'91 CQ Power Window Relay USA to EU Swap

[Christopher Gharibo]

As you may recall, I had posted about my '91 CQ relay giving out 9V to power window switch light when the car was off. I swapped stock power window relay 286 to European relay 347 that is a 13 pin Siemens Part No. 79FA400 / 441959257. eBay has pictures of what this looks like. 

The window switch light now goes to zero volts after timer runs out. The door switches do not have any effect. The window switches power back on when the button is pressed even when the key is out and door is open. Driver express down works. But there is no express up for driver side and no express up/down for passenger side. 

Has anyone done this swap and what was the express feature outcome? Are there other relay part #s that enable this feature?
