No horn in '94 Jeep Grand Cherokee

No one would have any way of knowing what you did or why

And without a wiring diagram, you have no way to familiarize
yourself with the problem

Get yourself a set of factory wiring diagrams,
otherwise your wasting your time

You have no idea what you working on, without
reference material

head over to the salvage yard pick up a new manule for 5 - 10 bucks

Horn relay switch or faulty horn.

MOST LIKELY THE CLOCK SPRING ROTATING CONTACT UNDER THE STEERING WHEEL IS DEFECTIVE/OPEN.

get a 12-volt tester and check the wire going to the horn to see if there is power going to the horn if it is the horn maybe bad check all fuses first i hope i have been some help to you Michigan man.

My 97 Jeep Grand Cherokee was doing the same thing. I changed the TPS ( Throttle Position Sensor) Now it is great goes into overdrive fine. It is really easy to change.

no it wont work.they made too many changes with them about 2 years older and id say yes but no they wont interchange

The only thing that can make the noise is the transmission front pump, if the trans works ok try changing the fluid and filter, it may help or reduce the noise.

could be anything overcharging the system, freon leak faulty componets like compressor or clogged lines or orfice tube or dirty evap. coil check for 12 volts comming into the blower motor with ur switch on high if ur getting 12 volts at the plug then replace ur blower motor
