hey, i have a problem, my low beams aren't working but my high beams are. Now i have read a little into this and im having trouble isolating the problem. I dont think its my combination switch because i opened it up and cleaned all the contacts. Now im thinking its either a common ground wire or a relay problem, but how can i tell which? Where should i have power? And is there anything else to look for? Thanks.

Is this on your 1977 Accord? Or your 72 Pinto?
