Window Switch interchange

Finally got around to cleaning up the switch for the passenger window (common to the drivers door) on my '78 308. The window moves pretty fast so I thought I would clean up the switch on the passenger door also. The window doesn't move.

I will be checking voltage at the switch this afternoon but in the event the switch is unusable is there an equivalent/after market type switch that can be used in it's place or am I stuck with used or NOS Ferrari?
Thanks in advance, DJ

DJ,

I'm not aware of any aftermarket switches that look and fit the same.

If it ends up you need a new switch, check prices with Jeff Howe @ Ferrari UK, thru the Ferrari Owners site. The prices and service can't be beat.

No voltage to the switch so I may have to pull the door apart to check the wiring. Fuse block checks out too. Bad/dirty connector somewhere methinks.

I just ordered some lenses from F of U.K. and they were very helpful in insuring I got the correct pieces. I had supplied the wrong P/N's and they caught it before they shipped. Great way to do business.
Thanks for the info, DJ

DJ,

The motors operate on a 2 wire system with a common ground. + on one up, + on the other wire down.

I'd recheck the fuses/relays for the source of + loss, or the Drivers door master switch.

After running tests on the fuse block and switching relays I think the Driver's master switch maybe a good call. I'm going to study the schematic some more so I can get a better idea of the convoluted routing of the system.

Thanks for the tip, DJ
