SOURCE: Where are the cooling fan relays for a 1998

Are you sure that you don't mean the cooling fan control module? It should be located up front next to the cooling fan. It is square shaped and has a long square shaped plug going into it. 00114_cooling_fan_control.jpgReads the temperature of the coolant and passes the information to the engine control computer (ECC). The ECC receives analog information and signals the cooling fan switch to cycle the cooling fan on or off, as required.

SOURCE: 1988 Ford Crown Vic Horn Relay Location

The horn relay IS NOT located in a box toward the front of the engine. It is located just behind the radiator overflow reservoir and attached to the inner fender next to two other relays. It is the only one without a plastic cover over the top of it. FYI, our Crown Vic horn didn't blow, and the cruise didn't work. I changed the relay and still no horn. I decided to check the horns themselves. Found wires disconnected from terminals. Touched wire to horn terminal and horn blew incessantly. (previous owner had disconnected horn rather than diagnose why) Pulled the horn "button" from steering wheel and disconnected the wire leads and horn quit. Disassembled the "button" assembly. Foam had degraded over time between the contacts. (Ford has discontinued this part). Cleaned and replaced foam with Scotch foam mounting squares with holes punched out over contacts (2 layers thick). Re-assembled and viola! Horn and cruise control both work! Relay was bad as was horn button.

Disconnect horn 1997 cadillac deville


The 'A' and 'F' note horns are located underhood at the front right corner of the vehicle. To "disconnect" the horns, pull off the electrical connectors or remove the horn relay in the underhood fuse block. If they are on continuously, consider replacing this horn relay, but the problem may be in the steering wheel assembly.

I have a 2000 Cadillac deville, I thought the battery was dead so I jumped it, but know the horn wont cut off is it the battery something else


You could have a couple of problems. The antitheft system could be making the horn sound. Especially if the horn is not steady, but an off/on cycle.

Years ago, and we are talking about a 1967 model, GM put the horn relay inside the starter relay. If they still do that on some models today, I can not say, but you may try to trace the wires from the horns back to the power source.

You can unplug the horns, but it is dangerous and illegal in some states to drive that way.

Anyway, right now you do not know if the antitheft is making this happen or if the Horn relay is stuck .Check with an autoparts store for your horn relay and see what it looks like. You may want to change it.

Remove steeringing wheel in cadillac 1988 sedan deville ?


The steering wheel should be turned so the wheels are turned straight ahead before you start
the work. And the wheel should be locked so you can align the wheel correctly when
re-installing.

1) Take off the two 8mm on back of steering wheel that hold on the horn pad. Twist and detach the
connector/wire that goes to the horn. Remove the horn pad.

2) Remove the nut and retainer holding on the wheel.

3) Use a steering wheel puller to remove the wheel. You can get a loaner steering wheel puller from
autozone.

So why are you removing the steering wheel? Let me guess, the wheel is loose?!

I need to know where a few fuses are: the horn fuse, the cigarette lighter fuse, and the radio fuse.


The fuse box will be located on the drivers side on the firewall. The fuse for the cigarette lighter is the one marked with DM and the radio will be marked RDO.
