I know this is an 'old' post.

I have the same problem on my 98 Accord Sedan V6. After checking the dimmer circuit which gives me 0-20Kohms if I turn it, and after reading all the various threads regarding this problem on this forum and driveaccord.net forum, I am quite certain I have to replace the Driver's side multiplex unit.

bernardiparts.com has it at $85 + $10 shipping.

I am a bit diffident about the replacement job. I know many people have done it. can somebody point me to a detailed description for this replacement job.

Thanks.
