I thought I had seen somewhere that when using the intermittent mode of the windshield wipers, the speed of the wipers increased with the speed of the car. I tried this today but didn't see any wiper speed increase. Does anyone know anything about how the wiper speed is supposed to work? I did notice that after a brake release, the wipers would activate. I think I had seen this reported also, and it seemed to work as reported.

 

Yes it does. For example, in the intermitten mode, make the timer as short as possible. Notice when you drive, it will wipe continuously. Once you come to a stop, it only wipes intermittenly.

 

Right. The speed is not going to increase by the way you said.

Check the owner manual. It talks clearly.

 

the manual makes it sound just like he said. the car just doesn't do it.

 

Let me get this straight...the wipers speed up when the car starts to move but DON'T continue to speed up as the car moves faster? Huh. After reading the manual I had myself convinced the wipers WERE going faster and faster as the car sped up. Probably just what my brain wanted to believe.

 

:smackhead

 

I checked the operation of the wipers again and here's how they work. For most intermittent settings the wipers run without being affected by car speed. For the fastest intermittent setting, the wipers are intermittent (at a slow rate) when the car is not moving, but when the car is moving the wipers run at the slow non-intermittent rate. If you read the manual carefully, this seems consistent with the wording.

 

The only setting of the intermittent operation that affects the wipers when moving is the slowest setting . At that setting, the wipers will change to low speed (LO) operation when the vehicle speed exceeds 12 mph.

Any other intermittent setting, except the lowest setting will not change the intermittent operation of the wipers regardless of speed.

 

There is another feature here. When you are on the lowest intermittent speed , stopped at a light, when you take your foot off the brake the wipers will make one fast sweep, and then go back to intermittent until the speed exceeds 12 mph.

If you want to test this in your garage or parking place, flip your wipers up so you don't scratch your windshield, put the transmission in drive , step on the brake, wait for the wiper to make its normal sweep, then take your foot off the brake and it will make another sweep right away.

 

It does that in ANy intermittent wiper setting... seems like a good idea, but have had the wipers wipe too much in start and stop traffic etc

 

You are correct. Any setting. While checking this out, I found that if you have the park brake on it won't do it. I set the brake so the car wouldn't roll back in the garage, but the wipers didn't sweep, so I finally figured out it was the parking brake.

 

OK.. enuf said about the TL's wipers ability.

Needless to say that those engineers have to work on it.

That is to say, check out a Lexus ES300 auto wiper system.

BUT it would be allot easier for Acura to dial in what the driver sets on the stalk, relate it to the current speed input and brake pedal.

But still.. the 04 TL is sweet!

Until Acura does that.. WTF, RainX works just as nice!

 

All right then, after I do that and drop kick the washer and dryer through the back of the garage, do you think I will be able to get it up to 12 MPH before I hit the swimming pool? :cop:

 

rotfl

You don't have to go 12 mph to test the "foot off the brake" part. Just a quick release of the brake will prove the theory, and then you can get back on the brake. Or go to an open area. Or follow UA66's advice. Or check it out while driving.

I know you're pulling my leg, but I am incapable of making a short reply so I have to go through the motions and then get to the point.

 

You must be related to my GF? :lol2:

 

GF = girl friend ?
GF = grandfather ?
GF = grosse frau ?

 

GF= Das ist mein Freundin, nicht mein Grossmutter.

Herzlichster Gruss,
