Dan, If none of the Homelink suggestions work, it may well be that your garage door system just isn't compatible with Homelink. Years ago I recall having a similar problem with an older garage door system and our Nissan at the time.

Dan, Having a 2008 suggests that you have a used car .. that may have its Homelink buttons already programmed to another garage door system. Watch this YouTube video to see if its procedures will solve your issue: https://homelink.com/lexus

Rafig609, Since the original factory tire size was 215/55/17 .... and you already have 235/45/18's installed, the only way to tell would be to mount a 245/45/18 and see if it conflicts with the shock tower and the inner fender well.

DaveES3502007, GoodLuck!

Lexuses350, This is just an educated guess, but I don't believe in coincidences. You pulled the fan relay and reinserted it ... and then your HVAC issues popped up? I'd go back into the fuse box (with the ignition off of course) and pull the HVAC relay and any associated fuses and check them out. Its possible that you have the same issue as with the fans, or they were next door and you displaced its relay? Note that many on board relays are exactly the same (number/color) and you can swap them out back and forth in the fuse box to determine which one is bad or good. Good Luck!

Kellz247, Check the exhaust system for leaks, use a catalytic converter cleaner to remove deposits, fix or replace a possibly damaged oxygen sensor, or replace the catalytic converter, are all possible fixes that any good independent mechanic can diagnose and correct, usually a lot cheaper than your Lexus dealership.

armcomdes, Get the car in the air and then take a dead blow hammer or heavy rubber mallet and start banging around on the entire rear suspension, one part at a time. Check the sway bar end links because they are famous for clunking noises. Grab each rear wheel and shake it up and down, back and forth. Check the rear struts for loose top mounts. Get into the trunk and check out everything not tied down, spare, tools, jack, etc.

Barbara H, I agree with paying to get another diagnosis, as hopefully you might get an explanation as to why the trunk release and fan speeds are affected with your nav screen issues. That said, a recent 2 part YouTube video on a Subaru water leak caused a TPMS failure (module is under the driver's seat in a subie and shorted out due to water flooding) that also caused the radio to malfunction, the speedometer not to work, and a complete communications failure of the diagnostics system for the car. Once the car was dried out and the TPMS module replaced, the radio, speedo and OBDII communications all started to work again. What I'm getting at is that many of your car's systems' issues can sometimes be caused by just one part failure. Maybe they are all related? Your best bet after the 2nd diagnosis is a refurbished unit if it backs up your first diagnosis. Its the cheapest route for you on a 9 year old car. (And no, you can't have the one from my wife's car.) Good Luck!

Jacobi, Don't know what you mean by "gulf specs", and what steering wheel button you're referring to as the Bluetooth button? What I can tell you is that if your car does not have the button for the feature you want, just changing the steering wheel to one that does will not give you that feature. There will be wiring harnesses through the steering column and dash board, and modules that will be required, as well as a change over to a different head unit (radio/navigation) even. It'll be pretty involved and costly unless you can find a wreck that has the features you're after. I suspect that you are referring to a hands free phone feature? If so do an Amazon or eBay search for "Parrot Hands Free" or similar device.

armcomdes, Find a good independent mechanic to solve your issue. Obviously your dealership isn't solving the problem, and an independent mechanic will do the job cheaper. You obviously have a leak in the system which a service tech must find first, repair, and then recharge the system. Be prepared for spending some bucks as some of the parts in the AC system can add up quickly if the problem isn't a simple seal. Good Luck!

Natan, These similar stains show up on all cars below the door handles as well, and from all outside attachments on all makes of RV's. Get to your local dollar store and buy some "L A's Totally Awesome" cleaner, the yellow container. It is dirt cheap to buy, and it simply can't be beat for removing these kinds of stains in a heart beat. Google search the name and check out the many YouTube videos for it.

Michel C, First off, it doesn't sound serious. Sounds like a loose accessory belt (steering/AC belt/etc.) Pull the plastic covers off of the engine, and when its cold at start up, look around in the engine bay and see if you can spot where the noise is coming from. It might be the AC clutch needing some lubrication or a bearing starting to go. If you can't tell yourself, with the panels off, take it to a good independent mechanic to find the source and suggest a fix. The center cover just pulls straight up, and all of the other panels are held on by push pins. Push down the center of each pin, then lift the entire plug assembly up and out to remove them. When reinstalling the panels, pull up on each pin center, until it sits above the outer ring by 3/16 th's of an inch or so, then place the plug into its panel hole, and push the center of the plug down , only until its flush with the plug's outer ring. Take pictures of which panels overlap each other, otherwise you'll get them down in place and find one or two panels you can't get back in place without dissasembling part of what you've already installed. (Ask me how I know?)

boystoys, Look carefully at the pictures on the listings (eBay) for the entire lid assembly and you'll see that there are several showing the lock button (about $150) and several without the button (about $30). The expensive ones are for the complete lid, button, skin and all. The cheaper ones are for the leather replacement skin only. If the complete assembly is what you need, but the listing is in the wrong colour, buy it and swap your skin on the one you buy. The lid assembly comes apart to change the leather skin. Its not rocket science.

lanalexus, First off, always give the mileage of the car because it often points us in a certain direction for a diagnosis. For an exhaust to get hot enough to glow means the engine was asked to work very hard (racing), or you have an exhaust restriction (plugged catalytic converter), or similar. You really need to get the car to somewhere and have a proper DTC code reading done. With the runs you are expecting to do shortly, it would be very unwise to neglect the heads up you car is giving you with its symptoms and engine light.

dionj34, You are still too vague. Get the hood open, have someone rev the car up several times while you stand in front of the car and determine where the sound appears to originate. Better yet, record a sound clip or video on your phone and post it here.
