hi there, I have got an issue with my elec windows & sunroof. I know windows fault is common and I have been pointed to the double relay 343 in aux panel (under driver dash).
I have removed and taken cover off relay to check it out. it has 3 little relay coils inside it. At a guess one is for ignition, second is for sunroof and other is for window motor switching. It looks clean and i re soldered any cracked or poor joints
from schematic....
I believe that when you turn ignition on there should be 12v at relay pin 4/61 and when engine running 12 (14v) from alternator. I think this 12v should then pick up one of the coils in this relay 343?? that then puts power out to door switches and motors on pin 8/87 (Q10 connector)
I have no volts at this pin with either ignition on or engine running which makes me think I have a crappy or loose connection at either T2c/1 or A17
if I manually close up the right hand side coil in relay 343 I have power to pin 8/87 and operation of windows and sunroof. I am also unable to get the relay to energise using my own separate battery supply, a friend has an unproven spare I can try but I still believe there should be 12v at pin 4/65
I suppose my question is does anybody know where both T2c/1 and A17 connectors are please or what they look like?
what do the connections with capital letter (A17 for example) look like?
also If somebody could explain the door switch function from the schematic please ellaborate
many thanks guys, its bugging me now
