Hello,
I have a four door 2007 Honda Civic. All three passenger door lock went out at the same time. I can lock and unlock manually but my remote entry does not work on them. I looked at the fuses and they seem to be in good condition. Are there any suggestions to fix this issue? I have had the car for 7 years. and only about four months ago did the lock start behaving this way.
Thank you,
Chase

 

welcome to the forum. possible master switch on the drivers control panel going bad. check to see if each door and be operated at each door its self. make sure you don't have a door master lock/unlock switch in the down and lock position.

 

Under dash fuse/relay box, MICU (multiplex integrated control unit) does the work of the relays for unlock and lock.
Fuse 25 feeds power to the relays. But since it feed to driver door also and it works that it is probably not the fuse
Check for water intrusion and a wet MICU box (might be in kick panel?)

 

 

a little trouble shooting is a lot cheaper than a MICU box for 200.00.

 

Always troubleshoot.
Test and find the fault
Don't throw parts at it
Cost too much and almost never get it right on the first or second tries

 

Do the power door locks work normally when switched manually from the driver's door switch, and not the remote control, or is that not functional either?

If the power door locks work fine when switched manually, but not when the remote is used, it could be the remote, or receiver not is to blame.
