14000 which seems kinda disproportionate 🙂 hence my query to all of you fine gentlemen and gentlewomen! If anyone has any experience with this general situation, or any ideas I'd be all ears! All the best, and hope everyone's doing well ahead of Christmas 🙂 Many thanks RM
