Even on high speed, they are terribly slow. Let alone, trying to use screen wash. Any ideas?

Maybe the first thing i would do is lubricate the arms. when i did my heat exchanger valve i was very surprised to find how dry they were.
good place to start before thinking of the motor which in the past i have lubricated many and found they worked much better as the manufacturer does not want them to last so do not offer much lubrication from new.
Hope this helps..

What should I use to lubricate the arms? Regarding the motors, I assume you would have to remove the wiper mechanism from the car to lubricate the motors?

hi. you have ball joints on the end of the arms that see nothing but rubbish from the road. good greasing with spray grease is good. th motor will need a strip down though.
you need to remove the wiper arms and then the plastic panel underneath. 2-3 torques bit screws. place on n/s due to washer pipe.
4 x 8 mm bolts and an electrical connection(easily removed) and it will need a bit of tenderness towards the o/s to pull off the pin(you will see it at the back of the motor on a rubber) and then will come free.. easier than it sounds. then strip and lubricate.
Very easy to do. sounds harder than it is. I did mine when i changed the heater control valve. did the valve and the wiper system in under 3 hours....

Passenger motor had failed, got a used one of eBay for MOT, back in February. It has always been slower & noisier than the original drivers motor. That probably did need the motor lubricated before it was fitted. Don’t understand why the drivers motor has slowed too the speed of the passenger one?
-
Hi. Am i reading this correctly or are you talking about the windscreen wipers ?
Motors ???
-
There is only one isn't there?
-
I am trying to imagine wipers going at different speeds what a tangle.
-
The front wiper motor is multi speed ,low geared ,high torque
(very strong ,like a starter or electric window motor)
I'd check voltage,make sure it has a good earth etc
check the relay
lubricate the linkages ,yes ,
but i suspect the motor is not getting full power (live =12v+ and earth =ground= negative 12v )or internal winding fault
sticking linkages and mechanisms can shear ,strip cogs etc because a good motor with good power supply is very strong
-
I had similar problem. Wipers were very slow and hardly got back to start position. Eventually wiper stopped working completely.
I removed wiper assembly and noticed that centermost wiper shaft was stuck in its frame. I had to use heat and hammer to get it out.
Used some sandpaper to remove rust/oxidation (shaft was steel and frame some aluminium alloy), cleaned all moving parts and lubricated and replaced two O-rings at shaft ends.
I used general lubrication grease that is used in working machines etc.. Spray grease wont last long IMO.
Now wipers move faster than I have ever seen.
Took about 1.5 hours, never done it before and removing stuck shaft (without breaking it) was hardest part. Worth to take it apart and inspect.
-
The thing confusing me about this thread is the talk of passenger and driver motors. And saying that one side has now slowed down the same as the other. As we know there is only one motor and linkages to the two shafts.
If we are definately talking windscreen wipers then yes ,lubricate the output spindles(circlip off ,o ring out and oil the shaft/bore). Lubricate the main linkage balljoints .
If this doesnt sort it. Check motor for voltage and remove if voltage found to be ok.
Either replace motor or open yours up (motor /magnet section ) and check brushes for length ,spring tension and freedom of movement. Clean commutator with fine emery ,ligthly oil end bearing and reassemble and test. (Blimey the times ive wrote that on job sheets !)
-
I assumed that both wipers, have their own motors? What I was saying, my passenger wiper linkage broke, so the wiper wouldn’t move. The drivers wiper & motor were fine, so I could still drive it. Had to get a replacement wiper assembly including motor for the MOT. Since it was fitted, the replacement has been noisy, you can hear the motor/rods going in & out. The original drivers wiper/motor has been slower ever since the passenger wiper assembly was changed. Now both wipers are unusable.
-
Hi .this still doesn’t really make any sence so I would advise just replacing the whole unit (motor and linkage assembly) for a known good unit .

One motor drives both wipers.

I have a couple on the shelf from past breakers, all good

When they start to slow down and eventually not move it is the linkage and the axles that mount the wiper arms that are dried out. There is no way to lubricate those axles. They are closed units.
Only way is to find a new linkage unit at the scrap yard and replace it. The motor is usually OK and need not to be replaced. Be sure that the linkage is moving properly when you get it. Once I got one from the scrap yard (mail ordered) that was even more stuck than the one I had on the car. They sent me another one with out charge.

Umm, how I then managed to diassemble those axles from mountings, clean them, lubricate them and reassemble them and now my wipers move faster than ever?

