Greetings BB'ers,

Always something with the 164 ('90 RHD Australia 3L 12valve model)

The first one is trivial - the wipers no longer "retract" back under the bonnet when not in use. Is there a switch or connector I can check? It sounds like a ground issue maybe?

Heater/aircon is more troublesome - for some reason the heater cannot be turned off. I know the airconditioner is running, because the compressor kicks in and out when I lower the temperature on the climate control. Is there are water valve which lets water in to the heater core from the engine coolant circuit? If so, perhaps the connection for this is dodgy?

Any pointers to fixing these bugs would be great, spring is getting closer and we're going to need the aircon!

No water valve as water runs through heater core at all times but there is a two-piece air temp door in blower motor housing that is controled by a wire cable attached to temp control stepper motor.

Check that lever in back of blower motor housing behind false firewall is not broken and cable moves it when stepper motor temp control is changed from low to high settings

read this thread about adding a heater core shut off valve http://www.alfabb.com/bb/forums/showthread.php?t=23143&highlight=murray H/C shut off valve: Murray #84707 Shut-Off Valve for 3/4" heater hose, found at local auto parts store, and make sure the heater door is opening and closing correctly, which is the only way that the factory provided for shutoff of heat.

Hi Benjamin,
I have the same problem with my current ('91) 164. The wipers seem to rest at the 'put away' position on every sweep, and when I turn the wipers off, they go to the same position.

On my '92, I remember watching the motor (cover removed) and noticing that for the final 'put away' sweep, the motor reversed direction.

Do you get the final sweep, i.e. if you turn the wipers onto intermittent, let them wipe once, and then turn them off, do they make another sweep? Or do they just turn off?

I'd be interested to know if the motor reverses, too. I was thinking about this and I reckon if the crank arm was attached to the motor at slightly the wrong angle, the reverse sweep wouldn't be any longer than the usual forward sweep.

I'm still not sure why the wiper is designed this way... on my '91, it means that with the wipers set near the bottom of the screen at rest, the driver's side wiper doesn't get anywhere close to the vertical edge of the windscreen - which is dangerous when approaching roundabouts. I almost wonder if it's worth trying to make a longer crank arm for the motor, to get a bit more stroke at the arms.

Cheers,
-Alex

Some more work done the daily drive 164 - I spent quite a bit of time on the window wiper mechanism and discovered that the components had pretty much jammed up with dirty grease and sheered off half of the 180 degree "ring" that makes up the retracting wiper component.

I think this is one of those cases a new part is preferable to one off a wreck, but there is no part number on this device and I couldn't find a reference to it on Eper.

So, can anyone help with a part number (AR or Bosch?) or perhaps a last resort a unit off a scrap 164? I don't need a whole motor assembly, just the retracting link which fits between the motor shalf and the wiper arm link.

Any help most appreciated!

Benjamin
