hi i just did a power door conversion on my 2000 civic 4 door now the....... does not work

1) blower motor
2) interment wiper
3) wash and wipe in the wipers
4) ac light in dash
5) dome light
6) rear window defrost

and sounds like the main relay is constantly clicking does anyone have an idea what i might have done? i used a ex floor harness

The harness was from a four door? From what year?

Have you checked for blown fuses?

hi my heater fan stopped working all of sudden i have power under the hood at the relay 40 amp under the hood is good, and the 7.5 under the dash is good blower motor works if i wire it directly, what else can it be? i have 6 volts on 2-3 terminals at the rheostat

yes the harness was from a 4 door, checked the fuses found a couple blown ones, now just the heater wont work, i have power at the under hood relay and fuse. fan works if i connect it directly to 12 volt

Do fuses 55 and 17 have battery voltage on both top test tabs with the key in ON(II)?

both fuses are good and have power, anyone else have any ideas?

Might be your wiring. How did you fix the other issues?

Former User

Now check whether the blower relay in the hood fuse box gets voltage from both of those fuses.

all the other issues were burnt fuses, is the floor harness tied into heater controls? i unplugged the plugs from the floor harness the main body and the 2 that go into the fuse panel and i got the same thing. i also tried plugging in the old harness and i got the same thing.

everything else works just not the fan.

the fan relay has power on the 2 front terminals

to make things clearer,

Problem, swapped out a 2000 floor harness for power door conversion now Heater motor and rear window defrost not working.

systems: ac, rear window defrost and recirculating lights on dash flash and ac relay clicks fan does not work

Stuff i have tried: put original wiring back in no change. fan works when powered to 12 volt directly. i tried changing out fan controls on dash. 7.5 fuses for r.def. and fan are good 40 amp fuse under hood is good. i tried switching out relays in the under hood fuse panel. i have power at all fuses/relays. both cars are 2000's

i am stomped so any advise on where to go would be greatly appreciated

With the key in ON(II), does voltage reach the blower motor plug? If not, test the relay.

98greensi

ok will do. i also cannot change heat locations anymore ie floor defrost etc

98greensi

does anyone know if the 2000 civic have some kind of heater control module?

Damn i am stumped on this one. i finally got my hands on a hyness manual, and everything checks out the only thing i can see is that the control module (heater fan switch) does not have a ground does anyone have ground schematic? another thing also is that the fan has battery voltage but when i ground out the other prong i get nothing according to the manual this means bad fan but when i hook it directly to the battery and ground it works fine. at the moment i have it wired to the ignition and ground so at least i can drive it
