A32 Circuit Breaker Help
I know of the forums years ago but I just registered today so Hi All!
I own a 99 M/T A32 an 01 A32 A/T Brougham VIP as what its called here back home, My 99 M/T had non-working front passenger door Step Lamp Light, Power Door Lock and Power Windows. The FSM says there's a circuit breaker somewhere and I just can't seem to find it. Been months. I've check every fuse under dash and the engine bays.
I was a witness when the door lock was flickering kinda like a house short circuit, after that flicker in went dead and I haven't brought it to the mechanic to have it checked, as I used it everyday at work. One day I opened up the side trim and put direct power to the window motor it still works going down, switch the polarity it goes back up, works perfect. I assume the power door lock and the the lamp works if I find the culprit. The rest of the 3 doors work btw. I also have switched LCU02(power window switch) to my other A32 and both works on the other A32 so it's not the switch. I even tried switching LCU01(driver's controller) to give the benefit of the doubt that maybe its that's side's fault but no, both switches work in the other car.
Lastly if I turn on the dim and headlights, the power window switch still lights up, can be clearly seen at night which I say to myself there's power going in there in the switch. I just couldn't find where the fault is.
Can someone shed some light?
TIA

Ok so finally I foundsthe problem to this and fixed it myself. With this pandemic we're on. We got nothin' but time so there I go. The A32 doesn't have a fuse for the doors and all. Its never in the service manual to begin with. I just had to be sure because someone told me there is. so I removed the trim and everything was clean until my checked the harness after the door hinge under the glove box and way inside(not the white mounted ones). It was a link and was busted due to corrosion I had to jumpwire two cables so finally It fixed my power window, door lamp, and door lock(Front Passenger Side) as this was the only one giving me problems on my post. Hope this helps.
