wombling 2 Posted January 18, 2014 Share Posted January 18, 2014 The rear screen wiper on my car continues to constantly work on "intermittant", even although I have selected "off" on the control stalk.The other wiper/washer functions appear to work ok, but the wiper will only stop completely when the ignition is turned off !Would this be a problem with the stalk-switch, or with the wiper motor?Has anyone else experienced this weird trouble?Any advice would be welcome.

t-spiritpete 119 Posted January 18, 2014 Share Posted January 18, 2014 Hello Derek,This problem is usually due to water getting into the wiper motor which needs to be removed and dried out, reassemble with plenty of grease on the shaft that connects to the wiper arm, this may keep the water out if the seals are worn or perished. This is a cheap fix if you can do the job yourself and well worth a try.Pete. 3 Quote Link to post Share on other sites

wombling 2 Posted January 21, 2014 Author Share Posted January 21, 2014 Hi guysThanks for your repliesI had to wait for a dry day to work on the car, as I don't have an under-cover area. Am glad to report, however, that after some hours of glorious British Sunshine, the fault appears to have cured itself! Obviously something must have dried out since the deluges of rain we've had here recently.If the problem repeats itself, and I have to access the wiper motor, could either of you point me in the right direction to get instructions on how to remove the interior trim panel from the hatch-back lid? Being a rank amateur in these matters, I cannot see any obvious way of removing this!Many thanks in advance.Derek Quote Link to post Share on other sites

Konrad C 958 Posted January 25, 2014 Share Posted January 25, 2014 After years of the rear wiper intermittent mode problem, I tackled the problem.The following is for the Mk1.At the wiper arm, remove the cover and undo the nut but, don't remove yet. Using a fair large flat blade screwdriver or a special puller, lever or pull the viper arm off the spindle, then remove the nut and wiper arm.Only 1 screw in the inside door handle needs to be removed, then the inner trim. Then undo 3 bolts. Disconnect the plug and pull the motor from the door.I also remove the rubber grommet, noting the small arrow embossed, which points towards the front. Following Pete's suggestion, I greased the spindle inside the motor, reshaped the cover slightly and re-greased that, and re-soldered 2 of 4 contact joints which looked dry.Using silicon sealant on the top of the spindle, around the hole where the grommet sits, and along the spindle which goes through the grommet. Add thick polythene material and the motor hopefully should be dry.The motor seems to be working fine for now. 1 Quote Link to post Share on other sites
adman 0 Posted March 5, 2015 Share Posted March 5, 2015 Hi, Thanks for the pics - very helpful. I have the same problem. I'm pretty thin on tools, but thinking of getting a set or something. Could you tell me what tools you need to do all of this? Ta Quote Link to post Share on other sites

Could you tell me what tools you need to do all of this? TaSocket set and screw drivers. I got a trim removal tool from Machine Mart. You may need a wiper removal tool.

Onslow2001 0 Posted February 22 Share Posted February 22 Hi After the recent heavy rain and snow I now have the same problem with the rear wiper not turning off on my 2001 Avensis mk1, I removed the wiper motor and disconnected the electrical connector then but the wiper motor back on as a quick fix any idea where I can obtain a new grommet from. Any help in finding a new grommet would be great. Quote Link to post Share on other sites

Any help in finding a new grommet would be great. The obvious place will be the dealers. Here is the part number - 85143-05030 http://www.japan-parts.eu/toyota/eu/1998/avensis/at221r-almekw/3_273540_026_/electrical/8502_rear-wiper#85143R You could all try Ebay or similar to compare prices. I would not try second-hand, unless the seller can vouch the grommet was a new replacement! Also try silicon sealant and silicon grease around the spindle. Quote Link to post Share on other sites
Onslow2001 0 Posted February 23 Share Posted February 23 Thanks for the prompt reply we have a main dealer in Newcastle will give them a try, looked on Ebay but can't see anything available. Avensis4d786 mentioned he got one from Mr T for £5 but that was back in 2014. If not available I'll go down the silicon sealant and grease route. Thanks again Quote Link to post Share on other sites
