Dear Muskox37,

Hope you're well. The hex-head headlamp adjusters are available from Volvo. According to Volvo VADIS - the now-superseded dealer parts/service database - if the car is a 95 940, without foglights next to the grille, the height adjuster is Part #3534201 and the vertical adjuster is #3534202. Each item is about $10. The bottom of each ends in a helical gear, that drives a helical gear on a shaft, that moves the headlamp housing. Both pieces - the hex-head adjuster and the corresponding shaft - come as a set.

If the car is a 940 or earlier, then different part numbers are required.

If the ball is stuck in the housing, lubricate the ball with dishwashing liquid. Then, heat a small sheet metal screw and while it is still hot, turn the screw so that it sinks into the ball. Let the plastic cool completely. Grip the screw's head with a pliers. Yank or lever the ball out of the socket.

Hope this helps.

Yours faithfully,

Spook
