R129 1994 - IDENTIFY A DIODE in roof controler

Hi everybody - newbie here with a problem

R129 1994 older style roof controller

working through the Pcb and found x2 diodes that seem to be dead (reading both ends when meter set on continuity

there are no numbers on the 2 orange diodes -searched everywhere i can to
find their values (even contacted suppliers) but cannot get the values of the diodes (orange) I have ordered a pack of various values ,but need help as I dont want to damage the board (roof works/roll bar works but no windows (replaced the relays)

any help would be greatly appreciated as pulling my hair out

hello again - fitted new diodes and they burnt the copper strip


replaced the diodes with correct ones and it heated up the copper strip they are attached to

so I think the way forward now is to rewire the windows off the board as initially thought

any advice please how to do this i now have all the wiring diagrams just need to know how to go about it - this is 94 but does not have the auto drop windows its the old style
controller temic 129 820 2526

Hello anyone who is following

managed to wire the windows separate from the roof controller

bit of a job but saved buying a controller - 4 relays and a bit of wire switching on the window switches - job done

I was following but I couldn’t offer any advice. I wonder what happened to smoke the original diodes and traces. Good thing you were able to hack your way around the controller.
