I had two things driving me crazy on my 95SSEi. I did some searching but really ended up fixing them with my own dumb wits.
The first: Huge wind noise- like a window was down 1/4 inch or something. REALLY LOUD.
The second: Bad, bad squeak - so loud it can interrupt a conversation in the car.

Forum seaches pointed to door weatherstripping for the wind, which I spent weeks going through with no success. I accidently found the culprit. The windshield trim that snaps around the seal had come unsnapped at the top of the windshield by the roof. You couldn't really see it, I noticed it washing the car. You could snap it back down with a whack from your palm, but it would come loose in a couple weeks. One day I snapped it down and got on the highway and the wind was gone. Whew! I glued it down with some weatherstipping sealer.
The squeak is from the hood latch. The secondary safety catch rubs and causes this loud squeak. If I put grease on the hook,where it rubs the catch bar, the squeak goes away for about three weeks then returns as the grease disepates. You can make it squeak by bouncing the hood (while latched all the way) which has just enough give to allow the secondary latch to rub and squeak. It'* bad. I need advice on making the primary hood latch tighter or putting something over the metal hook to cushion the metal-to-metal contact area.

My hood latch does the same thing. I tried the adjusting the height of the adjusters that hit at the front corners of the hood, but that didn't help. Lubing lasted about as long as yours. My low tech solution has been to wrap electrical tape around the loop on the hood.

I use plastic wire ties. last longer than tape and grease

I was going to suggest adjusting the tensioners, but apparently that doesn't help per Dick (Archon).

How about the tension spring in the center of the hood. One thing I've noticed at the parts yards is that many are missing the little rubber cap that goes on the end of that spring and keeps that part from rubbing on the hood. We dubbed them "spring condoms"...

If yours is missing that, it MAY be a contributor to the squeaking sound.

The latch assembly can be adjusted up and down if you remove the radiator support cover.. there'* 2 10 mm'*

I actually covered the top of that spring with tape, didn't help. adjusting everything on the latch assembly didn't help either. isolating the squeeking metal pieces is the only thing that worked for me.

The spring condom is still in place. The rubbing of the safety hook has actually worn a notch in the metal on the leading edge of the hook. Maybe the notch contributes to the squeak and I can adjust it up or down to an original smooth area. The hood itself has almost no movement or "give" in it when it is fully latched, but I could try to make it even tighter. I played with the adjustment of the latch side but couldn't get very much movement to change the overall contact lineup. :?

That safety latch can also be adjusted.

Yep, I had tried all those things, without success. Skregal, if you haven't already, at least give all the adjustments a try. Better to actually fix the problem than cover it up. If/when all else fails, you may need to go with Travis'* (sonoma'*) fix. While mine has lasted a couple of years with the tape, I like his solution better.

Travis, did you need to make other adjustments after applying the wraps due to their thickness?

no, by the time I figured it out, it had made "the notch". just clean the notch with you dremel so the tie fits in it. if you use a wide tie, just make the notch wider.
