topradio Posted October 12, 2020 Report Share Posted October 12, 2020 When I took my 986 for MOT a few weeks ago I noticed that one of the two washer jets on each side didn't work, this didn't cause a problem with the test fortunately but I made a mental note to fix them. So, this weekend I took a look and as I know on some cars they are really difficult to unblock I decided to remove the whole unit. It turns out that the hole is quite big, perhaps 1 mm and I could clear them easily with a small needle. However I found something that I didn't know, they are heated. I'm not sure what the condition is that turns on the circuit, perhaps when the wipers are on or more likely when the heated window/mirrors are operational?

½cwt Posted October 12, 2020 Report Share Posted October 12, 2020 But what switches them on? Automatic on external temp, heated rear screen switch (remember early cars have a vinyl rear window with on elements) or heated mirrors, not standard?

So they are heated all summer also? Not when temp gets lower than 10C or similar? Perhaps they just need a low current? Link to comment Share on other sites More sharing options...
Danncus Posted October 14, 2020 Report Share Posted October 14, 2020 These don’t heat the water, just enough to melt any ice in the nozzle. Link to comment Share on other sites More sharing options...
