intermittant wiper relay

stu · Post by **stu** » Thu Jan 29, 2004 5:34 pm

can anybody tell me which relay is for the front intermittant wipe and which is the rear, because my front intermittant wipe does not work, I was hoping to swap them over.

did you probably refit your acceleration cable?
the wipers are controlled by the CEM, changeing relays won't work

As above post says, changing accelerator cable often causes intermittent wipe not to work. See main club site FAQ. http://www.volvo-480-europe.org/cardata/faq/faq.html

yep I agree... What michael means is that back then, as new, as switched on intermident, and flooring the car, it automatically switched over to fast wiping.

the front and rear wipers are in several ways connected, like working at the same time, (to prevent nervousness as volvo states) and working as in reverse.

download the electrical schedule and check the items in this circuit. It is a big chance its this switch on the throttle cable assy.

Not knowing all this years ago i bought a intermitend switch relay with a turnknob for timing and build it in. It adds some luxerory but i liked the original setting better

Where is the switch located?

remove black plastic panel above the pedals, sit with your head where your feel normally are(don't blame me if your back hurts

), look up allong the throttle pedal.... it must be there i was told. Use search machine, was discussed well before

The cars were fitted with a feature where, if on intermittent wipe, you floored the throttle pedal the wipers would turn onto full wipe.

This was operated by a switch on the throttle pedal. At some point, Volvo removed this feature and any replacement throttle cables don't have the switch built in to them.

The lack of intermittent wipe the wipers (mine acted as if they were switched to position 1 when intermittent was selected), is caused by the wires which would have originally been connected to the throttle cable switch being connected together, fooling the wipers into thinking the throttle cable is fully depressed.

As Volvofox has said, you'll need to lie on the drivers seat (upside down!), to look up underneath the dashboard to find the offending wires.

Someone had done modification on mine car. It has no switch ona trotle cable (gues it was renewed) and the wires wich goes to the switch are connected together. My intermittant wipers work.
I had a Volvo 345 for some time ago with CVT transmition, there was a switch on throtle cable for controling vacuum valves for a variomat. But this cable is a lot different then 480's. Maybe one could install a microswitch on a throtle body?

bYe!

You're right bbf, I got it the wrong way round... Oops

According your experience , should we connect together these wires to recover the intermittant wipers ?

I'd guess something is wrong in David case

......may wires look connect and aren't ?

your advice

The wires should be connected to make the intermittant wipe work.

bbf: i know some of this, i have a daf coupe with the same variomatic as a 340. but your 345 wasn't either a 2 liter, or it wasn't a variomatic. As far as I know a 345 is a two liter with the great longstroke swedish two liter engine. to my knowing it never had a variomatic, since it could not cope the forces. I had two 340's one hatch and one sedan, both with 1400's and available with variomatic ... explain ?

my daf has indeed a microswitch at the carburator (throttle) to handle the vacuumswitches that handle the "braking on engine", "mountain brake" or just plain shift down

If I am not mistaken Gerrsvolvo also knows a lot about the great variomatic.

mine is 1981 345 GL with renault 1.4 (B141E) engine and DAF variomatic.
I still have it. (but it is not on streats, will be restored soon).
I got an original CVT service manual from one nice person in Gotheburg (mailed me on his expences!) when i got trouble with CVT. There were 2 versions of full throtle switch (one on carburator - very early model, and on throtle cable - others) and 2 different shift levers - one earlier ugly old BMW like and one nice smooth like in mine. They also changed weights in clutch in some year - don't know when (must look in service manual).
and DAF did not have a differential in a transmission, the difference was compensated with "slippy belts". That's why DAF only made 20.000 km with one pair. CVT on a 3xx did 40.000 by factory recommendation but people did even 80.000. I had newer changed them and made 40.000km with it (don't know for his early servicing) and it still runs like the first day i've bought it. i only shifted primary an secondary units apart a little to get more tension on belts.

i'm off topic again..

Have i talked about 2 litre? Maybe the throtle body quote misslead you. I ment on a 480 to add a switch on it and connect to those 2 wires wich shul go on throtle cable switch...

bye!

Hi everyone, my first post.

Picked up my new purchase, 480es 1989 1.7 auto, only 48000 miles, last week but been waiting for some daylight to start work.

Done some searching so was able to sort the long distance lights not working as they should at the weekend, was the switch by the heated seats. Also took lights out cleaned and resealed them.

To my problem and the reason for resurrecting this tread, the front intermittent wipe is not working, it works at normal speed, having searched found this tread but having looked at the throttle cable by the peddles it doesn't seem to have a switch (my back not too bad

) so maybe previous owner had new cable fitted.

In case it does still have one here exactly should it be?

What does it look like?

And if it has been removed what colour wires am I looking for to connect together?

Having read above believe it’s that way round and not wires to separate.

Any help would be gratefully received.

Yipee !

someone who does a search first !!!!!!

Done some more digging and managed to sort it out.

So for anyone with the same problem, or who is interested.

My age of car had a switch at the end of the cable (believe it was round and white with two spades) but it had been replaced at some point for a later cable when this feature was controlled by the ECU.

The wires that used to be connected to the switch need to be connected together or the intermittent wipe won’t work.

The colour of the two wires are white/brown and brown, they also have different spade sizes!!!!!! (on my car at least).

Until today I believed that the 480 didn't have an intermittent front wipe function. As on my car it is either on or fast.
I don't know if it's a fault with the switch on the throttle cable like mentioned in this thread or if its the stalk. The reason I think it might be the stalk is the there are only the two positions On or Fast, there is nothing before the On, but there is a lot of travel before reaching this position. Is this how the stalk is or is the intermittent position broken?

Also the rear wiper in position one only wipes once, in position two it wipes intermittently. Is this also normal?

I should mention that my car is a 1993(L) 1.7 480S.

Thanks, Ashley

the intermittent front control is up on the stalk. from off position should be , up-intermittent, down normal, down again fast.

intermittant--------------- up 1
off ___________________________________stalk in middle off
on slow---------------------down1
on fast---------------------down2

the rear just has 2 intermittant speeds. you probably didn"t wait long enough on slow.

Slash01 · Post by **Slash01** » Tue Feb 25, 2014 3:12 pm

thanks, I'll give that a try. Didn't think to go up.

Slash01 · Post by **Slash01** » Tue Feb 25, 2014 7:42 pm

I can report that all my wipers are working as they should.
Strange design to go up for intermittent then back down through off to turn them on. And as a result I'm now the laughing stock of all my friends.
