hello everyone,
First post and this new to me forum!
I have a 2008 CR-V that is our Dingy. I am an LED fenatic, have changed all lights inside and out, installing resistors as needed for the turn signals and the such. My headlights are also LED. I noticed a week ago that the low beams do not come on. Running light work with parking lights on and parking lights off, high beams work when signalling and when high beam switch is activated. when i turn the switch to low beam, no '0' headlights, I activate the high beams and they work put no light at all on the low beams. I installed the old headlight bulbs and no light to them either. I took apart the headlight turn signal switch and other than dirty, all the contacts looked fine, no blown fuses. I purchased a switch anyway and installed it and still no luck.
I was hoping someone could share a wiring diagram for my car so I can troubleshoot this the correct way. I have been in the HVAC for 42 years so i am very good with a meter but need the road map now.

thank you!
Tim

 

Re-check the fuses. Under-dash Fuse No. 21 (20A) provides power via the low beam head light relay (the low beam relay is incorporated as part of the multiplex integrated control unit (MICU); which is part of the under-dash fuse box assembly). After power runs through the relay, under-dash Fuse No. 16 (10A) and 17 (10A) provides power to the respective low beams.

 

tech8,
thank you!!!!!!! you hit the nail!
As I stated, we use the car as a dingy for our motorhome, so #21 is the fuse the aux. brake system says to use to power the braking system while towing. I found that the fuse holder which is pretty much a jumper, 20 amp to 10 amp for the braking system, loose,
pushed on it and voila, headlights!

thank you so much!!!!!