Good for you :y

Driving back in the fog, has the wipers in intermittent. After 5 mins, that got slower & slower then stoped. Started working again after about 10 minutes. Tried all settings & they progressively get slower & slower till they stop again. Is the motor getting too hot & over stressed due to the extra power needed to move the blades? The passenger motor failed last year, drivers still worked fine. After the passenger motor & arm was replaced for the MOT, with one from EBay, both wipers have been very slow & struggle to move the wipers. Any ideas?

There's only one motor to work both wipers

Ok. Which side is the motor attached too? Drivers or passenger wiper? Cheers.

What I’m trying to workout, is do I need a new motor, or another wiper assembly?
-
Either way, you'll need to remove the motor/mechanism to test ;)
There's a guide...

I’ve already replaced the mechanism. As you say, the motor runs both mechanisms. So can I just buy a replacement motor, which will then run both wiper mechanisms properly?
-
One motor/one mechanism ::)
-
One motor/one mechanism ::)
Your second hand mechanism has failed... Did you supply/fit it or did a garage? If a garage get them to fix it properly.
-
But I'd replace the whole motor/mech assembly. There is a single motor, and the mechanism drivers both wiper spindles.

That is what I bought for the passenger side, as it had stopped working. I’ve never had any issues with the driver wiper, until the secondhand complete unit was fitted. So do I need to buy another complete assembly with motor, for the drivers side?

Not rubbish, just old and used up like a lot of previously dependable parts on these cars.
But you're breaking the first rule of efficient repairs: you are assuming that the motor is at fault without doing any proper diagnosis.

It was replaced in March for the MOT. I’m reluctant too spend anymore money until the next MOT. Is there anything else I can do in the short term? Lubricant or new wiper blades? Or even disconnecting the passenger wiper, so the drivers wiper works properly a full speed?

remove the whole mechanism and inspect it, the motor and the wiring. Then you can decide what, if anything, you need to replace. Lubricating the linkage wouldn't be a bad idea. That's probably true for all the remaining Omegas

Nick, too clarify the motor & assembly is one piece which runs both wipers?

The motor is replaceable seperately because it screws(marked in red) onto the aluminium plate. It drives both wipers through the linkage(the green and yellow parts).

I doubt you'll be able to buy a brand new motor, if you actually need one.

Do you think it is more likely too be the motor than the assembly?

The linkage tends to fall apart, which gives a different problem than just working slowly.
But, and I'll keep saying this, you need to inspect the parts to diagnose them! Guessing(or hoping) is a waste of time and money.

That is what made me think it is the motor struggling to move the wipers, then overheating. Which is why the wipers work slowly again, after it has cooled down. Looking on eBay, there are no motors available, I’d have too buy the whole assembly again. I’m not mechanically minded, I’ll have too get my mechanic too have a look.
-
FFS this is painful...... why don't you just pop the ball joint linkages off to see if the wiper spindles turn freely? You will probably find the motor is okay, just need the spindles removing, cleaning and greasing :y Properly!

After the wiper arms have been removed from the spindles, there are just 4 hex headed self tappers that hold the whole assembly in place.
I know that Omegas are very thin on the ground on the road let alone scrap yards, but buying in person is always best. On first glance, the wiper motor of an Astra G looks the same as an Omega's :-\

I think I might be able to manage that. Cheers, I’ll update when I’ve tried.

I'd leave the ball joints alone, as they tend to fall apart regularly after disassembly. Undoing the nut on the end of the motor spindle doesn't have this problem and is much easier :y

Can any other member confirm that the Astra G mechanism will fit my facelift? What years are the Astra G?
-
Noone said it would fit, merely that they look similar...
But to answer your question, '99-'03 should avoid confusion...
-
Will the mechanism fit? Not a chance.
But an Astra motor might fit the Omega mechanism.

Thought I’d give high speed setting ago & see how long the wipers lasted. Got 5 minutes, then they stopped. Left the wipers on high speed, they came back after about a minute, worked for a couple of minutes, then stopped again. Could smell an acrid smell in the car afterwards. Do guys think this is definitely pointing to the motor overheating?
-
Or the mech stiff, causing motor to overheat

If the mech is stiff, is there anything I can spray on the arms & mech?
-
I forgot too say, how noisy the mech is in operation compared to my old mech. Maybe, they do just need lubricated. But what with?
-
Or the mech stiff, causing motor to overheat
More than likely the mech is stiff. I've come across this problem a few times on Omegas, and in one instance had to knock 7 bells of sh1t out of the shaft just to free it, whilst turning it with a 12 inch adjustable spanner - you wouldn't believe how rusted up the shaft was, and I'm amazed that the motor managed to keep it running, albeit slowly.
Back to basics methinks, and forget about the smell, just make sure the spindles are free to turn in their bushings before you go any further. I think I might have mentioned that before :-X
