Fuse #32 keeps blowing?

Hi,

From what I'm seeing, it powers the PCM relay. We switched the relay before with no success. If you remove the relay, does the fuse still fail?

I don’t believe the fuse fails if the relay is removed. I thought we were unplugging everything related to fuse 32 which was in the very first photo I sent. Things like the o2 sensors, transmission solenoids, etc. Then plugging each one back in and seeing if the fuse blows?
But I will follow your instructions if you think this is a better route.

Update...

Fuse does not fail if the relay is disconnected.

Fuse does fail when PCM is disconnected.

Hi,

If the fuse doesn't fail with the relay removed but does when you connect the PCM, closely inspect the PCM connector pins on both connectors to see if there are any damaged or touching/shorting.

The reason I said to disconnect the relay and PCM is because most of the things getting power is triggered via the PCM.

Pins on both connectors all look to be in good order.

Hi,

If the pins are in good condition, then either we have a short in the wiring between the relay and PCM or the PCM has an internal fault causing the fuse to fail. Are you able to get a good look at the wiring?

Let me know.

Joe, I’ve narrowed the problem down to a short in the wiring between the relay and PCM.

Hi,

The best thing to do is replace the wire itself with one that is equal in gauge and length. You will need to re-pin it to make it work with the connectors.

Is that something you feel comfortable doing?

Other than that, you can try going a little at a time piercing the wire to see where the problem starts and stops and cut the wire and splice it with a new section of wire.

Let me know.

I think I could replace the whole wire, seems easier. Do you have any instructions on doing that?

I believe the wire to be replaced is orange and yellow, correct?

Hi,

I'm not sure about the wire color of the one you found faulty. Also, the manuals don't provide directions for this type of repair.

Let me know.
