When engaging the stalk to switch from low to high (H1/H4 euro-equipped), the high beams will briefly engage (.25 second) and then no headlights what so ever. This is on an 85, 4000 based car. Any hints on cleaning contacts, etc.? Thanks Rick Stamm AWS ND IT, Kirkland O: (425) 803-7910 C: (206) 619-5439 F: (425) 803-7407
