OK guys I have an issue with my 1998 Honda Civic Hatchback I wanted all the power options in my hatchback like an EX coupe or an SI so I followed this guide. 96-98 Civic EK Power Window/ Lock/ Mirror Conversion.

Everything in the car works as it should from door locks windows go up and down mirrors can be adjusted. My issue is when I switch over on the mirror switch to the driver side to adjust the mirror angle towards left the door locks trigger and lock.

I want to mention the only part of the how to I did not follow was the wiring for the rear wiper since I deleted that option on my car. I have 2 floor harness both brand new I tried both same issue, I have doubles of the door harness that also did not fix the issue, I have multiple mirror switches also have the same result, I tried different fuse box under the dash also same issue. I tried a different master switch on the driver side that did not help.

I have not changed the dash harness I am kinda at a lost as to what I can do to correct this issue anybody know what might be the issue. If somebody ends up helping me resolve this issue I am willing to paypal for your help really want this issue resolved.

Thanks,

DieMaster

check all your grounds. my first guess is maybe the or connectors are mis-wired and or you got a short somewhere. the door locks trigger on ground so maybe the mirror motor is trying to ground itself though the door locks.

I have sanded to bare metal for all the floor harness grounds, are you suggesting another ground might be the issue?

I have the one by the driver seat contacting bare clean metal and the one under the dash on the other side of the fender touching bare clean metal. Suggestions are welcome.

My guess would be a swapped wire somewhere. Like where they meet at the door connector? Was there any cut and soldering on the harness?

Same car as this thread?

Was this^ issue fixed?

TheHatchMan

I did not cut anything or solder anything in the cabin harness or doors.

TheHatchMan

I want to start fresh and disregard that thread since I have started over with a fresh floor harness matching the year of my car and have multiples on the cabin electrical components this time around.

TheHatchMan

Up.

Than you have an issue with the door harness. That needs to be looked at. Look for exposed wiring.

Former User

You didn't mention the donor car information (year, EX, LX, or HX, coupe, etc.) for the floor and door harnesses.

What does this mean?

TheHatchMan

Floor harness is brand new from dealer 98 ex 2 door coupe purchased from Ryan from Autofair. Door harness I have two tried both from 96-98 ex coupe uncut other than the speaker wire plug but those are just taped off.

I have multiple harness for the doors all from the 96-98 range I have multiple switches for the mirror so basically I have doubles and triples of electrical components I been trying to figure out if that was the issue. I hope that helps let me know if you need more info to clarify.

What are the donor trims for the door harnesses?

Is G551 connected?

TheHatchMan

I have two door harness they are from a 96 and a 98 ex coupe I tried both same result.

Yes, both grounds are connected the one you are pointing out here in the diagram and the the one on the floor by the driver seat.

I have sanded down the metal where the loop connectors makes contact with the chassis as well to ensure a good ground.

Disconnect the mirrors from the door harness and try to again with the mirror controls.

TheHatchMan

I have tried that the switch still engages the lock.

tony_2018

disconnect the drive side door lock switch and try again

TheHatchMan

I have tried that as well same symptoms.

The problem almost surely reflects the differences between pins 15 and 21 in the floor harness connector C556 and the driver's door harness connector for Civic years 96-97 and Civic year 98.

tony_2018

Only thing you can do is have the door panel out, get a dsm, and check for continuity to ground when the door locks itself after attempting to adjust your mirror. Once

Time to get technical.

Sounds like there's something going on with the floor harness. That link you provided gives you diagrams for all functions involving the doors. Have you looked into that?

TheHatchMan

Do you know what the color code should be for a 98? A big thanks for providing the color codes and plug.

Former User

Do you mean wire colors?

Do you understand how to fix the problem now?

TheHatchMan

Yes I would like to know what the colors of the wires would be for those pin outs for the 98 harness.

I believe I do understand the issue you are indicating that the issue is with those pinouts and the floor harness. So those two need to be checked to make sure they mesh with the floor harness. Am I following you correctly?

Former User

Wire colors to and from C556 pins 15 and 21 are shown in both diagrams in post #18.

From what I can tell, your problem can be most easily fixed by swapping the two door harness connector pins corresponding to the two floor harness connector C556 pins 15 and 21.

TheHatchMan

Understood thanks man if this is the fix I will for sure send you a paypal payment it has been driving me nuts and I have asked so many people to help.

tony_2018

Thats insane to have a minor change like that happen from a 97 to a 98, was there a reason? I mean it was still obd2a, 96-98 right?
