Where Is My Solid State Relay (SSR)???

I showed the 2 places it will be in my jul14 post with photos, the 2nd photo shows it is on the top (fig. 16), that is directly from the gm service manual.

Wonder if @swathdiver ever found his?

No, it's been raining, a lot. But am due for an oil change and have to spray PB Blaster on a bunch of nuts and bolts again so I might as well drop the spare again and have a look around. Diff Fluids are coming close to due again too. Curiously, the warning has not come back on in a few weeks.

I know Wes, but it ain't there, neither of those places and some others I checked.

Ok...I MAY have found this little ******! ....the only thing is not 100% its the right relay, as the part# 25848909 doesn't line up to what I've read.........If so...its located inside of the frame rail right after the fuel cell, on on the subframe beam....trouble is the bolt heads are tucked tightly on the fuel cell side. But it may be possible to use a torx fitting a reverse the treads to loose and side out (not necessary to unthread all the way). I took pics and will try and attach....


Ok update: 99% its the right relay, cross checked with AC delco part and matched, so I changed it out. Using 5/32 socket you can reverse thread the studs out to slide out the relay, then detract the harness (I couldn't do it while attached). Overall pretty straight forward...just a ***** to actually find it...So cmon GM DO Better!

25848909 is the trailer brake control relay

Yep I figured that out too! Here's another pic for location...But basically follow the fuel cell toward the front of the truck until the first subframe and its attached to it.

well if it is any consolation I can't find mine either

Do you guys have the built in brake controller? Because there is nothing there on mine
