Rusted spindle due lack of lubrication - free it off and apply copious grease under the rubber boot - been there done that (my wiper seized up completely).

I may have posted this comment previously. A similar problem on a Honda Civic prompted me to buy a pattern replacement pump. However on removing the old pump from the tank base it turned out that the fine mesh strainer on the inlet was blocked with gunge. Existing pump was put back after cleaning the strainer and has continued to work fine.

For info only, I came across this site (charm dot li) on Facebook which provides free all makes workshop information. Take a peek and see what you think.

In order to replace a fan, I think the fan panel would have to be removed as an assembly after disconnecting various electrical connectors and the bolts holding the panel to the rear of the radiator / radiator /AC condenser pack. Someone who has actually done a fan swop or replaced the engine radiator (not me!) may know better.

This is the YouTube video I referred to above. Access to the control unit only requires removal of the battery cover, not the whole battery. Another RX400h video with power steering failure was diagnosed with a blown fuse located on the control unit.

This “relay switch” is located under the HV battery and according to a YouTube video I’ve seen, access to it means removal of the rear seats and battery. Hence Lexus labour cost of this work will be substantial.

My experience is similar, living near the Irish Sea coast, however I believe that road salt is a bigger cause of corrosion than wind borne sea salt. My last two MOT passes in January ‘23 and ‘24 both had advisories for rear subframe corrosion. When the weather is more amenable I plan to pressure wash the subframe and then spray it thoroughly with Lanoguard. I hope I won’t get chased by any sheepdogs!!. If you have smelled Lanoguard you will know what I mean. Lanoguard is obviously derived from the greasy by product of the wool scouring process.

Sorry my mistake - should have read further 🙄! D2S and D4S are NOT interchangeable as they operate at different voltages. The 3x price factor was for a higher output version of the D2S compared to the standard one.

This US(?) post on the Facebook RX group may be of interest. According to my RX400h owners manual D2S HID bulbs are used for the headlamp dipped beams. A quick search shows that D2S and D4S bulbs are interchangeable, with the same light output, but the environmentally friendly mercury free D4S typically costs 3x the cost of the D2S. https://www.facebook.com/groups/298564897176011/permalink/2016830915349392/? The other possibility of course is the dazzlingly bright LED option!!

I did this job on my 400h recently to replace a badly rusted rear disc + pads (partly caused by salty winds from living near the Irish Sea) and didn’t take any extra precautions. Removing one of the caliper slide pins was a problem due to some corrosion and the rubber grommet on the end becoming dislodged. The other frustrating part of the job is adjusting the handbrake shoe clearance by poking a screwdriver through the drum to turn a star wheel which you can only locate by feel.

I had a similar windscreen washer problem on my Honda Civic and after buying a replacement I removed the old pump via the wheel arch access method. The fine plastic mesh strainer on the pump inlet was totally blocked with gunge. After cleaning it and giving the tank a good flush out the old pump worked fine.

Hi Dave, I too experience the corrosive effects of wind driven Irish Sea salt living in West Cumbria. When I repaired my seized rear wiper I took the opportunity to clean up this nut, while it was off, and gave it a couple of coats of black paint.

I had my windscreen well starred and cracked today by an unknown missile so it will be a full replacement job. Has anyone got any experiences of RX screen replacement by Autoglass?

I had the same problem a few years back and managed to clean up and free off the seized rusty shaft followed by liberal application of oil and grease. Motor was fine. No problems since.

Brake actuator pump motor faulty? Normally this motor runs intermittently to maintain the brake accumulator pressure and is barely noticeable when operating.
