2005 D5 wiper problems
 

Good evening,

I'm banging my head with my 90's wipers, all fuses checked motor is good, the control module under the dash is good as I've tested it in another vehicle by bridging from the intermittent relay to the high low relay o can get the motor to move,

However I am not getting any power to pin 85 on the high low relay!! But I am getting high resistance to earth through that pin aswell so I'm guessing an open circuit to earth on that power in line,

What am I missing, any suggestions on where to try next? Or anyone have the issue before and been able to rectify?
