Retrofitting heated front seats 2004 e53
My 2004 3.0 petrol is prewired for front heated seats.
Just purchased 2 seats, replacement switch panel and relay...
I have replaced the fascia switch panel...straight forwards swap. The backlight on all switches including the new heated set switches are working as is PDC,boot,hpc buttons......however despite putting in the new relay neither of the heated seat switches light up.
Is there a fuse i need to add for power ?
Will the switch not light up until the replacement heated seats are installed with corresponding connections ?
