2006 Honda CRV both low beams went out last night...I had to drive home using high beams since they still worked. I checked just now and the driver side bulb was blown, but the passenger side bulb was fine. I moved the passenger bulb to the driver side and the driver side headlight now works. However, neither passenger side low or high beams work now. I swapped both fuses and relays and they are functioning fine. What may be the problem?
BTW, it's quite possible the passenger high beam was out last night as well, I just might not have noticed. It definitely seems like an odd electrical problem since the driver side lamp was blown, but the passenger side was fine (just not getting any juice). I just finished a 2000 mile road trip on Thursday and I'm positive that everything was working fine just a day or two ago.
Also, I was hauling a small cargo trailer with an electrical hookup if that may help diagnose anything.
Well I suspect that you may have developed a problem in what's called the Multiplex unit. It's an integral part of the fuse box in Honda CR-V's. It's possible that the cargo trailer caused the problem by causing too much current to be drawn thru the system, I have a similar problem with my 2002 Honda CR-V and have been told I need to replace the multiplex unit and they are quite expensive. You may have to bite the bullet and have it checked by your nearest Honda Dealer.
