Rear Wiper & Park Position?

Post by spegru » Mon Aug 19, 2019 10:44 am

Having used my SE6a in the rain a bit this weekend I now realise how useful the rear wiper is. However the park position for the rear wiper is a bit of a mystery to me.
The wiper has to park on the bodywork in order for the hatch to open, but does that mean in normal operation the wiper wipes back and forth over the bodywork as well?
Seems to me that the wipe angle should only include the glass area - but then how would it be possible for the park position be in a different place?.
Also, is the rear wiper really two speed?

Rear Wiper & Park Position?

There's a little slip linkage in the rear wiper gearbox which does a proverbial dance from a fixed sweep wheel:

Parked off screen.
Turn on wiper.
First upsweep only goes part way up the screen.
First downsweep doesn't go all the way back down - the linkage is now engaged in "running" mode.
Second upsweep goes all the to max sweep.
Second downsweep returns to remain on the glass.
Continual running now sweeps the full glass area (pretty much).
Turn wipers off, now it goes through the parking dance with partial sweeps to put the linkage into "parking mode" - it does part-sweeps, then should park off the screen.

I might have got that slightly wrong but it's a while since I've used a GTE rear wiper..

There is a useful stainless steel body protector accessory for the rear hatch. Not sure if gw sells it? It also seems to aid the blade returning to park as it's slipperier than painted fibreglass.

That's very interesting. That linked topic diagram reveals a very odd motor crank arm. Looks like this is not just a standard lucas motor. I might even take it out for a look inside...
It's not parking right now but I wonder if that's because If messed up the connection behind the rotary switch
But at least It's now obvious this is not a stupid design

Thanks for the info

Nigel (QRG) lists them on his website - £15 (+VAT etc, I assume).

Is "slipperier" a real word?

I removed my SS plate when the car was re-sprayed as under it the GRP had suffered badly. I now just let the wiper park on the glass and lift it clear to access the rear space - not a big deal but you do have to be careful that you don't let the arm "snap" back down and crack off a bit of paint from the opening.

The other point to be careful of, if you leave the wiper parking on the glass, is that when you've left the wiper up to access the load space, it would be all too easy to lean in to find something, and poke your eye out! :shock:

Indeed, only near-misses fortunately, but it does make you cringe a bit... :wink:
