Question about 1984 Jeep CJ7

1 Answer

My headlights suddenly stopped working. I assume it's a blown fuse. I have an old 84 cj7 that I do not have the manual for. I'm trying to find out which fuse is responsible for my problem.

Don't have a diagram for that one but I'd begin by checking power and ground at lights and power on the "out" wire from the switch, and work towards the middle. Also check power distribution center and see if there is a fuse, relay or both for that.

Where do I locate the fuse of the headlights in a 1984 jeep


Don't believe there is one for headlights. Your jeep is too darn old: I can see wiring diagrams going back to 1986 at a site, so I looked at one for an '86 CJ7. Unfortunately not a complete headlight wiring diagram, however, so you're getting a two bit answer, with inflation worth about 10 cents. lol.

The headlight switch gets power from a fusible link (Fuse link A) that looks like it may be located on the starter solenoid terminal- two fuse links- A & B, there somewhere. But this same fusible link A also supplies power to the fuse block with the park/tail lamps, hazards, brake lights, and a couple others. So if you have stop lights and park lights, then the fusible link is good, so you should have power to the headlight switch. Neither the fuse block, nor the instrumentation diagram, shows any fuses for the headlights. A lot of older vehicles did not have headlamp fuses, because the light switch had a built-in circuit breaker.

My guess is you have a bad dimmer switch, or the connection there may be bad. Or check if you have power to the headlight socket with the light switch on, and if you do, there may be a headlight ground problem.

Could be just fuse blown, or headlight bulb blown, if both ok, check headlight contactor.

What would cause a 2000 VW Beetle's headlights just to stop working? Everything was fine Wednesday. On further inspection we have found out that we don't have a horn, headlights, blinkers, windshield


recheck the fuses, use an ohm meter that"s the only way to be sure.
if the fuses are ok do the same with the head lights.
a blown fuse is the only reason i know of for such a sudden loss of all the things you mentioned.
hope this helps

Why the rear end tires on my 84 cj7 not spinning even when i put on reverse or first gear?


Is the rear driveshaft turning? If it is, likely you either have a broken axle or a blown gear set inside the differential. If it isn't, then there is a problem inside the transfer case.

Upgrading '84 CJ7 Headlight Switch with newer Wrangler Dash Switc


They work on the same principal, so as long as the amps and volts match up on the switch they should.however you will have to "eyeball" the size to see if the newer one will adapt right.

Blinkers don't make noise


When exit the vehicle, on your way into the store, just casually turn your head and then check to make sure your lights aren't on. Later on, at your convenience, you might want to check the fuse box and see if there isn't a fuse blown, as this might solve the notification nightmare. Good Luck and Godspeed to you mam.
