Apex Eight

Alright, so I know this topic has been brought up many times, and I've searched and found threads on them, but they all seem to end without reaching an absolute conclusion or one that doesn't seem to make sense in my situation.

I have a 1989 XE Coupe.

My situation:
- Headlights are always up

- Can manually retract headlights down
- Headlights go up if I press the headlight button on the left side of the dash
- Headlights do not go back down if I press the headlights button the left side of the dash again
- Headlights do not go up if I turn them on using the headlight stalk

- The actual lights of the headlights work perfectly fine, both high and low beams, as well as all sidemarkers and both turn signals

- I have three headlight relays in the driver-side fuse box in the engine bay shown here:



-But as you can see here in this second picture from what I've circled in red, the last two relay plugs do not have the 5th terminal like the first one does. I found this to be strange. Is this normal? If not, how do I go about getting a new terminal in there?



- I feel like this isn't normal because all three relays that I have are Nissan 5-blade relays, as shown here:





- I should also note that I was messing with the relays one day and pushed the first one down kinda hard and the headlights motors engaged for a split second, and the headlights went down like an inch. That is the first and only time I have seen my headlights go down on their own power.

- I've read that people switch out there headlight stalks for a new one and their similar issue is gone, but I've tried this fix: http://forums.nicoclub.com/how-to-fi...s-t280461.html and the it didn't do anything.

- If it's normal to only have four terminals on the last two relay plugs then I will go ahead and order a new headlight stalk.

Any input is greatly appreciated! Thanks!
