Replacing 1265420132 Lamp control relay - light control module

[550Maranello]

Hello,

I replaced the light control module - 126 542 01 32 - in my '93 500E. All the lights [interior, high beams, turn, hazard including the radio] work but NOT the light beams, rear and brake lights.
I put the old module back and the same thing happens, the car starts and runs well but I can not drive the car the way it is.

Any help.

Thanks much in advance.

I'm having same problem with my w140 lighting module.Been suggest dealer can repair it or paint contacts with metallic paint so pins fit tight
