Ferrari Window Regulators

Since I was old enough to hold a wrench, I have been repairing Ferrari cable operated window regulators and have tons of scars on my hands to prove it! Like the Bizarre-O cable operated Maserati Ghibli Water Pump design, this is an equally offbeat way to make a window go up and down. My rant is “these guys has no right building cars”. Whats the deal with Italians and cables?

This cable has to “spool up” and “un-spool” around a drum simultaneously as an electric motor turns it.  If the cable isn’t in perfect condition, it can fall off the pulleys or make a horrible grinding noise when operating. The smallest bend, kink or fray makes the whole system come to a stop. You can get complete new assemblies but often the cable is wound tightly during shipping that it  causes problems so I rebuild them with new cable that I have in massive quantities here at the shop.

A frequent problem with these systems is super slow motion of the window glass barely making it to the closed position.  People have all sorts of hair-brained ideas on how to fix this problem but the issue is simple. The green grease in the gearbox gets hard like wax and the motor can’t overcome the resistance. If the cables, pulleys and channel is in good shape simply zip tie the cable to the assembly which maintains the tension and remove the assembly from the door. Remove the 3 screws to the hold the gearbox together and chip out the green wax (that used to be grease).  If you are lucky, you won’t kink or loose the orientation of the cable and can get it all working in 20 minutes!

Waxy Green Grease to Chip Out

I use a synthetic grease that won’t hurt the plastic housing but make sure it has decent rust preventative, there is a ton of moisture that builds up in these doors that will seize the gearbox as well.
