Hey guys.

My buddy has a 99 or 00 civic lx.

The other day getting out of his car from the back seat he asked me to lock the door.

"didnt cause i was assuming he has power locks"

He then told me his locks dont work.

I flipped the switch and sure enough 0 out of the 4 doors locked.

part 2

in my car I have done the power window conversion on my hatch, and I have the door lock switch on my car even though itsn ot functional.

So i pop mine off and hook it up to his car and flipped the switch.
still no go.

could this be a relay or fuse gone bad?

 

bump

 

curious to see the result.

 

You know it's not the switch - that's a good first step, but it really could be a whole host of other things - get out the Helms manual and start diagnosing. These can be downloaded from http://hondatech.info/ , and they are very good at tracking down problems if you follow them carefully and are systematic. Get out your voltmeter.
