I know this has been discussed before, but I cannot find the threads.

My 84 GTV6 windows go up / down VERY slowly. I have recently replaced the ignition switch and several years ago the alternator. These changes have not affected the problem.

Can anyone provide advice or links to past discussions?

There was also a discussion of protecting the ignition switch with a relay. Is there a link to that thread?

Thanks in advance!

My son Mike and I put a ton of work into the windows on his '86, with limited success. What helped was:
--cleaning & lubing cables, pulleys and pulley pivot bolts, motor cable spool
--unplug all electrical connections, spray with electrical cleaner, reconnect
--replaced both window relays in fuse panel, sprayed sockets with electrical cleaner
--cleaned and lubed window felt tracks with silicone spray
--made sure window was aligned in track, that it was not "walking" on its way up
--removed switches in dash, sprayed plugs/terminals with cleaner

Even so, the driver side works much better but not like a new operator, and the passenger side only works well in warm weather. I think the motor's weak on that side, frankly. We're considering replacing the assembly with the new type tracked window winder that has been used successfully on the Spiders. But they're $250!

On the topic of wipers, we have a relay set all wired up and ready to cut into the wiper motor wiring. One high, one low speed. We'll tap into the 12V terminal on the firewall there where the lead drops down to the starter. We're going to remove the motor, clean up the gearing and switch tracks, relube and reassemble. New wiper blades, Rain-X the windshield, and then we'll see how much they're improved. I predict it will be worthwhile, and we'll report the results.

The enemy is voltage drop... and poor grounds. You want good clean connections and solid grounds. Oh, and a good battery!

I have been driving Alfetta GTV's since 1980 and have found that Alfa put in 45 Amp alternators in there cars, but through the years kept adding stuff like radios, AC, power windows, etc. without thinking of power output. Yours is probably 55 or 65 amp and you can easily add more power with little investment. Report your findings.

I will check the alternator output.
Put relays where ever is possible and that will solve your problems.
My opinion is that the all problems are caused by fuse box.

So there are two solutions:
1.Change fuse box with a more modern one
2.Install relays

Of course your alternator has to have steady load around 14.2 volts at idle.

Below is my story.

My 1985 GTV6 has a relay on the ignition switch, and heavier wiring to the window regulators and relays plus an 85 amp alternator. The windows work very well.

My passenger side window is slow. I hooked a 12 volt battery directly to the window motor and it was still slow. In my case the problem is definitely in the motor/regulator.

This is excelent test and a good starting point.
