I already have this off and have checked the fuses I found. 2 alarm (one was blown) and four others which are all good. I haven't yet checked the switch though.Sorry, I did say assuming its a 91 MY, I checked my 93 LSE this morning and as you say its C5, but thats for the fronts, have you checked the obvious, the switches aren't very good and get worse with age, have you tried checking the continuity of the switch, it'll involve taking the underside of the dash off and steering cowling off to get to the white plug thats cable tied to the steering column and it gives you more to work with.
You remember correct. I also think the two are related but finding out where the problem is is the problem if you follow me.Did you say in another post that you're interior lights aren't working either as there's a feed for the Timer Unit (Pink/Green wire) from the interior light circuit, the purpose of the timer is to wipe the rear window 3 times after the wash wipe has been pressed, if so, seems a bit of a coincidence .
I will try and trace the wires from the switch but as I said above the fuses I have found are all good so far. I am fairly certain it is a fuse as there is no relay noise when the swith is operated (BTW it was working when I picked it up . Changing the back hatch seems to have caused the problem)There's 2 fuses involved in the Rear Wash/Wipe, E3 seems to supply the feed to the switch, I don't know whether this is an in-line fuse or not, but it should be a White wire with a Light Green tracer from the white connector that the wiper switch plugs into, the other fuse is B5, which powers the Park Switch in the wiper motor, but I cant see that having anything to do with it.
I have owned and still love Alfa's (is this the definition of masochism?) their electrics were never this much fun. :lol:And I thought it was only Italians cars that had bad auto electrics.
