Another slow windows question (Mondial)

Today during a great Fchat drive out with 27 Ferrari's (see EU section) something strange happened. I used the electric windows a few times in the morning. Because of high temperatures I drove the whole day with open windows. In the afternoon I wanted to close them and they only come up for about 6 inches very slowly. Going down is no problem but comming up only 6 inches again. Strange thing it is at both sides. Left window was allready slow lately but right side was ok. Back in a quiet garage I listened. I hear the motor very good when going down, when going up the 6 inches the sound like they loose power........and then they stop...no noise.

Any ideas??
Thanks in advance.

 

same old, same old,,, not enough juice.

check grounds.
clean switches.

I am a big fan of the use of some relays under the passenger foot well.
This will bring the windows up to a needed 12V.

 

Because the both windows worked perfectly and then out of nothing they both have this problem. Where to check first? Remember I am not an electronics engineer

 

Clean your battery posts.

International auto has some 4 lug window switches. Buy a couple as testers.

Next, get a new fuse box,, or clean yours.
(What year Mondi is yours?)
Nice color too.

Oh, I see it's a 1982 same as mine?

(Post a nice pic of your interior please.)

 

If sudden onset after driving all day, may have low battery charge, especially if hot - put the battery on a trickle charger (25 EU?) and try it in the morning after all night charge. - Mondials eat batteries every couple of years - even the good ones - and the first sign of a dying battery are things exactly like this.
Would replace all the relays anyway first off.
If they are moving at all it is not the window switch.

One cold beer says it's the battery, as BOTH windows were affected at the same time after a long drive.

 

One trick to try; lube the window track felts on each side (front and back) with silicone lube spray. Amazing the difference this can make.

I had a similar problem with the driver's side window not wanting to go up all the way (78 308GTS), and the lube trick worked great. Just had to reapply every 6 to 8 months though.

 

Thanks for all replies.

a: it's a Mondial 8
b: It's a 1 year old 75ah battery, but I put it on the charger now. Will see what it does in 24h.
c: New original fuse box 3 years ago (Birdman we Mondial drivers need your input)
d: Think switches are ok because they go up and down a few inches, but will clean them.
e: changing the relais is always a good option. Will do that next week.

If it is the battery, why is everythingelse working ok? 1 year ago I changed first because fuelpump wasn't working well. After a while we found out it was the relais.

 

window track felts = window rubbers?
Can't do any damage to try it ofcourse.
Thanks.

 

b. I have had quality batteries die sooner. Mondials eat batteries.
d. Yes - I agree
e. Yes.

If the battery is that new, it may be a relay, but it would be odd for BOTH window relays to fail simultaneously. The battery comes to mind as the window lifts require a lot of Amps to lift them up (probably the highest load circuit except for the starter which has heavier cables), but not go down ("going down is no problem") and they both failed at the same time.

And now the stupid question, so forgive me - was your air conditioner on when you tried to lift the windows?

 

uh..........yes. Why?

Charged the battery but nothing changed. Just a few inches and then they windowmotors sound like they to less power.
Changed relais and fuses, nothing changed.

 

Roel,

You can't change the window relays, if you didn't do the Hot-Wire mod under the passenger footwell.

(Your New fuse box probably made that F-car sytem last this long, without the relay mod.)

I don't know if the instructions are still on this site, after the great crash.
Do a search..............

Oh, and send me a PM with your 1982 interior picture... I am working on a 1982 EURO Mondi-8... I only have experiance with a 1985 Cabriolet.

Thanks,

Mondial have a habit of dropping voltage and current, not sure where it goes, but it happens on Starters, Window motors, Headlights, Fuel pumps Etc.

1. After ruling out the battery, relays and fuses, a good next step is replacing the hard crusty grease in the motor worm gear box with a #2 HP sticky grease of your choice.

2. Window felt is also a good item to replace, but if your motors aren’t working well, doing so can compound the slow lift problem.

3. Switches while probably aren’t the sole cause, over time; the silver contacts can loose conductivity, and will drop current compounding the problem, they are the easiest and least expensive to replace.

4. Make sure you check clean and re-bond all the window circuit grounds using Stablint 22 or equivalent. There is one or two in the center console, look at the wiring schematic for their location.

5. Wiring can sometimes be the problem, if this is the case, it’s easier to install relays in the doors which bypass the cars wiring and will bring the voltage back up to spec.

 

Opened the door, took out the windowmotor.
Lot's of Dried grease inside. Cleaned it, new grease and it works again
Tomorrow I'll go to the shop for some thin oil for on the wheels where the wire go over. And some teflonspray for the windowrubbers. Still not lightyears speed but much better then before.

I read somewhere about windowmotor boosters? any link about these?

Oh yes, all above was a 1h job. Only have to build the leather and armrest back on.

 

Never heard about this and do not sure if I understand what you mean...

Will check if I have pic otherwise I will make them tomorrow for you by daylight. Thanks for help.

 

From Factory, the windows are powered directly through the switch itself. (no relays)

With the relay mod, the power comes directly from the battery, through two SPDT automotive relays, that get installed under the passenger footwell and feed into the wireharness and connect to the window supply wires. The switches then get routed to the relays #86 pole.


Oh, thats OK, I got a nice photo on line.

 

Thanks for info.
