1991 Cadillac Fleetwood - Answered Questions & Fixed issues

Question edited for clarity. Question moved to model category. It is hiding inside the fuel tank, and the fuel tank has to be removed to get to it. What makes you think it needs changing? Did you test the pressure? https://www.google.com/search?q=1991+cadillac+fleetwood+replace+fuel+pump ..

Where is the starter relay switch on a 91 Cadillac Fleetwood

The ABS module may have failed - check for trouble codes (DTCs) with a good OBDI code reader.

A few possible causes:

1. Bulb(s) burned out;
2. Defective door jamb switch (can usually be fixed with a few squirts of penetrating oil into the switch);
3. Defective lighting delay module (located under the dashboard, near the center on the passenger side);
4. Fuse burned out;
5. Evil spell.

You probably disconnected a vacuum hose that didn't get reconnected. The mode doors are controlled by vacuum and the default id the defrost mode.

-Do it. You need help...? Good Luck mai

Could be a blowen fuse

Click the "Need help?" link on the Gmail sign-in screen.

Right hand side (passengers side) behind dash.

Try autozone website. You can sing up with your email for free. You can select your car and then go to troubleshooting. They even have wiring diagrams. They don't have repair help for every car but it's worth trying.

sounds like a short

Do you have normal compression, spark, and fuel pressure ? Will it try to start if you spray starting fluid into the throttle body ?

My career24 password doesn't reset, I've tried using the given link from my email. But still no changes.

check light bulbs make sure they are the right number then check plugs for corrosion or could have a broken wire in casing

UNDER THE CAR ON THE SIDE OF THE MOTOR

The Relay is in the Fuse Box. FAN#1 and FAN#2

Fuel gauge may be the problem, but may also be a short in wires going to fuel gaugeBattery power goes to gauge in dash then to resistor in tank to ground. If the wire going to tank is shorted to frame it will always read full. Test this by disconnecting the wire going to the tank. If it goes to empty then you know the reason, either resistor in tank is bad or wire shorted..

Have you checked to see if the headlight switch and dimmer switch for power on both low and high beam circuits ?

More than likely the spark plug wires are causing this problem

Unfortunately, I do not have any iformation that old, and because the car is 20 years old, something like just a fuse cover is probably not going to be found on the web, it could turn into a headache. However, I have some suggestions that mayhelp you.The information you need is also in the owners manual. I have seen owners manuals selling on Ebay for $10.You could go to a junkyard and get either a fuse cover or an owners manual. The years that should be the same are 1990, 1991, 1992 and 1993.If you intend on keeping the car and want every type of diagnostic information for the vehicle, you can get a subscription to http:// www.alldata.com for about $25 a year and download every factory manual and you can access that information for a year.I make no money for plugging that site. It is just where I go when I need information on a specific vehicle.You did not state the reason for knowing where the horn fuse was located. Sometimes they are seperate, but more commonly the horn will be on the same circuit as the dome/ cigarette lighter.If you have a test light you can determine if power is going to the horn by having someone push on the pad while you are checking power at the horns. If you have power there you have bad horns.A bad turn signal switch inside the steering column could be the problem. Very common probls were horn pads (air bag).If you press on the horn pad and just hear clicking, the problem is not a fuse
