What is the correct part number for the turn signal switch for my 84 full size blazer. My high beams are not working when I try and activate them. The turn signals work fine as do the wipers, cruise and delayed wipers. I have a non tilt wheel. I am thinking that all I need to do is remove the steering wheel, remove the old t-signal arm, plastic housing and wiring and reinstall the new parts. I want a new arm as the old arm is faded and the lettering is gone. So... please tell me what the part numbers are that I need. I am in Korea, a buddy of mine is on leave in the states and will bring back the parts I need. He went to a few GM dealers and he is getting different stories from all three. When I replaced the turn signal switch some time ago, I ordered the parts from a jobber, told them what I wanted and it was pretty easy. Now it's getting difficult and far more expensive. Like 400 bucks expensive! Thanks!
