my answer didn't really express what i wanted to get across but oh well i think you got the point.

HUD STUD

Have you verified the HUD still moves when you adjust up down button?? the Hud control has two switches, 1 on/off brightness, 2 tilt up/down. Both are electrical. If it still tilts but not enough for you to see then ITS probably a mechanical mount problem.. If it doesn't move at all its electrical related.. Look down from outside the the windshield.. if it moves when you move the tilt button then it a mounting problem.. Good luck

HUD IS COOL / MY WIFE HATES IT / " MUST BE A GUY THING"

The up / down adjustor is the one that I am having troubles with. The dim / bright control works well.

When I first received the car, the HUD adjustment did not work. I put pressure on the lever as I pushed it up / down and the HUD did move, and of course, I played with it one more time and got it out of position. It must be mechanical connection between this lever and the location of the HUD projector / unit, but to date I have not ripped apart the dash to figure it out. I thought that I would try this site for answers first, which I'm glad I did.

Thanks for the suggestions. I'll have to look at it closer.

Still, if anyone has an answer, please reply. THANKS!

I was under the impression that the position adjustment was purely mechanical. Somebody argue with me.

I won't argue with you , Will. It is mechanical. The momentary rocker that adjusts the HUD controls a small motor in the dash that rotates the unit. It sounds like a connection problem, but I wouldn't rule out a bad switch or motor. Easy test: Get a cheap momentary rocker from Radio Shack. Attach test leads to the old switch to bypass. If it works, return the Radio Shack piece and get a new switch for GM. If it doesn't, return the Radio Shack piece and get the book out. It'll be a long day in the dashboard!

Maybe it'* just me, but when I adjust my HUD (after Josh goes for a joyride to the auto parts store and comes back with less of my rubber than when he left), I'd swear I feel a mechanical 'feedback', as if it were cable controlled. I guess I'm wacko. I believe you, Comp, but now I'm gonna go pull that switch off to convince myself.

OK, The tilt mechanism on the newer HUDs are controlled by a motor. But the older ones (Like 92 and 93) are not. There is a slide-lever attached directly to a cable, similar to the relationship between your accelerator pedal and throttle body.

55555 has the older non motor-controlled in his.

I would guess that 55555 is having the same type of problem that one might have with a sticking or detatched accelerator cable. It may need some lubrication or need to be reattached. Either way you'll have to open up the dashboard.

Thanks, Fud. Now I know I'm not nucking futs. At least the green bonnies can still think straight! That dash rip might not be too bad. Just pulling the cluster might get him in there.

Sorry, guys, I'm always thinking about the later models since I dumped my 89. Thanks for the correction.

I just had a similar problem with my '92 SSE */c. I recently noticed that the HUD control wasn't working. When I moved the position control up or down, it slowly returned near the center position all by itself, as if there was a gooey spring inside.
I could only see the HUD reflection in the windshield if I leaned fully forward in the seat and looked as far forward near the base of the windshield as I could.

I removed the lower dash cover but to my dismay I wasn't even able to see the HUD control cable behind the dash because of all the other stuff under the dash. So I removed the front dash panel cover and removed the 2 torx screws for the HUD control panel, and I was pleased to see that the cable was still connected but it was binding in its sleeve and was slightly bent. That explained the slow auto-return behavior that it was doing. I carefully bent the cable straight, then lubed the exposed area of the cable and sprayed some penetrating lubricant into the opening in the cable sleeve and I was then able to adjust the HUD up and down without any problems. Boy was I glad that I didn't have to disassemble the dash or remove the instrument cluster to get to the end of the cable that connects to the HUD mirror.

I hope this helps.
