Thats similar to the problem i had on the expedition. The horn would work with the key fob, and would work with the car off(never figured why car on/off made a difference). check that connector and possibly the ground to the cruise control moduleACV1081 said:OK, swapped out new servo today and still no luck. I noticed the connector that plugs into the servo is very corroded and I may try to wire in a new one. If it matters, I have the horn working when I set the factory alarm with the keychain remote. I really want the cruise, but the car is just not safe without a functional horn. Thanks for the replies and keep em coming.

Hummm... my horn will not work in the car regardless, on or off. I checked the connections to the horns and they were fine. I am thinking the connector (to the servo itself) is causing the problems, but after swapping springs/struts, O2 sensors, and doing cam seals and a timing belt all in the last week on the 95 I am sick of working on it for awhile. Not to mention swapping in the new clockspring and black steering wheel. This is why I loved my 93, the maintainence was done and reliableCheckerSHO said:Thats similar to the problem i had on the expedition.

Damn wreckless & uninsured people. 
The fact that the horn works with the keyfob means the circuit between the horn relay and the horns is ok, and its a matter of the horn button not grounding the horn relay for some reason.ACV1081 said:Hummm... my horn will not work in the car regardless, on or off.

As noted in this- http://shoforum.com/diagrams/1995/9506.pdf diagram under 3.2SHO...The switches in the steering wheel are ALL grounded thru the cruise control module, so that corroded connector is probably your problem
ThanksACV1081 said:Thanks for all the help... I bet $ that connector is my problem too. Good thing I have another laying around. I love your mods and color combo SHO checker
That sucks about your wreck...that was a sweet looking car. At least it saved you from major harm
