No, but it does speed up as you go faster. Actually what it does is just go slower when you are coming to a stop. All the intermittent settings do. It shouldn't wipe continuously unless you set it to one of those speeds.

When you set it to "on", it should set the wipers resting position about 6-7 inches up so you can pull them off the windshield when you park in snow, and it make de-icing easier. Set to off, they should rest low enough that you cannot raise them without hitting the hood. Mine a re a little wobbly and don't rest correctly. It's an age thing.

That would because of the voltage generated by the alternator decreases at lower speed, depending on the electrical load.

Head lights on etc

Re: Motor Week '91 SVX Road Test Video

the only vehicle speed sensing the wipers do is when the intermittent wiper is on the full setting... The wipers will not stop during driving just like they would on the slow setting. BUT once you come to a stop, the wipers run an intermittent cycle. Once you begin moving again, they return to a constant pace

Are you sure? But is that a side effect or intentional design? My money is on it being intentional. My wiper speed doesn't increase with rpms when stopped.

Is the way the alternator thingie works... It is more noticeable when headlights are on bright climate control fan is running full blast. I always drive with all this going on and when stoped at a light sometimes will just switch the lights to lo beam and see a pickup in wiper speed.

I think it is a current thing. faster alternator RPM... more current through the circuit...slower alternator turning causes less current.

Re: Motor Week '91 SVX Road Test Video

In my RHD 95 Aust model, the intermittent speed increases with speed. It is an intentional thing I think, not related to the alt output, unless the battery is low.

Re: Motor Week '91 SVX Road Test Video

Mine seems to vary with the difference in how wet or dry the windshield is, but not even sure about that. I thought that was a load current thing also.

I always have said these cars are interesting animals!

The wipers are designed to vary their speed with the vehicles speed. They started this in the XT6 (maybe XT)

If that is the case, the switch, or something else in the circuit isn't working.

It is supposed to change where the wipers "park" either down out of sight or up on the windshield where you can see them.

Thanks, Dave! That is certainly believable. They gave us a lot of nice stuff in our cars.

Could additional wiper speed variances occur as a result of the electrical load and voltage differences from the alternator say... Idle with a bunch of stuff on to say 40 mph?

so if the switch is on wintermode the wipers will "park" higher on the windshield than they would otherwise. but when you say "park" do you mean when they come to a rest when the wipers are still on? or when you turn them off? or both?

on my SVX with the wipers are sitting in the off position up on the windshield, i turn the switch and they make a full swipe up and come back down to rest in the out of site position. If they are in the out of site position, turned off, flip the switch, a full swipe and come back to the position on the windshield that allows them to be seen. I don't flip that switch with the wipers running. Only when they are turned off.

Hope that explains it.
Keith
