So for the past couple days ive been trying to fix my AC

Freon is good, all fuses seem good, grounds seem fine, and relays seem good

To start from the beginning a rat got into my engine bay and ate through a couple AC wires on the right side of the engine bay (Left side if you were outside the car) closest to the passenger headlight
strange enough the cables that were ate through was a blk/yel, blu/red, yel/wht had to cut the wires that werent ate through to install new connector and now the solid white wire doesnt give any power when i tested but all other cables do and the solid white worked the other day

i bought a used connector from the junkyard and just twisted old to new for the time being as im going to k24 swap so itll have to be removed anyway

before i put the new connector on it would blow warm ish air into the cabin after the new connector the blower motor suddenly lost power to the blu/wht wire and blu/blk wire

i also replaced the transistor still nothing idk much about cars but im still learning and would love feedback anything helps

ps sorry if this post is kinda all over the place the ac has been giving me a headache

 

Year and model of vehicle?

 

1995 civic hatchback (CX) if that makes a difference

 

For the blower motor, the relevant fuses are under-hood Fuse No. 37 (30A) and under-dash 13 (7.5A). Check/re-check both of those fuses.

With the ignition turned ON, the positive side (+) of the blower motor wiring (Blu/Wht wire) should have power if both fuses and relay are good. Did you use a voltmeter or tester to check for power on the Blu/Wht blower motor wire?

You want to determine is it a power or ground issue.

The Blu/Blk wire to the blower motor is the negative ground (-) source coming from the resistor or heater control panel; the ground sources are controlled by the heater control panel.

 

the fuses seem fine i don’t have a volt meter just a cheap light tester and blu/wht was getting no power

and imma try my best to describe this

at the relay you have these connectors for the relay
1/2
3/4
connectors 1/4 were giving off power when i tested them and after i replaced the wires that got ate by a rat connector 1 doesn’t give off power anymore and connector 4 does (i hope that makes sense)

blu/blk is ground so i didn’t expect it to be hot but blu/wht on all speed setting never got power

i took it to a shop to get looked at along with another part since a family member insisted on it and offered to pay

so i’ll update on that once i get the car back

 

Yeah, electrical issues are a pain if you don't know where to look. I would suggest the FSM when it comes to electrical issues. It's helpful in situations like this.

 

Thanks for the tip

shop called and told me the AC control panel (interior controller) wasn’t giving power to the blower so i’m gonna try and replace that see if anything changes

 

small update for things i’ve checked with still no success

blower motor transistor is also not getting any power
blu/wht wire going to ac control panel also not getting power

grounds seem fine not corroded or rusted

fuses and relays also still seem fine
and when checking the connectors for the blower relay
1(grounded)/2(hot)
3(used to be hot/4(grounded)
(hope that made sense)

still nothing i really hope someone has a suggestion i haven’t tried yet cause winters coming soon and i no longer have heat lol

wires on the inside seem fine so i’m not sure where a break in the wiring would be if any break would be there

 

Pls tell me you’ve diagnosed it? Dealing with this issue now
