'78 Headlight Issue
My problem is that the pass. side headlight will raise but will not go into the lock position when I use the headlight switch.
My stop bolt is not touching the frame yet.
If I loosen the 3 bolts on the "M" bracket and adjust it so that it is pulled further towards the front of the car , I can manually pull up the headlight and it will snap into the lock position no problem. ....This is without the springs attached though.... If I put the springs back on then try to pull the headlight into the lock position - it simply won't go there.
Not sure what else to try.
thanks in advance

Hi goliath1
I have had these assemblies out of the vehicle to overhaul and have a unit that will function properly.
As you already know it takes a small amount of effort to lock them into an 'open' position.
I took all 'pivot' points of the assembly and cleaned them to be free of any lubricant. I then lubricated all pivot points with 'Lubriplate' grease and flexed the unit back and forth.
Once done I had reassembeld headlight assembly with the required clearance. I knew the 'power' of the vacuum unit was limited but with the new lubrication it had enough 'power' to operate the system with success.
Good luck to you.
