Hey Honda you have a problem with your 2007 Honda Fits? On 4/5/10 after three years my Low Beam Headlamps went out together and getting home in the dark sure was fun driving with my High Beams on!!! So i took my 2007 Honda Fit Sport into my Local Automotive Repair shop. And I took along a letter that another 2007 Honda Fit Owner had the same problem (I finally tracked down the cause of my low beams failing, and it's not the headlight switch. Here's the deal, and also the reason why changing the switch works for a while, but not for good. The culprit is a bit of corroded wire leading into the plug that goes into the headlight switch. When you pull out the plug to change the switch, that bit of wire gets jiggled and electricity passes thru it again, until the corrosion comes back.) This dude goes on to say (Here's the lousy part. The bad wire, at least on my 2007 fit, is the piece that goes right into the plug. My mechanic was able to scrape away the corrosion but says the plug and a few inches of wire leading to it, should be replaced or the problem will eventually return. But HONDA does sell the plug/wires except as part of the entire instrument cluster harness, which costs about $800.00

The Problem is an Open Low Beam Groung Wire 2 the Switch due to connector resistance.
Well my fix cost me $175.00 and my Repair shop Performed a SHUNT inorder to repair the Low Beam Headlamps. As they put it "They Performed Wiring Repair due to Overloaded Circuit at the switch that cost $84.95 and HEADLAMP SWITCH Remove & Replace $67.96 Total Cost Labor $152.91 Parts $9.94 Tax $11.40= $174.25

 

This sounds like something that happened with the 86-88 Ford Escort GT. Ford used the same harness for the GT model as it did with the LX. The big problem was that the LX wasn't available with fog lights and the GT came with them. The lead which ran from the multi switch (turn, hi beam, w/s wipers) to the fog lamps wasn't heavy enough to carry the amperage required. Ford never issued a recall, instead opting for the TSB route.

The fix in the case of the Escort required replacement of a melted harness end and a heavier gauge wire. It seems to me that you should be able to disassemble the offending plug end and put a new wire in there. Your dealer should have the actual wire ends in stock, I would think.

 

Thanks for the info E=MC2 but I don't go back to the dealer after being screwed by them too many times. But I would like Honda to talk about this problem they should have know about the power to the headlamps, sure it didn't happen until 3 years later but I feel they screwed up.

 

Isn't there a kind of dielectric grease that you can put on the connection to seal out the atmosphere from causing this corrosion?

 

BraytonAK could be but when it comes to fixing my Fit I just pull out my Wallet.

 

Feds are investigating this now:
