Question about 1995 Chevrolet Cavalier

1 Answer

I have very dim headlights and tailights. Even got pulled over. Tested the fuses and some are getting less than 1 volt. Radio is very dim also. Has new battery and alternator. The ABS, radio, exterior lamps, and a couple more fuses are only getting about 0.8 volts when the rest are getting 12.5-12.6 when we tested them. Alternator is putting out 14.3 and the battery also has 14.3. Brand new ground wire too. PLease help!

Did you clean or scuff up new battery terminals and wire ends? Sounds like a bad or missing ground strap.

SOURCE: alternator not exciting

Hi ' If you changed the battery and alternator,
Check the voltage at the red wire on the alternator. if there a less than 12 volt.
Check the fuse link, that goes in the starter positive bolt.
If the fuse is bad replace and recheck the charging system.
IF charging normal. good.
If not, che the fuse in the fuse box, "" cluster".
If the fuse is blow out, replace. and check again.

OK. I hope this work for you.

SOURCE: alternator putting out 16.5volts

or and more likely... the voltage regulator either mounted on the alternator or on the wheel well is defective.

You need to get you alternator tested, it sounds like the current output is too low.

Headlight problems


Hi. That sounds like the Low/high beam switch is malfunctioning and in need of replacement. I believe this because the headlights will not come on no matter which power source is attempting to activate them. Clearly, they are not getting power. Since the high-beam indicator light is functioning and indicating HIGH BEAM it IS getting power, There is no further interruptions in that circuit, save the fuse. IF the fuse is good,.. tested good.... Then the switch is bad, if the fuse is bad... replace it. If this doesn't solve the problem You have blown all your headlights simultaneously, or lost all the connectors to the headlights all at once, or possible got so unlucky as to lose all connectivity to just the headlights magically. I'd bet the fuse if I didn't believe that you would have checked that before posting the question here, and that doesn't account for the indicator to be stuck, so.... This pretty much leaves the switch ol buddy, sorry.

Dash lights will not work?


Check that your tailights/parking lights are working (not the headlights) as this fuse and relay feeds all the instument lights too.... Fuse 15amp TAIL & Tailight Relay

If not then check:
The rheostat (also known as the dimmer switch) may be faulty
as it controls all the illumination of all the backlight bulbs and other dimable switches/indicators.

In general bulbs all together draw a fair amount of current so it is possible that the wiring or ground at the major supply junction feeders has failed but that is a less common problem.

So check the rheostat dimmer wiring area first as all illumination power goes through it.

There is further simple testing we can do with the three wires at the rheostat you can check the entire illumination system.
If you jumper the white/blk to the white/blk all the illumination lights should come on (that means the rheostat is bad).

Or use a voltmeter and measure the green rehostat wire to ground it should be 12volts (if not time to check the fuse, relay and wiring)

If not then finally declare the instrument panel faulty (like burned up circuit board trace).

Note of interest: the rheostat also controls (dims) other switches not associated with the instrument cluster such as the cigarette lighter bulb and hazard switch and radio player and A/C control switch. So if those are dimming but not the instrument panel backlights then yes the instrument cluster needs fixing or a very close wiring inspection.

I have a 2003 pontic grand am i dont know why the interor lights, dash lights, and tail lights, aren t working at all! break lights work. right turn light works, left turn light clicks like 4 times faster...


The headlight switch is common to all your problems except the quick flash of the turn lights on one side the quick flash is usally a bad bulb as the tailights have two and one could be out and it'll still work just it changes the flash quicker with no load too little and it'll not blink just stay on. Theres fuses for the dash lights but the tailight fuse has to be good for it to get power. Any crash damaged lights need to be checked out as water getting into the sockets can mke a problem. The marker lights on the front do'nt work either. Fuse or headlight switch now remember that the radio has a light in it too and if someones changed the radio alot of aftermarkey readios don't use the run light as they are on withthe radio on and this wire may be touchin ground or be hooked up wrong at the lights the wire color is brown. It's highly unlikly that alot of bulbs failed at one but the car is old. Start with fuses and if the tail fuse is blown and it has an odd radio pull it disconnect it and try another fuse

Headlights and tailights won't come on on my 1986 bronco


You may have somehow accidently unplugged the headlight switch in the dash. It should not be able to be pulled off Being an 86 it may have been replaced and the retaining tabbs damaged. Try pushing the wiring harness connector back on the switch.

1986 RV blows instrument panel fuse when switch pulled


The headlight switch has a rheostat built into it to dim your dash lights, it may have shorted out. As soon as you turn on the switch this rheostat comes into play and is probably whats blowing the fuse. I think if you replace the headlight switch, it will solve your problems.

04 pontiac sunfire battery light and panel lights dim


sounds like your alternator. if you have a multimeter then turn on your car and turn your headlights on/ac and heater fan on high/wipers on and blinkers on. once they are all on hook the meter to the battery and if it reads less then 14 volts then the alt is bad. or you can just take it to a shop and have it tested.

Geo tracker lights and radio not working


power loss.
any good car elect. tech find this pronto.
just takes a volt meter to find the voltage drop point.

top fails:
1: corroded fuse box on right front finder (under fuse box)
2: did you say it kills motor too. cant figure above.

what about heater fan, it uses tons of current.
as does HL followed by tails.

20amps, 15amps and 5amps respectively

you have resistance some where.
and load , kills the voltage .

for me.
i'd:
check battery voltage , when it dims out.
then of ok 12.5v is ok key on,not started.
then check voltages at a right fender , fuse panel
all points there, 12.5vdc , same as battery v.
if OK
then
check voltage at the fuse above right knee
with load full, hl, fan, brakes, just key on.

now you know what circuit is fail ing by now.

report back with this facts.
