So my low beams will not work. They worked for a little bit blew the fuses then I replaced the fuses and they don’t work. Some days low beams will work for a little then stop completely. The fuses under the hood and dash are good. These bulbs are brand new from Autozone. The most expensive ones too like 60 bucks I don’t think they’re bad. Something odd is that all bulbs on my vehicle replaced but the right blinker blinks very fast compared to my left signal. Not sure if that is related or not. Wipers module broken as well and is being replaced not sure if that’s related but someone mentioned combination switches on an old thread I read so I thought I’d mention it.

Thanks in advance!

 

Inspect all the wires for broken, frayed. Blinker blinking fast is most likely a bad ground wire on that side either front or rear.

 

The wires coming from bulb all seem to be oem no issues at all, as far as the grounds go, Do you have a diagram of where all the ground is so i can check them?

 

Which specific fuses blew? Post a picture.

Did you test the light switch with a multimeter?

 

Fuse 21 / 20 blew under dash.

and used test light and driver side lit up but passenger did not. Picture is what I probe and lit up.

 

When highbeam is on and I tested using light none would light up my probe. Probe is grounded testing for 12v. Or is this set up incorrect.

Canada Civic with DRL?

21/22 not 20 that my mistake.
As far as the switch testing with multimeter i dont know how to do that

 

Currently, both low beams do NOT work, but both high beam DO work. Is this correct?

Do you have a multimeter?

 

Correct, and yes I have a multimeter

 

Using a test light, you detected voltage at the left headlight connector but not the right headlight connector.

(1) For each headlight connector, what was the wire color at the connector pin that you tested in each connector? (2) What did you use as ground for each voltage test?

 

Sorry been busy with exams, so as the ground I use the bolts for the coilovers going to chassis. So on the picture the circle was tested with light and both sides lit. Then when highbeam is turned on the left pin lights up when tested on both sides.

 

Update: now low beam and highbeam won’t work at all. Light bulbs are brand new sylvania most expensive set they were like 60 I doubt it blew out. Not sure what’s going on now. Can’t be bad switch right if the probe test worked

 

No mention of wire colors.

The headlight connector has three wires:
1) Ground for both low and high beams
2) Power for low beams
3) Power for high beams

Based on your information, you only tested voltage at the wire for high beams on both sides.
Repeat the voltage tests on the low beam wire or the high beam wire on both sides using the headlight ground wire as ground for each test. Use your multimeter to measure the exact voltage readings.

 

Which wire is the ground? I cant tell because one side has two wires and the top doesnt have a wiring going directly behind it.

 

Look at the circuit diagram I posted. The ground wire is Black (red rectangles). I also showed the colors for the power wires (red rectangles).

 

Low beam both sides read the same.


High beam driver side read 12.11 High beam passenger side read 12.04

test light using the ground from connection works well. Lights up on both low and high and both sides.

 

Your high and low beam headlights have good power and ground.

You may have purchased the wrong bulb types for your Civic.

 

Okay I’ll get new ones and see, what kind do I need? I thought as long as the plug fits it’s good.

 

Either of these bulb sets should be fine ($17 - $20 range):

 

Thanks! I’ll check these out
