Just for kix try jumping the run and start relay.
Fuse #5 Pin 30 is the supply for the start relay, it is always hot. . Signal is pin #86 (hot)
Pin 30 on the run relay is always hot. Signal is pin # 85 (hot)

If those pins are not always hot there is an internal fault of the fuse box.

 

Changed that. No difference

 

Let's play logic 101; There is power at the main power lug of the fuse box, there is no power at the always hot points inside the fuse box. QED: there is a fault between the main power lug and the always hot points.

Power for the relay signal comes from the under hood fuse box to the BCM.

 

Just checked those out. No dice, I’m thinking fuse box. Is it an easy thing? Like unbolt, unplug, and switch? Or does it need anything reprogrammed?

 

There are 4 different wire bundles/connectors in the bottom half of the underhood fuse block. Hard to imagine that they all went bad/fried at the same time.


It's probably the remote positive terminal, which is part of the top half.

Disconnect the NEGATIVE battery terminal.

Then remove the positive cable and power steering wire from the fuse block.

Remove the 4 screws inside the fuse block.


Then there is a clip on each side, and the top half comes off.

The rear wire bundle/connector is clipped into the top half. In the first pic, it is unclipped and laying in the bottom half.

 

Watch about the first half of this video, it might help you.

 

There is a lot of internal connections. My guess is the main lug burned. As far as I know all of the boxes are the same, the difference from model to model is the the connector pins and what fuse does what. If you buy a NEW one for an HHR you get fuses and relays in the correct spots, if you buy one for a C10 you get one with fuses and relays for a C10.

 

That sounds like what I need to do. Thanks for taking the time to help me. This forum is a great place with some really smart people. I’ll let you know if this solves it.

 

Don do you mean S10 ?

 

It's just an example, he's not saying that a fuse block from a C10 will fit.

Looking at several diagrams and part numbers, I'm going to guess that the part gets a different number if any fuse/relay position is different.

There are several different covers also. Obviously they will all snap on. But there are many part numbers, presumably because they have different map stickers on them.

So C10 might fit, it was produced up until 2002. S10 has been resurrected, it may fit also.
