Fuse panel?

I've been getting O2 sensor codes for almost a month now. CEL is on. Codes are: P0036, P0141 and P0054. I've had my O2 sensor replaced (twice now). AC Delco is in there right now (bank 1 sensor 2). I took it to a shop and they said there's no battery voltage at the O2 sensor fuses/circuit inside the fuse box. He said the wiring "visually looks fine" and that I need a new fuse box. Does this sound right? He said the circuit inside the fuse box is what gives power to the O2 sensor wiring. The battery had the normal 12 volts. I just want to make sure this is even possible since I've already put about $1,000 in my car within the last month. I just don't want to get a new fuse box put in for $300 more and find out it was something else.

Thanks! He highlighted on the diagram where there's no battery voltage - Emission 1 and Post O2. He said there's a third area he couldn't test - Power distribution schematics - that could also be bad. I just wanted to make sure this would be possible before sinking more money into this thing. I've spent at least $500 on things people told me I need and it didn't fix anything.

The mechanic told me that there's no voltage at the circuit for the O2 sensor inside the actual fuse block and that the heater circuit that goes to my O2 sensor gets its power from the circuit inside the block. He said he was 100% sure but I wanted to be sure it could actually be the block itself before replacing it.

where is the fusebox on my car. I found the one under the hood is that the only one

I have an 2005 Malibu LS 3.5L which recently had 30 minutes of downpour rain into the car as all the windows were down. Ever since, there is a rapid clicking sound coming from the front fuse box(relay?) Removing the low/hi beam relays stops the clicking. The battery seems to drain due to this. The battery is a 3yr old Interstate which has been problem free until now. Could getting the interior totally soaked have made something in the car short out? Will air drying eventually fix this problem or do I have bad relays? Any help is appreciated!

How do you get into the engine compatment fuse box. I've located it but there are no direction in the manual for opening it and I don't want to break it by forcing it. Thank you 1

Thank you ! Ill check it out !

I need to know what are the proper relays for each position in the fuse box. I can't trust that we have the right ones in any position. There are a mix of after-market relays and we were given a different relay as a replacement in two positions leaving me not able to trust any of them and would like to know what the proper parts are for each position of the fuse box. After that maybe safe substitutes. Our 2002 Malibu running hot and neither radiator fan comes on with a/c or not. Replaced heat sensor. Fans come on when sensor unplugged. Used to run at one notch above 1/4 gauge, now just above or below half a notch half a gauge. Believe we need to replace thermostat and flush radiator, and are going to. We just need to eliminate any possible relay issue. All fuses are good. My Son and I would appreciate any help, it's our only vehicle right now. Thank you.

Where is the stereo fuse on a 2001 chevy malibu, I was installing a new stereo in my car and forgot to disconnect the battery terminal and hit wires together and they smoked so im sure its the fuse but I cant find it. Checked the driver side door fuse box and under the hood and none of those are blown.

I accidentally moved my drivers seat up too far and the circuit breaker tripped. I am not sure how to reset it can you tell me how?
