Horn sounds like wounded sheep
On my new-to-me '88 911 Cab the horns sound so bad my wife is insisting I get them fixed. I have the Bentley Service Manual which says I have to remove the front bumper to get to the horns. Bafore I do this I want to have a plan for what I'll be doing when I get to them. OE horns are apx $45 ea. from Pelican but don't want to go that route unless I have to. Can stock horns be replaced w/ FIAMM (sp?) horns (available at most auto parts much cheaper) or will they not fit w/ a 911? I saw mention of Hella Air Horns, will they fit w/ min. modifications?
Any assist. greatly appreciated,
Bill W.

Your horns consist of two Hella plastic "trumpet" style units. There is a high and low tone, one each...seems one of them is dead. 
If you just have a low tone, the high tone one is dead and vice versa.
They are accessible in front of your oil cooler, located in the right front fenderwell.
You can disassemble the unit that you think is defective and clean up the contacts...I've heard several success stories regarding that issue...or just purchase a replacement...all you need is the horn itself, the plastic trumpet piece can be re-used.
My two cents: Get the factory replacement parts...don't try and "fenagle" something, you'll just be frustrated with the sound in the end. <img src="graemlins/cussing.gif" border="0" alt="[grrrrrrr]" />

Hi:
No need to remove the bumper.
You can take off the side panels behind the rubber bellows..and then the bellows..gives you all the room you need to attack the horns.

I wish I had listened to Jeff's advice but I ordered the replacement horn "kit" that is available. The big hassle with that is the replacement pin/plug's that you have to convert too. They are funky Amp pin connectors and I didn't have the special tool required to make those connections (and no instructions either), I tried my best but couldn't make the connectors stay. Also w/ 2 of that style horns had difficulty getting them both on the stock bracket and in the cavity behind the bumper.
I wound up using the original "high tone" horn and buying a low tone FIAMM. It fit ok w/ the stock trumpet high. This works but if I had to do it over I would just replace w/ the stock trumpet.
By the way, cleaning the contacts didn't fix the original low tone horn.
HTH the next person,
Bill
