Question about Chevrolet Caprice Classic

2 Answers

We have a 1977 Chevy Caprice Classic coupe, 305 cid 2 bbl carb. The horn and the dome light aren’t working. The headlights, marker lights, turn signals, radio, etc. are working. Would appreciate any input as to why just the horn and dome light are inop. We will get a new bulb for the dome light, as the one in there is the same light that was in it when I bought the car approx 12 years ago. It’s the horn we’re most concerned about.

There's a 15 amp. fuse and a relay in the underhood fuse block, you should be able to hear the relay click when you hit the horn button If you don't hear a click it may be in the steering column but before you disassemble anything get some electro-contact cleaner and spray it in the crack under the steering wheel as you turn the wheel hopefully this will clean the "horn ring" and make the relay click. I hope this helps. Take care. If None of this works let Me know here if I can help, it will show up in my email.

SOURCE: 92 caprice classic turn signals not working, but

Yes, the problem is the turn signal flasher is defective. You can has two flasher relays. One for the turn signals and one for the hazard lights. That is why the hazard lights flash and the turn signals do not. Replace the turn signal flasher relay located on the drivers side of the steering column, mounted behind the instrument cluster in the convenience center. They are both mounted in the same location so turn on the hazard lights and the one that you put your finger on that is not clicking is the turn signal relay.

SOURCE: i have a 1989 chevy s10 horn radio and dome light

Check inside the drivers and passenger side door jam for the little push in type switch. 9x out of 10 one or the other will be causing the short to the dome fuse. These little **** get rusty and also get alot of wear and tear from the door opening and shutting over and over. These switchs are what causes your dome light to come on when you open your door and or likewise they shut your dome light off when you shut you door. A very good way to test to see if one of these little switchs is the couprate is to take and hook up a voltage light into the negative side battery post after you disconnect the battery negative line.. If your voltage light is on than that would mean that you have a short somewhere in your system. Now, since you already know that you are blowing the dome fuse then your already halfway there. With the light on your votage light still on indicatin a short, unscrew the little switch on the door jam and disconnect the power wire from it. Check to see if the light on your voltage light is still indicating a short, if not then you can be sure that the door jam was the coulprete. Hope this is of help.

How to change the chrome marker light bezel on a 79 Chevy Caprice Classic. This is the large chrome piece that holds in the reflector for the bulb.

Unless I'm remembering something wrong this is a very easy repair. The chrome trim that surrounds the two headlights and supports the marker lamp. This chrome trim is held on by four small but long, recessed torx screws. I think a T15 is used but please verify that. Look between the tram and the headlights. In the four inner corners they can be found. They don't stick out but they are there. Good Luck.
